復雜性科學及其在煤礦安全行為問題研究方面的啟示
摘要:復雜性科學是一種前沿的系統(tǒng)科學 近年,中國的煤炭工業(yè)迅速發(fā)展,并為經(jīng)濟的增長作出了重要的貢獻。煤礦的安全問題對于煤炭工業(yè)的可持續(xù)發(fā)展來說歷來是一個桎梏 。站在一個新的視角來看,煤礦安全問題的研究是一個值得重視的課題。本文把近幾年中復雜性科學的發(fā)展與其在煤礦安全行為問題研究方面的啟示相結合,對其進行了系統(tǒng)的研究。
關鍵詞:復雜性科學 礦井安全 混亂
1、復雜性科學的發(fā)展
復雜性科學的研究對象為復雜的系統(tǒng)或系統(tǒng)的復雜性。不同的學者對于復雜性給出了不同的定義。但卻難以給出一個精確的定義??偨Y各種觀點,系統(tǒng)的復雜性主要可以概括為以下幾個方面:1 ) 系統(tǒng)各單元之間是一種廣泛且緊密的網(wǎng)絡式聯(lián)系。所以,其中任何一個單元的變化都可能影響到其他的單元并引起其他單元的變化。2)系統(tǒng)是包含眾多因素的一個多層次,多機能的結構。每一個層次是一個單元,它有助于實現(xiàn)一個特定的機能。3 ) 系統(tǒng)中包含有一個回饋循環(huán)。 在發(fā)展過程中,系統(tǒng)能不斷的學習并改進其層次結構和機能結構。4 ) 系統(tǒng)是開放的,它與外界有密切聯(lián)系并相互作用。5 ) 系統(tǒng)具有不斷演變的自我適應能力。6)它不能用常規(guī)的理論與方法來解釋。7 )系統(tǒng)的特性曲線是動態(tài)與非線性的。8)系統(tǒng)具有跨越水平得特性,例如包含,關聯(lián),互相影響和作用。
復雜系統(tǒng)存在于我們世界的各個領域:物理系統(tǒng),生態(tài)學系統(tǒng),社會系統(tǒng),等等.根據(jù)生命現(xiàn)象得的獨立單元,智能信息結構,原料銷售的起伏 ,社會的進步和衰退,人體的免疫系統(tǒng),這些系統(tǒng)的共同特征是,在不確定的變化之后會出現(xiàn)一些不確定的秩序。研究復雜性的目的不僅僅是揭示和描述其運轉(zhuǎn)原理,而是要解決如何預測和處理復雜系統(tǒng)中那些以前無法解釋和處理的問題。
在1984年,在諾貝爾物理學獲獎人穆拉伊.耶爾-曼,腓力.安德森,和諾貝爾經(jīng)濟學的獲獎人 阿羅的贊助下,集合了一群來自物理學,經(jīng)濟學,生態(tài)學原理和計算機科學方面的研究專家,創(chuàng)建了著名的圣菲研究所。他們集中這些領域的人員和思維,去試圖揭示復雜系統(tǒng)的主要原理。布魯塞爾大學在普里果金領導下和尼里克斯合作,撰寫了著名的“復雜性研究”一書,并為這一學科打下了堅實的基礎。在我國由錢學森提出的開放綜合性“龐大系統(tǒng)”的研究和國外復雜性的研究是異曲同工.由錢學森提出的開放綜合性“龐大系統(tǒng)”原理,應用定性分析法和定量分析法來討論這些系統(tǒng),集中專家小組(來自所有領域的專家),資料和所有的信息通過有機計算,并將各種原理和多種學科的知識有機的結合,這與圣菲研究所的研究方法是一樣的。
在專業(yè)領域,關于復雜性的主要理論學說有:
布賴恩.亞瑟將效益遞增叫做Owner Gain(擁有者增益)。卓越的科學家例如:馬里.熱爾曼 , 喬治.科旺和菲力普.安德森也提出相似觀點,他們認為學科應該朝著一致性的方向發(fā)展,他們也 提出“Agent(作用因素)”和“Emergence(緊急事件)”的觀念。約翰.奧朗首創(chuàng)了因子運算 ,系統(tǒng)分類法,推動了神經(jīng)網(wǎng)絡運算的發(fā)展,推斷出了復雜系統(tǒng)的自我適應性。Chris Longton 建立了人力壽命理論,推動了激勵個體理論的發(fā)展,并提出復雜引起注意的觀念。斐莫將神經(jīng)網(wǎng)絡,固有運算,分類系統(tǒng)模式,自動催化模型和免疫系統(tǒng)模式結合在一起,運用連結機制的思想提出了結點聯(lián)想模型。丹麥物理學家佩爾.鮑克提出自我組織臨界性原理,考夫曼提出了自我組織臨界性條件的理論 。
由于復雜性的突出表現(xiàn)形式較多,根據(jù)上述的原理試圖建立新的相關的組織管理理論,解決曾經(jīng)在傳統(tǒng)的管理理論下被認為是難題的問題,目前已經(jīng)有了一些進展?!皬碗s性:一個產(chǎn)生于秩序和混亂交界處的學科”從理論角度描述了復雜性系統(tǒng)理論的來源和啟動過程。最早出版的學術著作是“復雜性,管理者和組織”和“混亂:誕生的一個新的學科”,在此領域中,后者被認為是非常經(jīng)典的著作。“在國內(nèi)的領域:研究自我組織和復雜性原則”表明復雜性學科在經(jīng)濟和組織理論方面有著巨大的重要性?!邦I導者和新的學科:保證總體的狀況良好的組織性研究” 研究量子結構和 綜合的理論并將其引入領導者和組織學科?!氨罎⒌幕靵y:探索的復雜世界的簡單規(guī)律”描述了過去在混亂和復雜性中發(fā)現(xiàn)的一些簡單規(guī)律。“機構中的復雜性和創(chuàng)造性”敘述了將新的學科應用到 機構的發(fā)展和改革中去。將復雜性學科應用到企業(yè)的經(jīng)營中,這絕對是一門新的學科,因為復雜性學科本身是一個發(fā)展中的學科,沒有現(xiàn)成的和成熟的理論結構可以應用。但是,復雜性學科所提供的新的思維模式對于企業(yè)管理來說真是筆巨大的財富。
2、介紹煤礦安全問題的研究形勢
目前,在我國的能源消耗結構中煤炭占據(jù)了70%以上。在將來的30-50年間,這種能源消耗結構不會改變。自從我國建國以來,煤炭工業(yè)迅速發(fā)展并未國家的經(jīng)濟建設做出了重大的貢獻。煤炭生產(chǎn)主要受地質(zhì)與環(huán)境的影響。安全是煤炭生產(chǎn)的一條生命線。它是在研究煤礦安全生產(chǎn)問題時,擺在我們面前的一個重要課題。
當前我國對于煤礦安全生產(chǎn)問題的研究主要表現(xiàn)在以下幾個方面:
2.1、從技術方面進行研究
這方面的研究開始較早并取得了許多成績,主要包括事故的預防和控制技術,例如瓦斯,煤塵,滲水,煤的自然,等等。在近年間,國有大中型煤礦在安全技術和機械設備上做了重大改善。
2.2、從心理學方面進行因果分析
陳啟昌提出人為因素在傷亡事故的發(fā)生中起重要作用。易亦勤對于煤礦安全問題的實質(zhì),傷亡事故的原因進行了深入的研究,尤其是心里因素和行為因素以及其原因,表現(xiàn),原理,控制手段。林澤巖經(jīng)研究發(fā)現(xiàn),無論是國營煤礦,國有煤礦或者私有煤礦,人為因素引起的事故與死亡次數(shù)要高于偶然因素引起的事故次數(shù)。他認為心里因素例如,人的意識和情緒是使事故發(fā)生的主要原因。
2.3、從系統(tǒng)科學方面進行研究
馮兆瑞和崔國章通過因果研究,安全檢查表,事件樹,事故樹和危險性預測,對生產(chǎn)系統(tǒng)中的不安全因素和潛在的危害進行了系統(tǒng)的分析。李金平和李中海將“safety starlight huge system (安全之光龐大系統(tǒng))”管理方法應用到了煤礦安全管理方面。他認為現(xiàn)今的體制 不再是金字塔式的,他們更趨向于“universe(全域) ”;“Huge System(龐大的系統(tǒng)) ”,這意味著安全管理問題超過了安全的本身。梁秉鐸試著將立體經(jīng)營模式,循環(huán)經(jīng)營模式和螺旋上升式經(jīng)營模式應用到煤礦安全管理中去。張和平和王管昌將煤礦安全系統(tǒng)工程的理論與方法應用到了對煤礦安全生產(chǎn)的評估中。
國外的研究文獻和書籍涉及的安全問題較多是來自美國和歐洲,但只很少注意煤礦的安全問題.這是由于石油為主體的能源消耗結構代替了煤炭為主體的能源消耗結構。
海因里克根據(jù)大量的統(tǒng)計資料對事故進行研究,他注重于強調(diào)事故發(fā)生的真正原因.行為心理學者(哈登,舍茨,舒奇曼,1961)提出了通過轉(zhuǎn)變勞動者的行為可以減少事故的發(fā)生的概念.尼克.緯紗.胡斯特,史蒂芬.揚,伊恩.唐納德 ,與胡.吉普森灑,通過對歐洲四個國家的六個主要危險地點進行的研究發(fā)現(xiàn),在有重大隱患的工廠或企業(yè),只要有正確的安全態(tài)度和良好的PSMS性能,就可以減少事故的發(fā)生.T. P. 凱爾與J. A. 麥克德米德提出使用規(guī)章制度來保證工人的安全態(tài)度的方法.尼爾.米奇森,喬治 .A. 帕帕扎基斯 研究了如何對安全體系進行評價和實施.
比吉特 瑞斯姆森納與庫爾特 E. 彼得森創(chuàng)建 了一個適于工廠機能的社會技術系統(tǒng)模型,并運用這一模型為標準來評價安全管理的效果.艾莉森 G 洛登堡在他的研究報告中總結了影響安全管理成果的六項因素。這些因素是管理者的職責,獎勵,交流和回饋,選擇,順序和參與。他還分別研究了各個因素減少人身事故的作用程度。N 麥克唐納 ,S 科里甘 ,C 達 ,S 克魯密提出了一個自我調(diào)整模型用來測試不同的體制如何安全經(jīng)營。這種模型更注重與人和團體間的相互作用 。格奇提出了TSM概念(完全安全管理)。這個安全管理方法是根據(jù)TQM 的 基本原理形成的,并用于指導實踐。
它可以表明在目前關于安全研究的原理和方法主要集中于特定的問題,并限于確切的空間 和時間。魏因施泰因認為這些方法強調(diào)于技術需求并傾向于短期影響.必須承認,過多的煤礦事故早已成為困擾我國煤炭生產(chǎn)的問題。作者有以下觀點:
1)無論是在建礦,領導生產(chǎn)還是經(jīng)營過程中,安全問題已經(jīng)成為煤礦生產(chǎn)中一個非常重大的事情.
2)礦山安全行為系統(tǒng)是一個復雜系統(tǒng).它的復雜性主要表現(xiàn)在安全行為的復雜性與不確定性;安全行為體系的復雜性,多單元,多功能,多指標;安全行為預測的非線性和不確定性;決定生產(chǎn)與控制;資料的非協(xié)調(diào)性;安全行為系統(tǒng)的不平衡和混亂;各個因素的相互作用,安全行為系統(tǒng)中的周圍環(huán)境的相互影響,自我組織,自我適應過程的復雜性,等等.
3)行為的復雜性是一個參數(shù),相當于巨大的高維概率空間.其主導特征是行為軟件,小風險處理(敏銳 模數(shù) 鈍化 ),介質(zhì)尺寸(統(tǒng)計分析不確切的管理行為)
4)在煤礦的不安全行為系統(tǒng)中存在一種反向演變
5)對于礦山安全問題的研究來說,根據(jù)復雜性系統(tǒng)的研究采取措施也許是一種有用且靈活的方法.
3、復雜性科學在煤礦安全行為問題研究方面的啟示
啟示一:把握整體.煤礦安全問題是非常復雜的.這意味著它作為一個整體具有相當新的特性,傳統(tǒng)方法的思想面臨著巨大的挑戰(zhàn)。分析這類問題的時候,我們習慣于將它們劃分成簡單的可分解的要素,分別研究再綜合其結果。雖然這種規(guī)規(guī)矩矩的解析法曾推動了科學技術的進步,但是隨著科學技術的發(fā)展,這種單獨分析的解析方法的局限性越來越明顯。當一個問題被分解成各個要素的時候,會造成一些重要因素的丟失。煤礦安全問題是一個重要的生命系統(tǒng)。一旦它被劃分,他將會失去原有的意義。因此 ,研究煤礦安全問題必須把握整體模式。
啟示二:過多個體的自發(fā)的行為將要引起整體規(guī)律的集聚,亦即:著重于“合并 ”和自我組織。系統(tǒng)的組織能力或者生成結構出自個體的無意行為則被稱作"意外事故"。在無外部事物的影響下,能引起高級系統(tǒng)和復雜系統(tǒng)內(nèi)部自動組織的能力被稱作自我組織能力。用于觀察意外事故和自我組織的方法完全不同于傳統(tǒng)的結構和管理體制的組織方法。在這里提供一個新的視角來研究煤礦安全問題:不應該有意的去限制和控制不安全行為,而應該強調(diào)灌輸自我安全行為意識的步驟和方法。
啟示三:熟悉安全的行為相關的周圍事物,因為它能引起自我組織。如何找到引發(fā)安全行為自我組織和意外事故的最好手段:熟悉安全的行為相關的周圍事物是最好手段 。普里果金曾經(jīng) 指出一個系統(tǒng)引起自我組織需要滿足三個方面的指標:第一,它應該是一個開放式系統(tǒng),與外界有能源,物質(zhì),和信息和交流。第二:系統(tǒng)應該是動態(tài)的和超過平衡的。第三:在系統(tǒng)中存在某個回饋過程使其得到迅速的發(fā)展。普里果金指出的第三方面,信息共享機制是必定要發(fā)展的,因為系統(tǒng)作為一個整體來說于周圍事物是相互依存的。自然現(xiàn)象中的這三項自我組織前題,為煤礦安全問題中的安全行為自我組織提供了重要的啟示。一個具有安全行為自我組織能力的煤礦具備 以下特性 :1)員工有高度的自覺性;2)由下至上確立安全指標;3)新的安全觀念和手段層出不窮。4)適當?shù)姆答佔饔每梢愿淖儚碗s的周圍環(huán)境。
啟示四:確認能夠產(chǎn)生安全行為凝聚。相關的外界介質(zhì)如何引起安全行為自我組織?按照普里果金的研究,這取決于微觀的水平的起伏。亦即:微觀層次方面,員工的安全行為的擾亂過程 ,由于個人行為引起安全行為自我組織和意外事故的活動并決定了整體水平方面整個煤礦的運轉(zhuǎn) 方向。
啟示五:整體和部分的聯(lián)合演變。個體是如何改變集體的?安全問題的每個部分與其他部分之間都會相互影響,相互作用,它將引起安全系統(tǒng)中所有部分的聯(lián)合演變。
啟示六:安全行為系統(tǒng)是逐漸形成展開的,形成過程的本身也是逐漸的,演變本身(煤礦安全系統(tǒng)的循環(huán)流程和規(guī)律)也是逐漸形成的。規(guī)律是變化的,所以我們也可以改變它們。
啟示七:在領導煤礦生產(chǎn)中發(fā)現(xiàn)問題并建立安全行為系統(tǒng)。耗散結構的理論表明要預測綜合安全系統(tǒng)或構造的演變結果幾乎是不可能的?;煦缋碚撝赋鲈诜蔷€性系統(tǒng)中,在初始狀態(tài)一瞬間 不會引起極端明顯的結果。由這兩方面判斷,要預測復雜的安全問題是不可能的。最好的預防方法是創(chuàng)造 。一旦非預期的問題出現(xiàn)的時候,應該立即做出決策,因為規(guī)律本身不會重復。所以,管理者必須注意根據(jù)事故來轉(zhuǎn)換模式:從不預測結果,而是領導建立煤礦安全行為系統(tǒng)。
到目前為止 ,復雜性系統(tǒng)仍然不是一個精確的科學理論,但它是一各綜合的概念 .這個概念以提前應用到了具有強大計算能力的計算機技術的研究,邏輯推理和原理應用當中,也許會發(fā)現(xiàn)一些簡單規(guī)律中的一些動態(tài)模型,并設法找到各簡單并零散的元素間的交互作用的一致性和目的性的整體變化.總之,它為我們研究煤礦安全問題提供了一個新的平臺.

Science of Complexity and Its Revelation on Study of Coal Mine
Safety Behavior Problems
Chen Hong
(School of Management, China University of Mining & Technology, Xuzhou 221008, Jiangsu, China)
Abstract: Complexity science is the foreland of system science. In recent years, coal industry has got rapid development in China,and does important contribution to economy growth. The problem of mine safety has always been a shackle to the sustainable development of coal enterprises. It is a significant task to study mine safety problem from a new angle of view. This paper has a systematic thought combined with the development of complexity science in recent years, and forms some revelations on the study of coal safety problems.
Keywords: science of complexity; coal mine safety; chaos
1 Development of Complexity Science
The science of complexity takes complex system or the complexity of system as its study objects. Different scholars give different definitions to complexity. It is difficult to give an exact definition. Combined with some points of view, the complexity of system can be mainly embodied in the following aspects: 1) The connections between cells of system are wide and tight with network. Therefore, the change of any cell will be affected by the changes of other cells, and will cause changes of other cells. 2) System consists of many agents with a multi-level and multi-function structure. Every level is the cell of upper level, and is helpful to the realization of a certain function. 3) System consists of feedback annulus. In the process of development, system can learn continuously and have a recompose of its level structure and function structure. 4) System is open to environment; it has a close relationship with environment, and has an interaction with environment. 5) System is an evolvement system with self-adapting ability. 6) It cannot be explained with traditional theory and method. 7) System has the characteristics of dynamic and non-linearity. 8) System has the character of span level, such as embedded, interlinked, inter influenced and affected.
Complex system exists in all fields of our world: physics system, biology system, human society system,etc. From the life phenomenon of a single cell, structure of the brain and intelligence, ups and dow ns in the stock market, to rise and decline of the society, immunity system of the human body, the common character of these systems is that behind uncertain changes, there comes out some uncertain orders. The aim of complexity study is not only to reveal and describe the locomotion principles, but also to solve the problem of forecasting and controlling of the complex system that seems unsolvable and cannot be handled before [1-5].
In 1984, with the support of Nobel Physics Prize winner Murray Gell-mann, Philip Anderson, and Nobel Economics Prize winner Arrow, assembling a group of research experts from the fields of physics, economics,theory biology and computing science, the most famous Santa Fe Graduate School was established. They tried to reveal the general principles dominating the complex system by gathering personnel and thoughts of these fields. Brussels College under the leadership of Prigogine and coauthored with Nilicos, wrote the famous book “Exploration of Complexity”, and set a strong foundation to this science. The study of opening complex “huge system” in our country represented by Qian Xuesen is different in approach but equally satisfactory in result with study of complexity system abroad. The concept of opening complex “huge system” abstracted by Qian Xuesen, the synthetic integration methods of qualitative and quantitative methods to deal with these systems, to combine expert group (experts from all fields), data and all information with the computing technology organically, and to combine theories and knowledge of various subject together organically, have the same study methods with Santa Fe Graduate School.
In specific field, the main theory contributions on complexity are as follows:
Reward Increase by Degrees, is also called Owner Gain, by Brian Arthur. Outstanding scientists such as Marry Gellman, George Cowan, and Philip Anderson also put forward the thought of subject conformity, they think that subject should be in the direction of development from revert to unity, they also put forward the concepts of “Agent” and “Emergence”. John Holland initiates gene arithmetic, sorter system, impels the development of nerve network arithmetic, deduces the characters of complex self-adapting system. Chris Longton sets up the manpower life theory, impels the development of cell motivator theory, and puts forward the concept of complex attractor. Fammer unites nerve network, inheritance arithmetic, classifying system model, auto-catalyze model and immunity system model together as node-associate model by the thought of connectionist. Denmark born physics Per Bak puts forward the concept of self-organization criticality.Kauffman puts forward the theory of self-organization criticality conditions.
As the most protruding manifestation of complexity, organization management theory is trying to set up new relative theory on the basis of theories above to solve problems regarded as puzzles and dilemma under traditional management theory, there are already some progress at present. “Complexity: a Science Born at the Edge of Order and Chaos” describes the origin and starting process of complex system theory from the angle of theory founder. The earliest academically published books are “Complexity, Supervisor and Organization” and “Chaos: Naissance of a New Science”,the latter is considered the most classical works in this realm. “At the Home of Universe: Study on Principles of Self-organization and Complexity” demonstrates the great significance of complexity science in the field of economy and organization theory. “Leadership and New Science: Organizational Study of the Universe in Order” studies the quanta structure and complex theory and introduces them to leadership and organization science. “Collapse of Chaos: Exploring the Simple Laws of Complex world ” describes some simple laws in the history of finding chaos and complexity. “Complexity and Creativity in Organizations” narrates how to apply new science to the development and transformation of organizations. It is an absolutely new subject to apply complexity science to the management of organizations, because complexity science itself is a science in the process of formation, with no existing and ripe theory structure to be applied for. But the new model of thinking and metaphor that complexity science supplies for organization management is really a great wealth.
2 Present Research Situation of Coal Mine Safety Problems
At present, coal occupies over 70% in energy consuming construction in our country. This kind of energy consuming structure will not change in 30-50 years in the future. Since the foundation of our country, coal industry has got rapid development and has done a major contribution to the national economy. Coal production greatly influenced by geology and environment. Safety is a Life Line of coal production. It is a significant subject in front of us to study safety problems in coal production.
The current research on safety problems of coal production in our country mainly lies in the following aspects:
2.1 Research from Aspect of Technique
The research of this aspect starts early and has many achievements, involving primarily the technological prevention and controlling of disasters such as gas, coal dust, water leakage, coal self-burning, etc. In recent years, the state-owned large and medium-sized mine enterprises have got substantial improvement in the aspects of safety techniques and equipments.
2.2 Cause and Effect Analysis from Aspect of Psychology
Chen Qichang thought that contrived factors had important function in the occurrence of casualty accidents[6]. Yi Yiqin connected with the reality of mine safety problems, probed into the causes of casualty accidents, especially the factors of psychology and behavior, and their causations, representations, principles,and controlling measures[7]. Lin Zeyan found in his research that no matter in state-allocated mines, state-owned local mines, or village-owned(including individual) mines, the accident number and death number resulted from factitious adventure are higher than that of accidents by chance[8]. He thought psychological factors such as people’s consciousness and emotion are the main reasons for the cause of accidents.
2.3 From Aspect of Systematic Science
Feng Zhaorui and Cui Guozhang had a systematic analysis on the unsafe factors in the production system and their possible damages to the system by means of cause and effect analysis, safety check table, incident tree,accident tree, and fatalness pre-analysis[9]. Li Jinping and Li Zhonghai applied “safety starlight huge system”management method into mine production safety management[10]. He thought that nowadays organizations are no longer like pyramids, instead, they tend more like “universe”. “Huge System” means to manage safety problems beyond safety itself. Liang Bingduo tried to apply stereoscopic mode of management, circumvolve type of circulating management, and spiral ascension type of management into coal safety management[11].Zhang Heping and Wang Guanchang applied the theory and method of mine safety system project into the evaluation of safe production in coal mines[12].
The abroad research literatures and books concerning safety problem are more from America and Europe,but little aims at safety problem in coal mine directly. This is due to the petrolem-dominated energy consuming structure instead of coal-dominated energy consuming structure.
Heinrich (1881-1962) studied accidents on the foundation of a great deal of statistic data, and emphasized on the real causes of accidents. Behavior psychologists (Haddon, Scherzer, & Suchman, 1961) put forward the idea that accidents can be reduced by changing workers’ behaviors. Nick W.Hurst,Stephen Young,Ian Donald ,and Hu Gibson, by research on the six major hazard sites in four countries of Europe, they found that right attitude to safety and favorable PSMS performance can reduce accidents happening on site or enterprises with great hidden risks[13]. T.P. Kelly and J.A. McDermid put forward the method to keep safety state by system measures[14].Neil Mitchison,Georgios A.Papadakis research how to appraise and perform the safty system[15].
Birgitte Rasmussena and Kurt E. Petersenb established a society technology system model for factory functions, and used this model as bases to evaluate the effect of safety management[16]. Alison G. Vredenburgh summed up six factors that would affect successful safety management in his research report. These factors are managers’ responsibility, encouragement, communication and feedback, selection, training and participation. He also respectively studied the influence degree of each factors to reduce personal damage[17]. N. McDonald , S.Corrigan, C. Daly and S. Cromie put forward a self-regulation model to test different organizations how to manage safety. This model stresses espacially on interactions between human and organizations[18]. Goetsch put forward the idea of TSM(total safety management). This is a safety management method formed from the basic
priciple of TQM and used as a guide to practice[19].
It can be seen that research theories and methods on safety are mainly focused on specific problems at present, and they are limited to the validity of space and time. Weinstein thinks these methods emphasize on technology requirement and prefer short-term effect[20]. It is necessary to recognize the problem of excessive coal accidents that has puzzled coal production in our country for a long time. The writer has the following standpoints:
1) Safety problem has been a fatal thing for organizing, decision-making and operating of safe coal production.
2) Mine safety behavior system is a complex system. Its complexity mainly lies in complexity and uncertainty of safety behavior environment; complexity of safety organization behavior of multiplayer,multi-cell, multifunction, and multi-target; non-linearity and uncertainty of safety behavior prediction,decision-making and controlling; non-symmetry of information; non-balance and chaos of safety behavior system; interaction of all factors, and complexity of the process of interaction with complex environment and self-organization and self-adaptation of safety behavior system, etc.
3) Behavior complexity is a property, corresponding with great high-dimension probability space. The dominant characteristics are soft behavior, small risk process (acumen modulus passivation ), medium-sized range (statistic contiguity of uncertain management behavior).
4) There is reverse direction evolvement in unsafe behavior system.
5) Management countermeasures based on complex system analysis may be a valuable supplement to research of mine safety problems
3 Revelation of Complexity Science on Study of Coal Mine Safety Behavior Problems
The first revelation is: hold the whole. The safety problem in coal mine is very complex. Thi
