錢營孜煤礦2.4 Mt/a新井設(shè)計
摘 要
本設(shè)計包括三個部分：一般部分、專題部分和翻譯部分。
一般部分為錢營孜煤礦2.4 Mt/a新井設(shè)計。錢營孜煤礦位于安徽省宿州市西南，區(qū)內(nèi)有南坪集至宿州市的公路和四通八達的支線與任樓、許疃、臨渙、童亭、桃園等礦井相連。青疃～蘆嶺礦區(qū)鐵路支線從勘查區(qū)南部由西向東穿過，向東與京滬線、向西與濉阜線溝通。合徐高速公路從勘查區(qū)東北部穿過，交通十分便利。井田走向長度約6 km，傾向長度約3.2 km，面積約35.08 km2。主采煤層為32號煤層，平均傾角為12°，平均厚度為2.89 m。井田工業(yè)儲量為159.69 Mt，可采儲量為99.32 Mt，礦井服務(wù)年限為51 a。礦井正常涌水量為434 m3/h，最大涌水量為885 m3/h。礦井絕對瓦斯涌出量為1.72 m3/min，屬于低瓦斯礦井。
根據(jù)井田地質(zhì)條件，提出四個技術(shù)上可行的開拓方案。方案一：立井單水平開拓上山開采，巖石大巷開拓；方案二：立井單水平開拓上山開采，煤層大巷開拓；方案三：立井兩水平開拓上山開采，巖石大巷開拓；方案四：立井兩水平開拓上山開采，煤層大巷開拓。通過技術(shù)經(jīng)濟比較，最終確定方案一為最優(yōu)方案。水平標(biāo)高-720 m。
設(shè)計首采區(qū)采用采區(qū)準(zhǔn)備方式，工作面長度200 m，采用綜采一次采全高采煤法，礦井年工作日為330 d，工作制度為“三八制”。
大巷采用底卸式礦車運輸，輔助運輸采用礦車運輸。礦井通風(fēng)方式為分區(qū)對角式。
專題部分題目是工作面大推進度運輸保障技術(shù)，錨網(wǎng)支護是這類巷道的主要支護手段。闡述了沿空巷道上覆巖層結(jié)構(gòu)、圍巖應(yīng)力分布、圍巖變形的一般規(guī)律。并通過對現(xiàn)場實測數(shù)據(jù)的整理分析，總結(jié)了類似條件下巷道的礦壓顯現(xiàn)規(guī)律，以指導(dǎo)沿空巷道的支護設(shè)計。
翻譯部分題目是水泥漿性能對充分注漿錨桿拉拔承載能力的影響。
關(guān)鍵詞：錢營孜煤礦；立井；采區(qū)布置；一次采全高采煤法；分區(qū)對角式；雙巷掘進
ABSTRACT
This design can be divided into three sections: general design, monographic study and translation of an academic paper.
The general design is about a 2.40 Mt/a new underground mine design of qianyingzi coal mine. The qianyingzi Coal Mine located in Suzhou City, Anhui Province, southwest, and the district the Nanping set to Suzhou City Highway and ease of extension to any floor, Xutuan Linhuan Tongting, Taoyuan mine connected. Ching Tuan ~ Luling mine railway spur line from the southern part of the exploration area from west to east across the east and Beijing-Shanghai line, west and Sui Fu line. Hefei-Xuzhou Expressway from the exploration area northeast through the traffic is very convenient. Ida is about 6 km strike length, tendency to a length of about 3.2 km, covering an area of approximately 35.08 km2 in Main Coal Seams in the No. 32 coal seam, with an average inclination of 12 °, the average thickness of 2.89 m. The Ida industrial reserves of 159.69 the Mt of recoverable reserves of 99.32 the Mt mines the service life of 51 a. Mine normal inflow of 434 m3 / h, the maximum inflow of 885 m3 / h. Mine the absolute gas emission is 1.72 m3/min, a low-gas mine.
Ida geological conditions, four technically feasible to open up the program. Program: vertical shaft single-level open up the mountain mining, rock roadway development; program: vertical shaft single-level open up the mountain mining, coal seam roadway development; three programs: Shaft two level open up the mountain mining, rock roadway development; program: Shaft level to open up to the mountain mining, coal seam roadway development. Technical and economic comparison to finalize the program for the optimal solution. Level elevation of -720 m.
Mining area to prepare the way for design of the first mining area, face length of 200 m, using fully mechanized coal mining mining method, mine working days for 330 d, the system of work "38" system.
Roadway with a hopper mine car transport, auxiliary transport tramcar transport. Mine ventilation mode partition diagonal.
The thematic part of the topic face big push transportation security technology, bolting with mesh is the main means of support for this type of roadway. Described the general laws of the overburden on the gob structure, stress distribution, the surrounding rock deformation. And collation of field data analysis, summed up the apparent laws of rock pressure tunnel under similar conditions to guide along the empty roadway design.
The translation part of the topic of the slurry properties of fully grouted anchor pull-carrying capacity.
Keywords: qianyingzi coal mines; shaft; mining area layout; mining mining method; partition diagonal; double Roadway Excavation
