【正文】 ign of Yangzhuang colliery. It contains ten chapters: an outline of the mine field geology boundary and reserves, throughput and labor system of the mine, the main roadway of the mine, the roadway of the mine, disposal of roadway and mining method, transportation of underground, mine lifting and transportation, mine ventilation and safety, and the economic and technologic index of the mine.The Yangzhuang colliery field lies in the Mining town Huaibei city of Anhui province. The total area of the mine is length of the mine field is on average, the width of the mine field is . Its dip angle is 10 degree on average. The main exploitation coal seam is 5＃.The industry reserves of the mine field are million tons and the useable reserves are tons. It’s service life is 68 years. The normal flow of the mine is 190 m3/h in average. The mine is a low gassy mine. The deploitation manner is shafts with two levels . Transportation Roadway used to transport coal mine car , Using transport coal and uses rack track and coolie car in subsidiry method of mine ventilation in this shift is mixed ventilation.The labor system of the mine is “threeeight”.It produced 330d/a.The mining method of the mine is fullymechanized longwall in the strike.There is one working face in the mine, and the other face for preparation. The throughput of Yangzhuang colliery is million tons per year. The length of the longwall face is 200 m.The special part is: the research about the design of the support and protection in the mining face in the situation of hard roof.The translation part is: Rock bolt mechanical analysis and its application to engineering.Keywords: Industry reserve: Labor system: Mine ventilation: Mining method.目 錄一般部分1 礦區概況及井田地質特征 .................................................................................1 礦區概況 ??????????????????????????????????????????????????????????????????????????????????????????????????????1 井田地質特征 ??????????????????????????????????????????????????????????????????????????????????????????????3 煤層與煤質 ??????????????????????????????????????????????????????????????????????????????????????????????????82 井田境界和儲量 ...............................................................................................14 井田境界 ????????????????????????????????????????????????????????????????????????????????????????????????????14 礦井工業儲量 ????????????????????????????????????????????????????????????????????????????????????????????15 礦井可采儲量 ????????????????????????????????????????????????????????????????????????????????????????????163 礦井工作制度及設計生產能力、服務年限 ...................................................20 礦井工作制度 ????????????????????????????????????????????????????????????????????????????????????????????20 礦井設計能力及服務年限 ????????????????????????????????????????????????????????????????????????204 井田開拓 ...........................................................................................................23 井田開拓的基本問題 ????????????????????????????????????????????????????????????????????????????????23 礦井基本巷道 ????????????????????????????????????????????????????????????????????????????????????????????34 主要開拓巷道 ????????????????????????????????????????????????????????????????????????????????????????????425 準備方式采區巷道布置 ...................................................................................49 煤層的地質特征 ????????????????????????????????????????????????????????????????????????????????????????49 采區巷道布置及生產系統 ????????????????????????????????????????????????????????????????????????50 采區車場選型設計 ????????????????????????????????????????????????????????????????????????????????????546 采煤方法 ...........................................................................................................59 采煤工藝方式 ????????????????????????????????????????????????????????????????????????????????????????????59 回采巷道布置 ????????????????????????????????????????????????????????????????????????????????????????????747 井下運輸 ...........................................................................................................76 概述 ????????????????????????????????????????????????????????????????????????????????????????????????????????????76 采區運輸設備選擇 ????????????????????????????????????????????????????????????????????????????????????76 大巷運輸設備選型 ?????????????????????????????????????????????????????????????????????????????????????798 礦井提升 ...........................................................................................................81 概述 ????????????????????????????????????????????????????????????????????????????????????????????????????????????81 主副井提升 ????????????????????????????????????????????????????????????????????????????????????????????????829 礦井通風與安全 ...............................................................................................83 礦井通風系統的確定 ????????????????????????????????????????????????????????????????????????????????83 礦井風量計算 ????????????????????????????????????????????????????????????????????????????????????????????88 礦井阻力計算 ????????????????????????????????????????????????????????????????????????????????????????????93 選擇礦井通風設備 ??????????????????????????????????????????????????????????????????????????????????100 安全災害的預防措施 ??????????????????????????????????????????????????????????????????????????????10610 礦井基本技術經濟指標 ...............................................................................108專題部分1 堅硬巖層的力學特性 .....................................................................................111 堅硬頂板力學特性 ??????????????????????????????????????????????????????????????????????????????????111 堅硬頂板分類 ??????????????????????????????????????????????????????????????????????????????????????????1122 堅硬頂板采場礦山壓力及其顯現規律 .........................................................113 堅硬頂板采場礦山壓力顯現特征 ??????????????????????????????????????????????????????????113 單一長壁采場上覆巖層移動規律
