万吨矿井初步设计毕业设计.docVIP

摘 要 古书院矿位于位于山西省东南部，沁水煤田的东南缘，面积23.4平方公里。主要开采3号煤层。3#煤层埋藏较浅，瓦斯含量低。各层煤自燃性不强，属于不易自燃煤层。本设计的对象是3号煤层。矿井工业储量17901万吨，可采储量14221.75万吨。矿井设计生产能力150万t/a。 3号煤层为5.10米厚，倾角3到5度，距地面160米左右。采用斜井、集中大巷开拓方式。沿井田走向布置三条大巷，轨道大巷、运输大巷布置在岩石中，轨道大巷沿3号煤层底板布置。矿井移交生产至达到设计能力时，共开凿3个井筒，即主、副斜井、回风立井。主斜井装皮带，副斜井铺轨道，工业广场位于井田中部。 本井田3号煤层划分为4个采区，采用带区式准备。设计采用倾斜长壁采煤方法开采。回采工艺采用后退式、综合机械化放顶煤采煤法。作业制度为“四六制”，三班采煤、一班检修。采空区采用全部跨落法管理顶板。 矿井运输大巷采用皮带运输作为主运输，轨道大巷采用矿车作为辅助运输，通风方式为中央并列式通风。矿井总风量为76.56m3/s，主扇工作方式为机械抽出式，风机型号为：BDNo.24，n=740r/min，电机功率为390KW。 关键字：斜井 带区式 倾斜长壁采煤方法 Abstract Gu Shu Yuan Coal Mine place in Shan Xi Province is located in the south-east, south-east edge of Qin Shui Coal, Coal Mine area of 23.4 square kilometers. Major coal mining on the 3rd. 3 # coal seam buried in shallow, low gas content. Spontaneous combustion of coal at all levels is not strong, spontaneous combustion of coal is not easy. The design of the target coal seam is on the 3rd. Mine industrial reserves of 179.01 million tons, recoverable reserves of 14221750000 tons. Mine design capacity of 1.5 million t / a. Coal on the 3rd floor 6.30 meters thick, 3-5 degree angle, about 160 meters from the ground. Focus on the use of inclined to open up the way roadway. Along the mine field to the three main roadway layout, the track roadway, transportation roadway layout under coal seams in the rock on the 3rd, the wind back to the 3rd Lane along the coal seam floor layout. Mine the transfer of production capacity to meet the design of drilled shaft 3, that is, Lord, Vice-inclined, return air shaft. The main belt inclined shaft installed, the Deputy Shop inclined orbit. The transfer of the total mine production for a two-year period. Industry Square is located in the central mine. The No. 3 coal mine is divided into four mining areas, with a zone-type preparations. Designed with inclined long wall coal mining method. Extraction process using back-style, integrated mechanized sub-level c
