3、煤矿2号煤层，设计图纸共十四张，说明书共十章。根据采矿工程的需要和特点，重点设计为第四、六、九章，其他如井底车场、井下运输及提升设备仅做一般的选型计算。葛屯煤矿位于山西省翼城县西部、沁水煤田沁水盆地西南边缘，行政区划属翼城县葛屯镇管辖。其地理位置为北纬353845355000，东经11148451120152.5。区内交通十分方便。翼城县乡间公路(三级)从选定的矿井工业场地南缘通过，进场公路直接与该公路相接。经此公路往西南方向行约6km在北张村与晋（城）韩（城）公路相连，继而可通向全国各地 井田内主要含煤地层为二叠系下统山西组和石炭系上统太原组，共含煤11层，煤层总厚10.9m，含煤系数9.1
4、%。主要可采煤层为山西组2号煤层和太原群9+10号煤层。本矿井设计主要是开采2号煤层。2号煤层：结构简单、埋藏稳定，直接顶为泥岩或炭质泥岩、煤线与粉砂岩复合层，老顶为K8砂岩，底板为泥岩或砂岩。在本井田范围内，煤层厚度为0.464.37m，一般厚3.20m，井田大半部可采，东部不可采。本井田划分为五个盘区，采用主斜副立井开拓方式，回采工艺采用后退式、一次采全高综合机械化采煤法，采用“三八制”作业制度。工作面的设备有双端可调双滚筒采煤机、滑移支架、可弯曲刮板运输机、破碎机、转载机等。顶板管理采用滑移支架，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，采用连续运输车作为辅助运输
