山西大平煤业有限责任公司大平煤矿矿井通风设计 摘要：本毕业设计为山西大平煤业有限公司大平煤矿0.6Mt/a的通风设计。山西大平煤业有限公司位于山西省长治市襄垣县，井田南北长4.0km，东西宽3.5km，井田面积为7.9301km2。地形最高点位于井田西南部，标高为990m，地形最低点为井田东北部，标高为882m，最大相对高差108m。井田内主采煤层为3号煤层，煤层厚5.09～7.20m，平均厚度6.25m，煤层倾角为3°～8°，煤层稳定全区可采。根据山西大平煤业有限公司的实际条件，经过技术和经济比较，确定矿井开拓方式为主斜井副立井综合开拓，采煤方法为综采放顶煤开采。通风方式采用中央，抽出式。 关键词：中央分列式；矿井通风设计；通风方式；设备选型。 The ventilation system design of Daping Coal Mine Abstract：This Graduation Design is the ventilation system design of Daping oal mine whose capability is 0.6Mt/a. Daping coal mine is located in Xiangyuan County, Changzhi City, Shanxi Province. The area of Daping coal mine is 7.9301 square kilometers while the length of north to south is 4.0 kilometers and the length of west to east is 3.5 kilometers .The highest point of terrain is located in the southeast with the level of 990 meters, The lowest point of terrain is located in the northwest with the level of 882 meters. The maximum relative height difference is 108 meters .The main coal seam is No.3 coal seam, its thickness ranges from 5.09 meters to 7.20 meters, the average thickness is 6.25meters. The dip angle of the seam ranges from 3°to 8°. The seam is stable and can be mined. According to the actual conditions of Daping coal mine, based on the comparative analysis in technical and economic aspect, the mine exploitation is determined as combined shaft with vertical shaft and inclined shaft. The coal mining method is full-mechanized top-coal caving mining. The type of mine ventilation system is determined as Central ventilation system, and exhaust ventilation is adopted. Keywords：central ventilation system；the ventilation system；the types of mine ventilation； equipment selection. 目录 1 前言 1 1.1 选题的目的和意义 1 1.2 国内外研究现状 1 1.3 设计的主要原则 2 1.4 设计的方法与步骤 2 2 井田自然概况及地质特征 3 2.1 井田自然概况 3 2.1.1 井田位置及交通 3 2.1.2 地形地势及河流 3 2.1.3 气候及气象 4 2.1.4 地震基本烈度 4 2.2 地质特征 4 2.2.1 矿区范围内的地层情况 4 2.2.2 井田范围内和附近的主要地质构造 6 2.2.3 煤层赋存状况及可采煤层特征 7 2.2.4 煤质特征 8 2.2.5 井田内水文地质情况 9 2.2.6 开采煤层顶底板岩石工程地质特征 11 2.2.7 瓦斯、煤尘、煤层自燃倾向性、地温及地
