1、摘 要本设计说明书是山西朔州平鲁区华美奥兴陶煤矿的井田设计,矿井位于朔州市平鲁区下面高乡下韩佐沟村陶村乡白家梁村一带,行政区划属于平鲁区陶村乡管辖,其地理坐标为:1122824-112 31 16,北纬39 2802-39 2911。本设计为井田4号煤层的矿井设计,该煤层地质结构简单,平均煤厚5.4m,煤层倾角17,属于近水平煤层,有煤尘爆炸危险,为瓦斯矿井。矿井工业储量为3420万t,设计可采储量为2884万t。设计生产能力为120万t/a,服务年限为17年。经过技术条件和经济条件对比,选择主斜井副斜井双斜开拓方案,回风井选择了立井。井下和主斜井煤炭运输采用皮带运输,辅助运输采用绞车牵引矿车
2、方式,技术工艺简单,操作方便。矿井通风采用中央分列式通风。总而言之,通过对地质条件的分析以及矿井建设的技术经济条件和安全性来看此次设计的开拓方案、采煤方法等均能满足矿井的开采需求。关键词:斜井开拓;瓦斯矿井;中央分列式通风。ABSTRACTThe design instructions are the design of the well field in the huameo Xingtao coal mine in Pinglu District, Shuozhou, Shanxi. The mine is located in the village of huozuo village,
3、 south of Pinglu, Shuozhou, Pinglu District, Shuozhou. The administrative division belongs to the pottery village of Pinglu district. Its geographical coordinates are: 112, 28 24, 31 16, 39 degrees 28 02 -39 29 in the north latitude. 11. This design is a mine design for No. 4 coal seam in the minefi
4、eld. The coal seam has a simple geological structure, an average coal thickness of 5.4m and a coal seam dip of 17 degrees, which belongs to the near level coal seam, and has the danger of coal dust explosion, which is a gas mine. The industrial reserves of the mine are 34 million 200 thousand T, and
5、 the designed recoverable reserves are 28 million 840 thousand T. The design and production capacity is 1 million 200 thousand t/a, and the service life is 17 years. Through the comparison of technical conditions and economic conditions, the double inclined development plan for the inclined shaft of
6、 the main inclined shaft is selected, and the shaft is selected by the return air shaft. The underground and the main inclined shaft coal transportation uses the belt transportation, the auxiliary transportation uses the winch to pull the mine car way, the technology craft is simple, the operation i
7、s convenient. Central ventilation is adopted in mine ventilation. In a word, through the analysis of the geological conditions and the technical and economic conditions and safety of the mine construction, the design and mining methods can meet the mining needs of the mine. Keywords: Inclined shaft
