摘要
神东煤炭集团三道沟煤矿井田构造简单,含煤地层为侏罗系中统延安组。其中,八盘区大采高工作面主采煤层厚度平均6.7m,最大采高达到7.1米,倾角一般1°~3°,开采条件十分优越。本着提高资源回采率,降低投入成本的原则,采用大采高一次采全高的采煤工艺来开采5-2煤层。通过地质条件分析和类似矿井大采高现场工业实践,合理确定了三道沟煤矿85201工作面综采配套设备。
In Sandaogou Coal Mine of Shendong Coal Group,the geological structure is simple and the coal bearing strata belongs to Yan'an group of Jurassic system. The average thickness of main mining seam is 6. 7m and the dip angle is 1 ~ 3°in eighth mining area. In order to improve the recovery rate of resources and reduce the cost,the full-seam mining technology can be used to mine the 5-2coal seam. By analyzing the mine geological conditions and analogizing the mining practice of similar mines,the equipment matching and selection of No. 85201 fully mechanized mining face was reasonably determined.
