阳煤集团三矿地区煤炭开采难度定量评价

Quantitative Evaluation of Coal Mining Difficulty in the Third Mine of Yangquan Coal Group

以阳煤集团三矿地区为例,通过计算该地区的断层破坏指数、褶曲强度系数、褶曲复杂系数、老顶支撑系数、采煤层顶底板软化系数等19个影响指标,构建了隶属函数模型对该区煤炭开采难度进行了定量评价。结果表明:该区煤炭开采难度等级为3级,即煤炭开采较容易,评价结果与该地区实际煤炭开采难度基本一致。

Aiming at the difficulty of coal mining research for the Third mine of Yangquan coal group,in order to conduct quantitative evaluation of coal mining difficulty in the Third mine of Yangquan coal group,the 19 influence indicators（such as fault damage index,fold strength coefficient,fold complex coefficient,old roof supporting coefficient,softening coefficient of roof and floor of coal layer etc.） of the area are calculated,and the membership function evaluation model is established to conduct quantitative evaluation of the coal mining difficulty of the area.The study results show that the coal mining difficulty of the area is regarded as 3 by checking the coal mining difficulty level table,it is indicated that the coal mining is easier in the area.The above evaluation results related to the coal mining difficulty of the Third mine of Yangquan coal group is basically consistent to the actual coal mining situation,which can also provide some reference for the coal mining quantitative evaluation of the similar coal mines.
