摘　　要：基于钱家营矿构造地质及瓦斯赋存特征,利用组合熵对各煤层的危险区域进行预测并对瓦斯危险区域进行上行开采可行性研究.研究发现:钱家营矿7煤层瓦斯含量较大,其西北部地区为瓦斯危险区域,利用上行开采方案,可对上部瓦斯含量较大的煤层进行释放,降低危险区域的瓦斯含量,从而保证煤层的安全开采.Based on the structural geology and gas occurrence characteristics of the Qianjiaying mine,the combined entropy is applied to predict the dangerous area of each coal seam and the feasibility study of the upstream mining of the dangerous area is carried out.It is found that the gas content in the 7 coal seam of the Qianjiaying mine is large,and the northwest area is a gas risk area.The upward mining plan can release the upper gas content larger coal seam and reduce the gas content in the dangerous area,so as to ensure the safe mining of the coal seam.
