摘　　要：文章以山西同忻煤矿1611(3)工作面为分析对象,分别对比了在4.3 m/d、7.2 m/d、10.8 m/d、13.2 m/d四种推进速度下,工作面来压步距、煤壁片帮和冒顶、超前支承压力等参数变化情况,确定了最佳推进速度为10.8 m/d,可为该煤矿后续工作面的开采工作提供参考。By comparison of four advancing speeds of 4.3 m/d,7.2 m/d,10.8 m/d and 13.2 m/d at 1611(3)working face of Tongxin Colliery,the paper determines the optimal advancing speed of 10.8 m/d according to the change of weighting step,coal wall spalling and roof fall,advance abutment pressure and other parameters,which can provide reference for the subsequent mining work of the coal mine.
