摘　　要：针对缓倾斜至倾斜薄矿体开采难题,提出一种进路掏槽式采矿法,该方法的采矿工艺为利用沿矿体倾斜方向的平行中深孔将矿石崩至采场两端的进路内,人员不需进入采空区,保证了回采过程中的安全性,并大大降低了贫化率,同时提高了回采效率。Aiming at the problem of mining the low-angle dip to dip thin ore bodies,this paper proposes a way of"tunnel cutting mining"method.The mining process of this method is to use the parallel medium and deep holes along the inclined direction of the ore body to cave the ore to the tunnel at the ends of the stope.The advantages of this method are that people do not need to enter the goaf,which ensures the safety during the mining process,reduces greatly the dilution rate and improves the mining efficiency.
