摘　　要：对于矿石价值中等、品位中等的缓倾斜中厚矿体,目前无理想的采矿方法.本文提出了一种矿房矿柱阶段性连续回采,深孔放顶处理空区的采矿方法.这种采矿方法具有普通房柱法的优点,同时又避免了普通房柱法矿石损失率大的缺点.There seems no ideal method to mine medium grade, gentle dip and medium thickness orebody.This paper introduced a new method for it, ie continuous stoping of room and pillar in stages and to fill mined bed with falling roof by deep-hole blasting. This method possesses the advantages in common with the ordinary room-and-pillar melhod, but excluding the latter's disadvantage of great ore loss.
