引言无论是在剥岩量大的矿山,还在在山脊型露天矿生产初期,实行高台阶开采,对于缩短矿山基建时间、加快剥离、减少开拓采准工程量、强化矿山开采是颇有裨益的。但是现有的穿孔设备不能也不适用于高台阶(台阶高20-30米)穿孔,而采用碉室爆破在一般条件下又不可能获得满意的爆破效果,这样就限制了高台阶剥离、采矿的推广应用。 Introduction It is beneficial to shorten the construction time of mines, speed up the stripping, reduce the amount of engineering exploration and mining and strengthen the mining of mines, both in the mines with large amount of stripping rocks and in the early stage of the production of ridge-type open-pit mines. . However, the existing perforation equipment can not and does not apply to the high level (20-30 meters high) perforation, and the use of chamber explosion under normal conditions and can not get a satisfactory blasting effect, thus limiting the high-level stripping, mining The promotion and application.
