太宝山梁小药室松动控制爆破

SMALL-CHAMBER LOOSE CONTROL BLASTING IN TAIBAOSHANLIANG MOUNTAIN

太宝山梁东端山体系露天大爆破残留工程，地质条件和周围环境较复杂。经方案比较，对该工程的剥离采用了小药宝松动控制爆破，达到了预期的目的，有效地控制了爆破效应危害，爆破产生的岩墙和大缺少，在破碎岩体的同时处理了爆区内的采空区。

The east of Taibaoshanliang mountain was the remanent work from larg blasting, where the geological conditions and surrouding environment was more complicated. Through the comparison with various plans, the small-chamber loose control blasting was used in the stripping of this remanent work. The expected objectives has been fulfilled, the harm of blasting effect being controlled effectively, the remanent rock ribs and large fragments resulted from the blasting being less, and the mined-out area in the blasting zone having been treated while fragmenting the rock mass.
