矿柱高阶段大直径深孔回采爆破模型与爆破参数优化

Blast Model and Blast Parameter Optimization for Large Diameter Deephole Mining of High Stope Pillar

在安庆铜矿１２０ｍ高阶段大直径深孔矿柱回采工业试验中，为指导爆破设计、改善爆破效果、降低爆破对充填体的破坏效应，建立了高阶段大直径深孔矿柱回采爆破模型，对矿柱回采爆破参数进行了优化，并应用于工业试验，取得了令人满意的效果。

n the full scale test of large diameter deep-hole mining of 120m high stope pillar in Anqing Copper Mine,in order to guide blast design,improve blast results and reduce the adverse effect of blasting on fill,a blast model was set up for large diameter deep-hole mining of high stope pillar and the blast parameters for mining pillar were optimized as well so that the test achieved satisfactory results.
