摘要
露天煤矿台阶爆破是在地面上以台阶形式推进的石方爆破方法,台阶爆破按照孔径、孔深不同,分为深孔台阶爆破和浅孔台阶爆破。通常将炮孔孔径>50mm、孔深>5m的台阶爆破称为露天深孔台阶爆破。由于爆破环节较多,并且主要为人工操作,因此必须对爆破全过程进行精细施工,规范操作,保证爆破作业施工安全。
Open-cast mine footstep balsting is the rock blasting method that promoting in the way of footstep on the ground,the footstep blasting can be divided into deep hole bench blasting and bench blastingaccording to different aperture and hole depth.Usually the blast hole diameter is greater than50mm,morethan5m deep hole bench blasting is called deep hole bench blasting in open pit blasting.Due to many aspects and mainly for manual operation,so fine construction must be made in the whole blasting process,and operate standardize to ensure the construction safety of blasting operations.
