双壁路堑硐室松动爆破参数设计及效果分析

PARAMETER DESIGN AND RESULT ANALYSIS OF CHAMBER LOOSE BLASTING FOR EXCAVATION OF DOUBLE WALL CUTTING

通过合理选择高边坡条件下松动爆破参数 ,有效地控制了硐室松动爆破的破坏范围 ,达到了保护性爆破松动的目的。通过爆破效果分析 ,提出了硐室松动爆破在今后保护性硐室爆破设计中应注意的问题。

Through reasonably selecting the blasting parameters under the condition of high slope,the damage range caused by chamber loose blasting was effectively controlled and the blasting results was consistent with the design According to the result analyzing,some problems were put forward to which the attention should be paid in the design of chamber loose blasting with slope protection in future
