摘要
在石料开采工程中,应用深孔毫秒延时挤压爆破技术,减少爆破震动危害,石料块度比较理想,取得良好的爆破效果。本文详细介绍了爆破方案的确定、爆破孔网参数的设计,并结合现场地形、地质条件的变化不断对其进行校正和优化。
Deep hole millisecond compression blasting was applied to stone quarrying, resulting in reduced harmful blasting vibration, anticipated blasting fragment size and ideal blasting effect. The present paper discussed in detail the determination of blasting program, the design of blasting pattern parameters and the correction optimization of these parameters by considering the varying site terrain and geological condition.
