The reasonable hole pattern of deephole blasting was utilized to make fully use of the explosive energy to improve the crushed ratio to lower the boulder yield and to obtain better dam rocks.
In addition, the blasting vibration monitoring was discussed and the economical benefits produced after using the field mixed explosive and optimizing blasting parameters were calculated.
此外，还论述了爆破震动监测，以及使用车制炸药和优化爆破参数后所产生的经济效益。
