摘要
针对小龙潭矿采场降段和扩帮,爆破振动对周边村民的影响日益突出。通过理论分析及现场试验,合理确定孔间孔内微差时间,通过现场爆破振动测试、比较,降振效果明显。
Accordance with the slope lower-sect and expanding rib of Xiaolongtan mines(belonys to Xiaolongtan bureau of mines) concussion of blasting has increasing effects on its surrounding villagers.Based on the theoretical analysis and on-the-spot experiment,delay Time In-hole and between-holes is fixed reasonably,through the test and comparison of on-the-spot concussion of blasting,concussion-decreased effects are obvious.
