摘要
对大冶铁矿尖林山矿体无底柱分段崩落法回采进路采矿爆破振动速度的测试与研究表明 ,质点爆破振动速度与单响最大爆破药量和测点到爆心的距离密切相关 ,符合《爆破安全规程》
This paper introduces a blast vibration measurement in a sublevel caving stoping at Daye Iron Mine,Wuhan Steel and Iron Company, China.The results of the measurement and the correlative research show that the particle vibration velocity of measuring points depends on the maximum interval charge of millisecond blasting and the distance from blast point, and it accords with the proposed formula R=(K/V) 1/n Q m in the regulations for blasting practice China.
