摘要
结合某矿山分段凿岩阶段出矿嗣后充填的采矿方法,利用LS-DYNA软件对中深孔爆破对充填体安全稳定性的影响进行数值模拟,提取动载荷作用下充填体内部一系列质点振动速度,加以对比分析,以此确定单段起爆药量等爆破参数,控制爆破对充填体的影响,达到安全生产的目的。
According to the mining method of sublevel drilling stage room stoping subsequent filling, the effect on fill- mass produced by the medium-length hole blasting was simulated using the LS- DYNA software. Basing on the comparative analysis of a series of particle vibration velocity extracted from the interior of the fill-mass, the blasting parameter of the charge per delay was determined so as to control the effect on the fill-mass by blasting and realize the goal of safety production.
