摘要
在露天、地下同时开采的铜景山铜矿,应用由微机控制的瞬态记录仪测定露天爆破地震波对地下工作面影响以及它在地下的衰减规律,通过测定分析,可以得到允许的一段爆破炸药量、临界振速以及安全距离等各项参数。
The Tonglushan Copper Mins operated by surface and underground mining simultaneously uses the instantaneous recorders controlled by microcomputer to measure the effect of the seismic waves from open-pit blasting on underground stopes and their weakening regularities. Through the measuring and analying, the parameters such as permissible explosive amount for single-stage blasting, criticalvibration velocity, and safety distance can be gotten.
