束状孔大量高效采矿技术的开发与应用

Development and Application of the High-efficiency Bunch-hole Mass Mining Technique

基于创新的束状孔当量球形药包爆破技术与束状孔变抵抗线爆破技术开发的束状孔大量高效采矿技术,综合了球形药包爆破和深孔阶段爆破的优点,凿岩硐室布置成凿岩巷道的形式,实现高分层水平大量连续落矿及整体区域崩落采矿,开采效率高,成本低,在矿山采空区安全治理、阶段大量连续开采、露天转地下平稳过渡大量采矿等领域具有广泛的应用前景。

Based on the mass innovative bunch-holes equivalent spherical cartridge blasting technology and the variable resistance lines of bunch-holes blasting,the high efficiency bunch-hole mass mining method is developed.This method integrates the advantages of cartridge blasting and deep-hole blasting.The drilling chamber are arranged to be tunnels to realize the continuous mass mining with high level blasting and the overall regional caving in high efficiency and low cost.It has a wide application in the mine safety management of mined-out area,high stages continuous mining,mass mining during open pit transferring to underground mining,etc..
