金属矿床深部开采的几个技术问题

Several Technical Problems in Deep Mining of Metal Deposits

金属矿床进入深部开采后，由于地应力大而导致地压活动频繁、顶板与围岩失稳及岩爆等事故，严重影响矿山正常生产。为此，结合红透山铜矿深部开采，开展了深部开采技术的研究，提出了采用连续开采、全面充填等技术措施，效果显著，对类似矿山具有推广价值。

When the metal deposits have come to the deep mining stage,the accidents of frequent ground pressure activities,the unstability of the ceiling and surrounding rock and rock burst caused by the great ground stress can have serious effect on the formal mine production.Therefore,the technical investigation on the deep mining was made in combination with the deep mining of Hongtoushan Copper Mine.The suggested measures of continuous mining and whole filling have achieved remarkable effects,which is of the popularization value to other similar mines.
