摘要
房柱法是地下开采中一种较为普遍的采矿方法,采用留设规则或不规则的矿柱支撑顶板,以达到安全开采的目的。本文以刚果(金)某铜矿为背景,由于该矿矿体有部分需采用房柱法开采,故针对矿柱尺寸进行了研究,并计算不同情况下的安全系数,以保证采矿生产的安全。
The room-pillar method is a common mining method in underground mining,regular or irregular pillars are used to support roof in order to achieve the purpose of safe mining.In this paper,a copper mine in Congo(DRC)is taken as the background,part of the orebody need to be mined by room-pillar method,special research is carried out on pillar size and safety factors are calculated under different conditions to ensure the safety of mining production.
