摘要
为论证安庆铜矿深部特大型矿柱开采过程中充填体的自立高度、可暴露面积,开展了安庆铜矿深部采场充填体稳定性研究,在充填体现场调查、充填体力学性质的现场测试和室内实验的基础上,采用3种理论计算方法分析了充填体的稳定性,为特大型矿柱回采方案设计提供了依据。
In order to demonstrate the possible self - standing height and exposed area of fill body during mining deep extra large pillar, a study was made of the stability of backfill in deep extra large stopes in Anqing Copper Mine. Based on the field investigation of backfill, in-situ tests and laboratory experiments on the mechanical properties of backfill, the stability of backfill is analyzed respectively using three methods of theoretical compute. The calculated results provide basis for the design of stoping scheme of extra large pillar.
