摘要
红透山坑口是一个开采50多年的老矿山,地质资源在不断的减少,合理回收采场矿石底柱,增加回收矿石量,使之稳产高产已经是一个迫在眉睫的问题,提出实施人工假底,为合理回收采场矿石底柱,加大矿石回收量,为安全生产提供科学的保证。
Hongtoushan pit is an old mine with 50 years.Geological resources are declining,recovery stope ore pillar reasonably,increasing the amount of recovery-ore to make high and stable yield has been a pressing issue.Proposed the implementation of artificial false bottom,for a reasonable recovery of stope ore pillar,provide a scientific guarantee to safety production.
