露天矿区滑坡压煤后减少二次剥离的回采方法

A landslide coal mining methods to minimize secondary detachment

露天采场的边帮滑坡是最常见的环境地质问题,作者以呼伦贝尔某煤矿为例,针对露天矿坑边帮滑坡压煤问题,提出了一种预留煤柱、正常开采、条带清理、条带开采、内排回填压脚、开采推进的分步开采方法。该法不仅保障了生产安全,还大大节省了滑坡处理工作量。该方法简单、实效、可行。本文具有很好的参考和借鉴价值。

The open pit slope landslide is the most common environmental geological problems,the author takes the coal mine in Hulun Buir as an example,in view of the open pit slope landslide problem of coal,a new method is proposed,which is to set aside coal pillar,normal mining,strip cleaning,strip mining,fill in the inner row,and step by step. This method not only ensures the production safety,but also saves the amount of treatment of landslide. This method is simple,practical and feasible. This paper has a good reference and reference value.
