矿山井下矸石充填技术实践研究

Practical research on filling technology of gangue in underground mine

本文对矿井下矸石充填提出背景、现状及工艺进行分析,并以花山矿每年产生7.0万m3矸石为例,通过矿井下矸石充填与矸石升井费用进行对比,得出矸石充填每年可节约费用559.2万元,并产生巨大的社会效益。

This paper analyzes the background, status quo and process of coal mine gangue filling, and takes the annual production of 70 million m3 of coal gangue in huashan mine as an example. By comparing the cost of coal mine gangue filling with that of coal gangue hoisting, it is concluded that coal gangue filling can save 5.592 million yuan per year and bring huge social benefits.
