煤炭工业中新型注浆工艺的经济性分析

Economic Analysis of New Grouting Process in Coal Industry

首阳山煤业经过多年发展,采空区顶板存在一定的安全隐患。为保证回采工作的顺利开展,在掘进时既快速又安全地通过老巷,首阳山煤业探索了一种既经济又安全的现代化新工艺,通过使用新型注浆材料粉煤灰对巷道进行注浆充填加固,不仅提高了工作效率,还取得了多方的良好效益。实现了工作面顺利通过老巷,保障矿井的安全高效生产,提升了矿井生产整体的工业现代化水平。

The process of mine modernisation has been increasing,the mining depth has been increasing,and the consequent management of the mining hollow area has become part of the mine's key work.After years of development of Shouyangshan Coal Industry,there are certain safety hazards on the roof plate of the hollow area.In order to ensure the smooth development of mining work and to pass through the old roadway quickly and safely when digging,Shouyangshan Coal Industry explored a new modern technology which is both economical and safe,and used a new type of grouting material,fly ash,to grout and fill the roadway,which not only improved the working efficiency,but also achieved good benefits for many parties.
