哈拉沟煤矿节能减排及提高煤炭回采率技术

Overview of Energy Saving and Emission Reduction and Improving Coal Recovery Rate Technology of Halagou Coal Mine

文章阐述了哈拉沟煤矿开展节能减排、提高煤炭回采率工作中的一些做法,得出如下结论:输送砼硐室、井下煤矸置换、矿井水综合利用技术和变频电机技术等应用,推动了煤矿节能减排工作;调斜开采技术、切顶卸压沿空留巷技术和450m超长综采工作面开采技术等,提高了矿井煤炭回采率。

This article clarifies some practices about energy saving and emission reduction and improvingcoal recovery rate of Halagou Coal Mine,the result shows that the work of energy saving and emission re?duction in coal mine is promoted by the applications of conveying concrete chamber,coal gangue replace?ment, comprehensive utilization of mine water technology and frequency conversion motor technology. Thecoal recovery rate is improved by inclined mining technology,cutting roof and unloading pressure along thegoaf technology and 450m long fully mechanized mining face mining technology.
