摘要
哈拉沟煤矿通过建立地面钻孔输送砼硐室、井下煤矸置换、矿井水综合利用和变频驱动等措施,以及应用工作面调斜开采技术、切顶卸压沿空留巷技术和450 m超长综采工作面开采技术,提高了矿井煤炭回采率,推动了煤矿节能减排工作,践行着低碳绿色的发展理念。
In Halagou Coal Mine,by taking the measures such as constructing conveying concrete chamber of ground drilling,implementing underground coal gangue replacement,comprehensive utilization of mine water and frequency conversion drive,popularizing advanced technologies of adjusted inclined mining,gob side entry retaining of roof cut and pressure relief and 450 m super-long fully-mechanized mining face,the coal recovery rate was improved,the coal mine energy saving and emission reduction work was promoted and the low carbon green development concept was practiced.
