基于极薄保护层开采的深部煤层绿色开采综合技术

Comprehensive technology of deep coal seam green mining based on extremely thin protective layer mining

随着煤炭开采进入深部,煤与瓦斯突出对安全生产的危害更为严重。保护层开采是目前广泛使用地、最为行之有效的煤与瓦斯突出防治措施。本文提出了一种基于极薄保护层开采和煤矸石回填的深部煤与瓦斯共采的绿色煤炭开采综合技术,并将其应用于平煤股份十二矿,提高了煤层瓦斯抽采率,减少了温室气体排放;煤矸石回填不仅提高了煤炭质量,减轻了运输系统负担,降低了煤炭开采后地面沉降。

As coal mining enters the deep,coal and gas outburst are more harmful to safe production.Protective layer mining is the most effective and effective coal and gas outburst prevention measure.This paper proposes a comprehensive technology of deep coal and gas mining based on ultra-thin protective layer mining and coal gangue backfilling,and applies it to Pingdingshan Coal Mine No.12,which improves coal seam gas drainage rate and reduces greenhouse gas emissions;coal gangue backfill not only improves the quality of coal,reduces the burden on the transportation system,and reduces land subsidence after coal mining.
