高瓦斯易燃煤层综放面瓦斯治理技术研究

A study of mine gas control in fully mechanized long wall face in highly gaseous inflammable coal seams

介绍了阳泉矿区在高瓦斯易燃煤层采用综放开采工艺条件下 ,利用“U +I”型通风方式 ,配合顶板走向高抽巷抽放上邻近层瓦斯综合治理的技术 ,使工作面实现年产 2 0 0万t的生产能力的试验情况以及瓦斯治理效果。

This paper introduces the use of 'U + I' ventilation mode in fully mechanized long wall face in highly gaseous and inflammable coal seams. The paper also introduces the use of this technology to help reach the high production rate of 2.0Mt/a and gas controls.
