补东回风巷揭煤安全技术措施

Study on safety technology of uncovering coal in East return air roadway

阳煤五矿补东回风巷现掌头岩性为陷落柱,以砂质泥岩、细粒砂岩为主,含少量煤屑。根据地质部门预测预报,施工20m将揭露15~#煤。本文从加强组织领导、通风瓦斯管理等方面对补东回风巷揭煤安全技术进行研究,确保巷道揭煤工作的顺利进行,杜绝瓦斯事故。

During driving East return air roadway of Yangquan coal NO.5,met the collapse column that the lithology is sandy mudstone,fine-grained sandstone,containing a small amount of cinder.According to the geological department prediction,after construction20m,will uncover15#coal.In this paper,from the aspects of strengthening the organization and leadership,ventilation and gas management,the safety technology of uncovering the coal in the East return air lane is studied to ensure the smooth operation of the roadway uncovering coal and prevent gas accidents.
