摘要
介绍了山阳煤矿多煤层开采副井井筒揭煤时的具体实施方法。在施工中采用了预测预报、瓦斯排放、震动放炮等综合防治突出措施,并加强组织管理,有效地消除了煤层突出的危险性,使井筒顺利穿过4~#、5~#煤层,取得了良好的经济效益和社会效益,为澄合矿区此类矿井施工作业积累了经验。
The specific implementation method for coal uncovering of auxiliary shaft in multi-seam mining of Shanyang coal mine was introduced.The comprehensive measures of preventing and controlling outburst were used in construction like forecast,gas drainage,volley shotfiring,etc.,and the organization and management were strengthened.The risk of coal seam outburst was eliminated effectively,and the shaft crossed smoothly through the 4~#,5~# coal seam,good economic efficiency and social benefits were realized,and all of this accumulated experiences for similar shaft construction in Cheneghe mining area.
