摘要
为了保证野川煤矿三采区辅助运输巷的安全快速掘进,杜绝水害事故发生,通过技术研究,决定对辅助运输巷过原柳树底煤矿老采空破坏区段采用超前钻探施工,共计放水量为4543 m^(3)。巷道在后期掘进过程中未出现顶板及两帮淋水现象,保证了巷道安全快速掘进,取得了显著的应用成效。
To ensure the safe and rapid excavation and avoid water disaster in auxiliary transportation roadway of No.3 mining area in Yechuan Colliery,the author proposes the advanced drilling construction in failure zone of goaf,which can avoid water spray in roof and two sides with water flowage of 4543 m^(3) and guarantee the safe and rapid excavation with remarkable application effects.
