巷道超前钻探设计及安全技术探析

Analysis on advanced drilling design and safety technology of roadway

为掌握煤矿井下含水带的分布状况,避免巷道水害事故的发生,以司马煤业1303运巷为研究对象,设计实施了1303运巷在掘进期间的超前钻探工艺,提出了相应的安全技术措施,并对可能出现的涌水情况进行了排水系统与避灾路线设计,实践表明,超前钻探施工能够有效巷道水害隐患,降低突水事故发生的频率,安全效果显著。

In order to master the distribution of underground water cut zone of coal mine and avoid the occurrence of tunnel water damage ac-cident,the advance drilling technology of 1303 transportation roadway during excavation is designed and implemented,and the corresponding safety technical measures are put forward,taking Sima Coal Industry 1303 roadway as the research object,and the advance drilling technology of 1303 transportation roadway is designed and implemented,and the corresponding safety technical measures are put forward.The drainage system and disaster avoidance route are designed for the possible water inrush condition.The practice shows that the advance drilling con-struction can effectively reduce the frequency of water inrush accidents,and the safety effect is remarkable.
