摘要
为了保证巷道安全快速掘进,解决上覆采空区、含水层、裂隙水等水患,韩家洼煤矿决定对22401运输顺槽掘进期间进行合理有效的超前钻探施工设计,同时为了保证探放水施工安全,对探放水施工期间钻场采取联合支护技术。通过实际应用效果来看,22401运输顺槽采取探放水施工设计后,巷道在后期掘进过程中未出现顶板及两帮淋水现象,取得显著应用成效。
In order to ensure the safe and rapid excavation of the roadway and to solve the water hazards such as overlying mining area,aquifer and fissure water,Hanjiawa coal mine decided to propose a reasonable and effective over-drilling construction design during the excavation of 22401 transport chute,and at the same time,to ensure the safety of water exploration and discharge construction,the joint support technology was adopted for the drilling field during water exploration and discharge construction.Through the practical application of the effect,22401 transport chute to take the water exploration construction design,the roadway in the later digging process did not appear in the roof and the two gang drenching phenomenon,achieved significant application results.
