摘要
针对龙固煤矿二号辅助运输大巷几个层位突涌水现象较为严重的问题,在巷道注浆堵水过程中提出了关键孔治理思想,制定了钻孔评价标准和关键孔的多因素层次优选方法。从材料消耗和堵水效果监测方面对关键孔的作用效果进行了评价。通过对钻孔的评价和优选,提高了钻孔的利用效率。
Aimed at the severe water inrush in many positions of No. 2 auxiliary main haul ageway in Longgu Coal Mine, the key borehole control was proposed for water plugged by grou ting into roadway and the evaluation criteria for boreholes and the multifactor optimizing method of key borehole were made. The effect of key borehole was evaluated according to the material consumption and the monitoring on water plugging effect. The utilization efficiency of borehole was enhanced through the evaluation and optimization of boreholes.
