摘要
9104工作面在回采期间揭露陷落柱,开采条件急剧恶化,严重影响矿井的正常安全生产,本文在矿山采用电法勘探、现场钻探的方法对陷落柱的分布范围以及围岩性质进行了探测的基础上提出了相应的治理措施,工程监测结果表明该治理措施对工作面的治理效果较好,涌水量大幅减小。
The collapse column was exposed during the mining period in 9104 working face,which seriously affected the normal safety production of the mine.In this paper,the method of electromagnetic exploration and on-site drilling was used to explore the distribution range of the collapse column and the nature of the surrounding rock,and the corresponding treatment measures were put forward on this basis,which proves that the treatment measures have a good effect on the working face and the water inflow is greatly reduced.
