摘要
对经坊煤矿X8-16陷落柱部署钻孔进行导水性探查,结合水文地质条件对陷落柱的发育规律进行分析,对其突水危险性进行分析评价,采用模糊数学法对陷落柱通过可行性进行了论证。结果表明,X8-16陷落柱存在较大奥灰突水危险,直接通过易引发矿井突水。根据评价结果提出了防隔水煤(岩)柱留设以及治理的防治水措施。
The water inrush risk of the collapsed column in Jingfang Coal Mine is analyzed and evaluated in this paper through the water conductivity exploration of the X8-16 collapsed column in this area,and by analyzing the development law of the collapsed column under the local hydrogeological conditions.Fuzzy mathematics was adopted here to demonstrate the feasibility of passing through the collapsed column.The results have shown that there is a great risk of Ordovician limestone water inrush in X8-16 collapsed column and it is easy to cause mine water inrush by directly passing through this collapsed column.According to the evaluation results,the water control measures for preventing water-proof coal(rock)pillar retention and treatment are put forward.
