残采矿井相邻采区水力联系分析及防治水措施

Analysis of Hydraulic Connection in Two Adjacent Districts in a Mine Working Residual Coal and Water Control Measures

分析了高庄矿残采期间采空区积水运移规律,证实了闭坑前矿井采空区整体上成为水源良好的通道,相邻采区的老空水对生产采区产生补给作用,增加生产采区水文地质复杂程度,严重影响剩余资源复采、回收。为了保证安全生产,提出截水方案,将影响生产四采区最大的二采区水堵截,取得了良好效果。

A study is made of the law governing the flow of the accumulated water in the goafs during the residual coal mining period.The study shows that the goafs are a favorable water flow passage and the water in the goafs constitutes a source for recharge to the mining districts,thus adding to the complexity of hydrogeological conditions in mining districts and difficulties of mining operations.For ensuring mining safety,measures are adopted to block off the water in the goafs of the 2nd mining district that is believed to exert a most adverse effect on the 4th district.The measures taken have met a positive result.
