分布式计算在闭坑矿井汇水过程的应用Application of Distributed Computation in Closed Mine Water Confluence Process

摘要(Abstract):
随着国家煤炭资源的战略整合和小型闭坑矿井的数量增加,地下采空空间内地下水充填及含水层水位回弹已成为临近生产矿井突水的巨大隐患。以徐州庞庄煤矿闭坑案例为研究对象,考虑井下采区水平高低不一,根据老空区积水量和可容纳水量,结合各采区高程的差异性和老空水的分布流向,先将矿井的汇水过程进行分布式分析,再进行整合分析,得到如下结论:-520m和-620m水平优先汇水,-820m水平最后汇水;5年后老空水水位回弹至-380m水平临界值;相邻矿井预留防水煤(岩)柱早已达到临界承载压力,在长时间浸泡环境下隔水效果锐减,需要通过合理控制汇水水量和回弹水位达到有效遏制突水危害的目的。
