摘要
依据煤矿老空区空间分布特性,对形成老空水的聚水空间、水源及通道等影响因素探讨分析。根据老空区形成的空间结构不同,采用不同的方法计算评价老空区积水量大小,分析其积水过程特点。对老空水的酸性演化过程、水质变化机理及其影响因素综合分析。针对老空区水酸性特性,探讨老空水处置技术,为煤矿老空水资源的处置利用提供新的思路。
According to the spatial distribution characteristics of the old goal in coal mine, the formation conditions of the old goaf water including water storage space, water-filled source, water- filled channel are analyzed. According tO the different space structure formed by the old goaf, different methods are used to calculate and evaluate the amount of water in the area, The formation process, water quality change mechanism and the influencing factors of acid and old water are analyzed comprehensively. For acidic water features in the old goaf area, this paper discusses the old empty water disposal technology, which provides a new way of thinking for the disposal and utilization of old water resources in coal mines.
