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。
Based on the spatial distribution characteristics of the old empty coal mines, the influential factors such as the water space, the water source and the passageway of the old empty water are discussed and analyzed. According to the different spatial structure formed by the old empty area, different methods were used to evaluate the amount of water accumulated in the old empty area, and the characteristics of the water accumulation process were analyzed. A comprehensive analysis of the acidic evolution process of old empty water, the mechanism of water quality changes and its influencing factors. Aiming at the characteristics of water and acidity in the old empty area, the old empty water disposal technology is discussed to provide a new idea for disposal and utilization of old empty water resources in coal mines.
