上部煤层采空区积水对下组煤层开采的影响

Influence of Upper Coal Goaf Water for Lower Group Coal Seam Mining

通过加强矿井防治水工作的管理,防止和减少水害事故的发生,特别是上部煤层采空积水在没有查清情况下盲目开采下组煤层,使上部采空积水溃入井下造成突发性水害。介绍了上部采空积水是今后下组煤开采主要研究的对象。以中兴煤矿为例,对可能形成的水害隐患进行了分析,论述了矿井防治水采取的措施及探放水实践。

Through strengthening the management of prevention and control mine water, prevents and reduces the occurrence of water inrush accidents, especially the upper coal goal water without gleaning cases blind exploits lower group coal seam, makes the upper goaf water burst into downhole cause sudden of water disasters. Introduces the upper goal water is the main research object in mining lower group coal in future. Takes Zhongxing coal mine as an example, the water hazard of possible formation is analyzed. The prevention and control measures of mine water and the practices of water detection and water release are discussed.
