摘要
大同煤田燕子山煤矿煤层开采面临底板含水层水害问题,随着煤层开采深度的增加,底板水害问题越来越突出。结合大同煤田燕子山煤矿地质条件、水文地质条件等现有资料对燕子山煤矿研究煤层底板含水层突水脆弱特征加以分析,应用脆弱性指数法,得出燕子山矿底板突水脆弱性评价分区,并结合含水层突水脆弱性评价分区提出了矿井防治水对策措施与建议。
This research mainly aimd at the floor aquifer water hazard problem in Yanzishan Mine of Datong Coalfield.With the increase of mining depth, the floor water hazard problem became more and more prominent. Based on the analysis of the geological and hydrogeological conditions of Yanzishan Mine in Datong Coalfield, combined with the research results and experience, the vulnerability characteristics of water inrush from coal seam floor aquifer in Yanzishan Coal Mine were analyzed by scientific and advanced methods. At the same time, the vulnerability index method was applied to obtain the vulnerability of water inrush from Yanzishan Mine floor. Based on the evaluation zoning and the vulnerability assessment zoning of aquifer water inrush, the countermeasures and suggestions for mine water control were put forward.
