摘要
随着我国能源产业结构调整,越来越多不符合国家要求的矿井被关闭,导致我国闭坑矿井数量迅速增加,矿井闭坑后产生的老空水,会对周围矿井生产造成威胁。以淮北刘东煤矿为研究对象,使用Visual Modflow软件对矿井闭坑后的水位回升进行了预测,以此为周边矿井安全生产提供依据和保障。结果表明:随着时间的推移,闭坑矿井内的水位会不断上升,深部较快,浅部较慢,并且得出了闭坑矿井水位变化趋势,矿井回灌时间约为240 d。研究结果也为相似地质条件的矿井防治老空水提供参考。
With the adjustment of China's energy industry structure,more and more mines that do not meet the national requirements are closed,resulting in a rapid increase in the number of closed mines in China.The old empty water generated after the mine closure will pose a threat to the production of surrounding mines.Taking Huaibei Liudong Coal Mine as the research object,Visual Modflow software is used to predict the water level rise after the mine is closed,so as to provide basis and guarantee for the safety production of surrounding mines.The results show that with the passage of time,the water level in the closed mine will continue to rise,faster in the deep and slower in the shallow,and the change trend of the water level in the closed mine is obtained.The mine recharge time is about 240 d.The research results also provide a reference for the prevention and control of goaf water in mines with similar geological conditions.
