摘　　要：为解决中煤平朔集团有限公司井工一矿因地质条件复杂,地表建筑、地下管线密集,常规开采易导致地表沉陷和水资源破坏问题,通过分析矿区地层特征和水文地质条件,提出了基于风积沙高水膨胀材料的充填开采技术,采用FLAC^(3D)数值模拟方法,对不同采高、充填材料和工艺参数进行了优化设计,确定适用于连采和综采工作面的充填策略,具体包括材料配比、充填步距和工艺流程。当充填开采等价采高为0.35 m时,数值模拟显示地表下沉系数为0.27,有效控制了地表沉陷,保护了地面建筑、地下水和管道设施。研究表明,风积沙高水膨胀材料充填技术在经济性和环境保护方面表现出显著优势,为类似复杂地质条件下的煤矿绿色开采提供了有效的技术支持。In order to solve the problem of surface subsidence and water resources destruction can be easily caused by conventional mining because of complex geological conditions,dense surface buildings and underground pipelines in Jinggong No.1 Mine of China Coal Pingshuo Group Co.,Ltd.,through analyzing the stratigraphic characteristics and hydrogeological conditions of the mining area,the filling mining technology based on aeolian sand and high water expansion materials is proposed,and the FLAC^(3D) numerical simulation method is adopted to optimize and design different mining heights,filling materials and process parameters,and determine the filling strategies suitable for continuous mining and fully mechanized mining faces,including material ratio,filling step distance and process flow.When the equivalent mining height of filling mining is 0.35 m,numerical simulation shows that the surface subsidence coefficient is 0.27,effectively controlling surface subsidence and protecting surface buildings,groundwater,and pipeline facilities.The research shows that the aeolian sand high water expansion material filling technology has significant advantages in terms of economy and environmental protection,providing effective technical support for green mining in coal mines under similar complex geological conditions.
