摘　　要：充填开采是解放“三下”压煤,防止地表沉陷,实现矿井煤炭资源可持续开发的有效途径。以山东东山古城煤矿为背景,对建筑物下压煤采取膏体充填置换开采的可行性进行了分析,并提出优化措施。研究结果表明:膏体置换开采充填项目的实施,可以有效解决古城煤矿建筑物下压煤的开采问题,缓解煤炭资源紧张,降低地表沉降影响,提高煤矿经济效益;所提出的优化措施为类似矿井提供技术参考。Filling mining is an effective way to liberate the‘three unders’coal,prevent surface subsidence and realize the sustainable development of coal resources.Based on the background of Dongshan Gucheng Coal Mine in Shandong Province,the feasibility of paste filling replacement mining for coal under buildings is analyzed,and the optimization measures are put forward.The results show that the implementation of paste replacement mining filling project can effectively solve the problem of coal mining under buildings in Gucheng Coal Mine,alleviate the shortage of coal resources,reduce the impact of surface subsidence,and improve the economic benefits of coal mines.The proposed optimization measures provide technical reference for similar mines.
