煤炭充填开采技术在济宁煤矿的应用

济宁市煤炭企业为安全高效开采煤炭资源，开展了煤炭充填开采技术研究，该技术的实施既释放了地下煤炭资源，提高资源回收率；又控制了土地塌陷，减少矸石占压，保护矿区生态环境，提高矿井开采安全保障程度，具有良好的经济效益和社会效益。但该技术还存在生产效率低、厚层煤充填效果不理想、不能满足大面积实施等一些问题，需要进一步完善提高。

Application of Coal Filling Mining Technology in Jining Coal Mine

In order to explore coal resource safely and efficiently,coal filing mining technology research has been carried out by coal enterprises in Jining city.The implementation of this technology can not only release underground coal resources,but also can improve resource recovery;control land subsidence,reduce the occupation of coal gangue,protect the ecological environment in mining areas,and improve safety level of underground mining.It has good economic and social benefits.But this technology still has some shortcomings,such as low production efficiency.This technology can not meet the demand of mining with large square.Thus,it should be further improved and perfected.
