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 re- lease 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 short- comings, 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.
