应用错层位巷道布置提高综放初采回收率的研究

Research on layout of dislocated strata gateway applied to improve initial mining recovery rate of fully mechanized top coal caving mining

根据错层位巷道布置采煤法初采期间的顶板状态,分析影响初采期间顶煤回收率的主要因素,并与实际工程应用中的实测数据进行对比,总结出应用错层位巷道布置采煤法提高初采期间顶煤回收率的机理。

According to the roof status in the initial mining period of the coal mining with the gateway layout in the dislocated strata,the paper analyzed the main factors affected to the top coal recovery rate in the initial mining period.In comparison with the site measured data applied in the actual project,the paper summarized the mechanism for the application of the mining method with the gateway layout in the dislocated strata to improve the top coal recovery rate in the initial mining period.
