倾斜煤层放煤工艺参数的选择分析

Selection and Analysis of Process Parameters for Inclined Coal Seam Coal Mining

倾斜煤层在我国具有较大得到储量,如何对倾斜煤层进行有效的开采,提高开采效果对我国煤炭资源的使用具有重要的影响。针对倾斜煤层放煤工艺参数的选择设置,采用PFC仿真模拟的形式进行分析。结果表明,随着放煤步距的增加,顶煤的放出量呈逐渐增加的趋势,经过分析,选择合理的放煤参数为采高4m时进行两采一放的放煤方式。

Tilted coal seams have significant reserves in China.Effective mining of inclined coal seams and improving mining efficiency have important implications for the utilization of coal resources in China.The selection and setting of coal mining process parameters for inclined coal seams are analyzed using PFC simulation.The results showed that with the increase of coal release step distance,the amount of top coal released gradually increased.After analysis,a reasonable coal release parameter was selected as the coal release method of two mines and one release when the mining height was 4 m.
