晋北煤业5-103工作面走向空巷充填技术应用研究

Study on the application of goaf filling technology for 5-103 working face in jinbei coal industry

以晋北煤业5-103工作面过空巷为研究背景,经过对工作面过空巷期间充填体作用机理及参数的确定,进行了水灰比值为6:1的高水材料充填作业,通过对支架工作阻力和窥视孔效果分析,高水充填作业对巷道围岩变形和回采工作的顺利进行提供了保障。

taking Shanxi Province coal 5-103 working face through alley as the research background,after filling mechanism during the course of a working face through alley and determination of parameters for the water cement ratio of 6:1 high water material packing operation,by analyzing the effect of support working resistance and peephole,high water filling operation on the progress of the surrounding rock deformation of roadway and stope.
