摘要
大倾角煤层开采作业中,若不对采空区进行适当充填,极易发生岩层沉陷.就矸石滑移充填开采技术展开研究,建立顶板力学模型,进行受力分析,并在山西省某煤矿 3203 工作面开展现场矿压监测,得出矸石滑移充填非均匀性、矿压分区性、来压时间时序性等结论.
Abstract
In the mining operation of high angle coal seams,if the goaf is not properly filled,it is very easy to cause rock subsidence.Research was conducted on the technology of gangue sliding and filling mining,establishing a roof mechanical model,conducting stress analysis,and conducting on-site mine pressure monitoring at the 3203 working face of a coal mine in Shanxi Province.The conclusions were drawn on the non-uniformity of gangue sliding and filling,the zoning of mine pressure,and the temporal sequence of pressure.
