Research on Filling Mining Technology for Large Dip Coal Seams
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.
