| Abstract: | Yujialiang Coal Mine in Shendong coal mining area carry on coal mining in #4-3coal seam and #4-2 coal seam,which are contiguous coal seams.On the basis of the establishment of a FLAC numerical model,a study is carried out on the impact of the face gob area in #4-2 coal seam on the coal face in #4-3 coal seam and the pattern of strata behaviours in the face in #4-3 coal seam.Out of the analysis,the extent of influence of the rock pressure on the face in 4-3 coal seam and the pattern of vertical stress change... |
| Keywords: | contiguous coal seam coal mining strata behaviours vertical stress impact of mining Yujialiang Coal Mine |
