| Abstract: | The outlines of the ninth panel in the south of Duerping coal mine and No.73902 working face were introduced.The stability of No.2 coal pillar in the upper contiguous seams was theoretical analyzed,and the layouts of roadways for No.3 coal seam in the lower contiguous seams were described,namely internal misaligned layout,alternate exterior entry layout and overlapping layout.The superiority of overlapping layout was pointed out via the comparison.The measurement of strata pressure showed that this kind of ... |
