| Abstract: | The opening stability in soft weak coal layer is important to the safe production in a mine. The time to produce damage deformation in surrounding rock and possible loosening area are obtained by analyzing in situ measurement of displacement in soft weak coal layer. The deformation regions are different in the roof, the floor and the two side of opening. The results from finite element analysis are basically identical with in situ measurement results, and some references are supplied for bolt shotcrete support design in soft weak coal layer opening. |
