The numerical simulation of the behavior law of mine pressure in Lean Coal Seam
Abstract：Based on the condition of Guan Yin Shan Mine. We built a numerical model for lean and soft roof and floor coal seam by using the software FLAC3D to numerically study the stressdistribution and roof and floor muster. According to the simulation results that the first weighting interval of the coal face is about 20m. We study the vertical deformation and stress distribution a- long the coal face toward and inclined when the working face impelling to 100m,. On the mining pressure control has a certain reference value.
