| Abstract: | This peper carried out the numerical simulation of mine pressure law in mechanized coal face 702 of Da an-shan in Beijing mining bureau,obtaining the drop and destory law of directing roof and old roof of the coal face.This result was compered with physical simulation result, the conclusion was aimest equal. It offered a research method for mine pressure study for similar mining area. |
