Distinct element analysis on coal movement law and failure mechanism during mechanized top-coal caving in steep thick seam

Civil and Environmental Engineering School, University of Science and Technology Beijing, Beijing 100083, China

摘要: 應用UDEC2D計算程序,對某煤礦大傾角厚煤層綜采放頂煤的空間效應及其放煤機理進行了數值模擬,揭示了在綜放開采過程中采場覆巖與頂煤的移動規律及相應的應力場、破壞場的變化特征,并對控頂區項煤的變形破壞特征及直接頂的離層跨落步距進行了分析.

Abstract: By using UDEC2D technique, this paper analyzed coal and rock movement laws, the deformation and failure characteristics of coal and the major principal stress in the process of top-coal caving in steep thick seam. The failure mechanism of coal and the movement trend of rock on the top-coal caving working face were discussed. The results showed agreement with the field conditions, which is of important theoretical meaning to direct the practice in the similar engineering.
