| Abstract: | This paper, using the method of plane finite-element analysis, calculated and analysed the distribution of floor stress in the working faces and studied the law of deformation and break of floor strata. It explained the forming mechanism of the breaking zone and the influence of mining on water irruption in the floor strata. The paper, based on the results comprehensively observed to the floor strata in situ, discussed the relationship between the breaking depth and the geological conditions of the working faces. The results obtained from the study, can give some reference to the safe mining in coal seams above water-bearing measures |
