On the basis of a simplified borehole log of Erunakovsky deposit, Kuznetsk coal basin, we designed a structural model of a rock mass containing two near coal beds. Here, we performed a numerical simulation of longwall mining of the 48th coal seam to study the features of the roof and floor fracturing. The simulation is performed in the framework of a continuous damage mechanics approach and a finite-difference method. We account explicitly for the gas fluid pressure by setting the stationary profile along the vertical axis which influences an effective shear strength of rocks. [ABSTRACT FROM AUTHOR] |
