Abstract
The article presents the results of modeling the stress–strain state of the carboniferous massif in the lava 48 – 8 of the Yerunakovskaya – VIII mine branch and the effect of the speed of movement of the treatment face on the development of emergency situations in the lava working out the formation 48. The problem was solved by the finite element method taking into account the physico–mechanical properties of coal and the host rocks of the roof and soil of the formation. Based on the results of modeling and experience of cleaning operations on reservoir 48, the minimum speed of lava movement was found, at which no domes are formed in the cleaning space and no emergency situations occur.
Keywords
