Abstract EN
The results of the interaction between coal failure and mining pressure field evolution during mining are presented.
Not only the mechanical model of stope and its relative structure division, but also the failure and behavior characteristic of coal body under different mining stages are built and demonstrated.
Namely, the breaking arch and stress arch which influence the mining area are quantified calculated.
A systematic method of stress field distribution is worked out.
All this indicates that the pore distribution of coal body with different compressed volume has fractal character; it appears to be the linear relationship between propagation range of internal stress field and compressed volume of coal body and nonlinear relationship between the range of outburst coal mass and the number of pores which is influenced by mining pressure.
The results provide theory reference for the research on the range of mining-induced stress and broken coal wall.
