The Conditions of insiturock-burst were probed into from rocks, rock mass structure, in-situ stress, hydrological conditions, engineering design and construction factors.
Bottom hole pressure and the models of considered 3d crack propagation model insiturock mechanics parameters, have made the assessment of situ rock mechanics parameters more realistic.
Thus, the stress value of insiturockin any position given can be determined and the model of distribution regularity of insiturock stress field of the mining area can be established...
