As the deep mining environment becomes increasingly complex,the problems of high ground stress and passing through fracture zones were analyzed and studied in order to achieve safe and efficient deep mining blasting construction.The implicit and explicit coupling analysis program in the finite element analysis software ANSYS-LS/DYNA was used to simulate the fractured rock mass under bidirectional equal pressure and bidirectional unequal pressure.Then,this program was used to study blasting excavation in the special condition of fractured rock mass with weak plane under high ground stress.The research results show that during the blasting mining process of deep fractured rock mass,the tensile stress of the unit gradually decreases with the increase of the confining pressure,but the compressive stress of the unit does not increase significantly in an isobaric in-situ stress field in all directions.At the same time,the compressive stress of the element near the right side of the crack reaches the peak value of the survey line,and the compressive stress increases with the confining pressure.In anisotropic stress field environment,the tensile stress of the survey line in the hole and crack area reaches its peak value when the lateral pressure coefficient is 1.33.Therefore,in the process of deep mining and blasting,attention should be paid to the in-situ stress field in the fracture zone including cracks,which has a significant impact on the safe and efficient implementation of blasting excavation.
