Features of the stress field in the ore-bearing intrusions of the October and Talnakhskiy deposits, with taking into account the depth of the ore deposits and the formation of tectonic disturbances are considered. Analysis of tension underworked and overworked intrusion. The dependencies of stress field formation in the intrusion in the joint working out of intrusion ore deposits are obtained. Recommendations on joint working out of intrusion ore deposits Oktyabrskiy and Talnakhskiy deposits are given.
Consideration is given to the causes complicating the mining of shaftbottom pillar and protection of shaft lining. The analysis is given of the formation of stress-strain state of the protective pillar and its enclosing rocks. Practical recommendations are given for control of deformationand stresses in the shaftbottom mass during extraction of protective pillars in deep ore mines at Talnakh.
The reasons that complicate the process of elaboration dividing arrays of deep mines Talnakh. The analysis of the formation of stress-strain state dividing arrays during the development of treatment work. Practical advice on management strains and stresses in underworking Block structures dividing arrays.
Consideration is given to the causes complicating the mining of shaftbottom pillar and protection of shaft lining. The analysis is given to the formation of stress-strain state of the protective pillar and its enclosing rocks. Practical recommendations are given for control of deformation and stresses in the shaftbottom mass during extraction of protective pillars in deep ore mines at Talnakh.
The paper contains the results and analysis of the formation of stress-strain state in blocky structure enclosing the dividing mass. The regularities were established on the influence of blocky structure undermining on stress state of the floor of dividing mass. Recommendations are given for the safe mining in the dividing rock mass.
