Research Of Theory And Applications For Bursting Liability

Because of the social development requires the development of mining tools, There are many coal mines in China began deep mining. Mine pressure mine power caused by mining. So, it is very important to Research the impact of steep seam bias theory and application. In this paper article is based were collected from Daoqing mine measured data and mechanical laboratory experimental data, combined with theoretical analysis,study and Numerical simulation, research for The impact of steep seam bias theory and application by reality of daoqing Mine.Get Daoqing coal mine of the physical and mechanical parameters of rock by the laboratory and field testing. Provide true and reliable data of Numerical simulation and theoretical calculation, provide the conditions for Follow-up research work and the future of the mine for the related research work.Put forward the impact of steep seam bias theory by different coal seams dip to the overlying strata activities numerical simulation and analytical model established by the theoretical calculation. Coal and rock deformation by external force and the reasons for sudden destruction is not only a strength issue, the stability of deformation is not enough and the loss of stability issues, produces coal seam parallel to the direction of displacement. Seam roof obliquity greater the smaller the axial compression deformation. So we can find that steeply inclined coal seam deformation and damage to the roof of the main lateral bending. Bump formation process is a quasi-static place before the unstable equilibrium shift to another stable equilibrium state of the process of dynamic instability.Get damage time of coal and rock elastic energy index, peak gathered in front of the deformation energy, post-peak deformation energy gathering,uniaxial compressive strength. proposed seven measures to combat the impact of ground pressure To ensure mine safety in production. According to daoqing mine geological conditions and coal seam occurrence conditions, dynamic phenomena presented the basic principles of prevention and control of dynamical phenomena of the integrated technology.
