Coal Mine Stope Surrounding Rock Stress Control Method and Applied Research
In the mining area roadway layout, mining technology, mining area and mining parameters and mining procedures, there will be some different coal mining plan to be possible to choose, In the mining process, some different mining plan will develop some different stope surrounding rock stress distribution and rock energy. A reasonable mining plan should avoid surrounding rock stress highly concentrated and mine disaster. In this paper, to control the stope surrounding rock stress highly concentrated as the goal, by numerical simulation, theoretical analysis and calculation methods, the authors analyzed the stope surrounding rock stress distribution under some different mining parameters and different mining plans, and the authors conducted yield pillar design and analysis under pressure arch theory, as well as using rock stress control methods, such as adjusting coalface and coal seam mining procedures or mining parameters to control surrounding rock stress highly concentrated, in order to reduce the risk of mine disasters. Practice shows that the stope surrounding rock stress control method results in the field of space with regional, with a long time, the degree of thoroughness and on high-risk conditions for the solution of the stope surrounding rock control provides a method of control and theoretical basis.
