The Application of Hydraulic Fracturing Outburst Prevention Measures

摘要：

Hydraulic fracturing measure can effectively improve the coal seam permeability and improve seam gas drainage peatlands in low permeability coal. Meanwhile it can change the physical and mechanical properties of coal and increase coal plastic. This measure can effectively prevent rockburst, having the role of preventing gas and coal outburst.After hydraulic fracturing measure, coal peak support stress is reduced,the peak support stress position transfers to the coal deeply. It achieves good effect of coal gas control after the application to the 24080 working face in the tenth coal mine of Pingdingshan coal group company. The effectiveness of the measures is confirmed in the scene.
