In the process of coal mining,the poor permeability of the coal seam in the excavation face results in poor extraction efficiency.To solve this problem,in practical operations,it is necessary to use CO_(2) gas phase fracturing and permeability enhancement technology to treat the working face based on reducing the outburst prevention index.This article takes a certain experiment as an example to explain in detail the drilling arrangement and application of fracturing technology,and analyzes the experimental results.After analysis,the application of CO_(2) gas phase fracturing and permeability enhancement technology can significantly improve the pumping effect,quickly reduce the outburst prevention index,and significantly reduce the time for reaching the pumping standard.Specific application practices are proposed to demonstrate that technology can play a role in preventing outburst in mining.
