文章以深孔预裂爆破技术理论为基础,对参数设计中的钻孔布置、爆破及工艺设备等具体参数进行了详细的分析,并结合现场进行了试验研究。结果表明:深孔预裂爆破技术的应用,在一定范围使突出煤层卸压,提高了煤层透气性,使高压瓦斯加速排放,减少了突出势能,有效防治了煤与瓦斯突出。 Based on the theory of deep-hole presplitting blasting, the paper detailedly analyzed the concrete parameters of drilling layout, blasting and process equipment in the parameter design, and carried out experimental research with the site. The results show that the application of deep-hole presplitting blasting technology can relieve the pressure of the outburst coal seam in a certain range, improve the gas permeability of the coal seam, accelerate the discharge of high-pressure gas, reduce the prominent potential energy and effectively prevent the outburst of coal and gas.
