CO_2致裂增透技术在煤矿的应用

Application of CO_2 Crack Ventilate Technology in Coal Mine

针对贵州省安顺地区某煤矿生产过程中煤层瓦斯涌出量大,瓦斯抽采难等问题,特提出应用CO_2致裂增透技术提高煤层透气性,实现煤矿安全高效生产。通过透气性系数、流量衰减系数、抽采浓度、抽采纯量及瓦斯含量的对比分析,最终实现抽采钻孔优化方案。

For Guizhou Anshun district in theproduction of a certain coal mine coal seam gas emission,gas extraction difficult problems, especially put forward the application of CO2 crack ventilate technology to improve coal seam permeability, achieve efficient production of coal mine safety. Through the comparative analysis of air permeability coefficient,flow attenuation coefficient,extraction concentration,pure quantity and gas content, the optimization scheme of extraction drilling is finally realized.
