鹤煤(集团)公司六矿为单一煤层开采的高突矿井。随着矿井开采深度的增加,瓦斯含量越来越大,为提高抽放效果,进行了井下水力压裂强化抽放,提高防突效果技术研究。通过增大抽放半径,提高了抽放效果,解决了高瓦斯低透气性突出煤层掘进工作面防突问题。
Hebi Coal (Group) Company VI is a single seam mining high-profile mine. With the increase of mining depth, the gas content is more and more large. In order to improve the drainage effect, the technology of underground gas fracturing to enhance drainage and improve the effect of preventing outburst is studied. By increasing the drainage radius, the drainage effect is improved, and the problems of outburst prevention in the driving face of the advanced coal seam with high gas permeability and low permeability are solved.
