摘要
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。
No.6 mine of Hebi Coal Company is one mined on single coal seam with severe outburst risk.As the mining depth increases gradually,the gas content becomes higher and higher.In order to improve the effect of gas drainage,hydrofracturing and intensified gas drainage are carried out.With the increase in drainage radius,the drainage effect improves,so the anti-outburst is solved on tunneling faces of outburst risk coal seams with high gas content and low permeability of air.
