安阳矿区低透气性煤层瓦斯抽采效果提升技术

Improvement Technology of Gas Drainage Effect for Low Permeability Coal Seams in Anyang Mining Area

随着开拓逐步延深,煤层透气性降低,瓦斯含量、瓦斯压力不断升高,突出灾害越来越严重。通过采取优化增透和封孔工艺、探索抽采负压与流量的关系、优化抽采系统等措施,提升低透气性煤层瓦斯抽采效果。对安阳矿区低透气性煤层瓦斯抽采效果提升技术的应用进行了探讨。

With the gradual deepening of the development,the permeability of the coal seam is reduced,the gas content and gas pressure are increasing,and the outburst disaster is becoming more and more serious.The effect of gas drainage in low permeability coal seams is improved by taking measures such as optimizing the process of increasing permeability and sealing holes,exploring the relation of negative pressure and flow,and optimizing the drainage system.This paper discussed the improvement technology of gas drainage effect for low permeability coal seams in Anyang mining area.
