卸压开采抽采瓦斯理论,是我国部分煤矿在长期的生产实践中设计出煤体松动卸压的开采方案,解决了低透气性煤层难开采的问题,实现煤与瓦斯共采的科学构想。通过对解放煤层与瓦斯同采技术相关问题研究,分析了煤层与瓦斯共采技术的理论支持,提出了适合我国煤层瓦斯抽取的技术。
The theory of pressure relief mining and drainage of gas is a mining scheme designed by some coal mines in the long-term production practice to loosen and relieve the pressure of coal. It solves the problem of difficult exploitation of coal seam with low permeability and realizes the scientific concept of co-mining coal and gas. Through the research on the issues related to the coal mining technology with the liberated coal seam, the theoretical support of coal seam and gas co-mining technology is analyzed, and the technology suitable for coal seam gas extraction in China is proposed.
