中国煤矿区域性瓦斯治理技术的发展

随着中国煤矿开采深度的增加，煤与瓦斯突出矿井和突出煤层的数量不断增加，以保护层开采及卸压瓦斯抽采技术和强化预抽煤层瓦斯技术为代表的区域性瓦斯治理技术，得到了长足发展．通过中国煤矿煤与瓦斯突出灾害严重性分析，阐述了煤与瓦斯突出灾害区域性治理的必要性，在此基础上分析了中国区域性瓦斯治理技术的发展过程、保护层开采及卸压瓦斯抽采技术和强化预抽煤层瓦斯技术的发展现状，还总结了淮南、淮北、阳泉和沈阳4个矿区区域性瓦斯治理技术的应用实例，最后对中国区域性瓦斯治理技术的应用前景进行了展望．

Development of Regional Gas Control Technology for Chinese Coalmines

With the increase of mining depth in Chinese coalmines, the quantity of outburst mines and outburst coal seams keeps increasing. Regional gas control technologies, such as protecting seam exploitation, pressure-relief gas extraction, and strengthening gas extraction in advance, have gotten a great development. In this paper, we analyzed the ponderance of outburst disasters in Chinese coalmines, expatiates the necessity of regional gas control. Based on these, the developing process of regional gas control technology and the status of the technique of protecting seam exploitation, pressure-relief gas extraction, and strengthening gas extraction in advance were also analyzed. In addition, we also summarized the application prospect of the regional gas control in Huainan, Huaibei, Yangquan, and Shenyang diggings. Finally, the application foreground of regional gas control technology in China was predicted.
