摘要
瓦斯抽放是治理煤矿瓦斯灾害的治本措施。目前的高位抽放巷多为岩巷 ,施工成本高。高位煤巷抽放瓦斯的方法在郑煤集团公司裴沟煤矿得到了成功的应用 ,有效地解决了瓦斯超限问题 ,保证了安全高产稳产 ,井下采煤工作面的工作环境也得到了。高位煤巷抽放瓦斯是三软煤层综放工作面治理瓦斯的又一成功举措 ,对相似条件矿区安全状况和工作环境的改善以及经济效益的提高具有重要的借鉴意义。
Gas suction is a fundamental measure to control gas.At present,most high-level suction tunnels are driven in rock stratum and cost much.Suction in coal tunnel is successfully carried out in Peigou Coal Mine,Zhengzhou Coal Mining Group Corp.Ltd.The gas is controlled so that the high output is ensured,and the circumstance of the working face is also improved.Gas suction in high-level coal tunnel is a new way to control gas in three soft coal seam in fully mechanized coal caving mining face.It has great importance to improve safety state and working circumstance as well as to raise economical benefit in mining area with similar conditions.
