摘要
充分发挥综采放顶煤开采的技术优势,治理综放工作面瓦斯尤为重要。在介绍阳泉矿区15号煤层及邻近煤岩层瓦斯赋存基础上,分析了综放工作面瓦斯来源和特征,提出了不同条件下瓦斯治理方法及治理措施,并对其治理效果进行了分析。实践应用表明,走向高抽巷与内错尾巷共用系统排放工作面瓦斯,效果最为显著。
In order to develop advantages of fully-mechanized top caving mining,gas control in the fully-mechanized top caving working face is very important. Based on introducing No. 15 coal seam in Yangquan mining region and gas occurrence in nearby coal seam and rock seam, the paper analysed the gas resource and gas content in fully-mechanized top caving face. It present the gas control methods and measurement, and analysed the gas control effects, too. Practice application shows it is best that the shared system of direction high pumping and inside end roadway for gas emission.
