高瓦斯矿井瓦斯抽采系统优化研究

Study on Optimization of Gas Drainage System of High Gassy Mine Shaft

为了实现煤与瓦斯高效共采,对山西某矿现有瓦斯抽采系统进行了优化设计,设计效果能实现工作面回采时瓦斯不超限,地面瓦斯抽采系统抽采浓度80%时间稳定在32%以上,瓦斯抽采效率达到52%。

To realize the high-efficient exploitation of coal and gas, the existing gas drainage system at a coal mine in Shanxi Province was optimized design. The aim of the design is to make the gas not overrun when mining the working face, the drainage concentration is stable,which is above 32% ,during the 80% period in the gas drainage system on the ground,and the gas drainage efficiency reaches 52%.
