Abstract
The PCG Mine #8 already practice methane drainage are considered to drain their seam gases and reduce atmospheric emissions of methane, After studying the methane drainage system and Visualisation and analysing of mine ventilation data.real-time monitoring of ventilation and methane drainage at the longwall face B15-13330. Analysis have shown that gas drainage in this face accounts for 38.3% of the total gas release and the ventilation air methane takes up 61.7%. On the other hand, ventilation air methane from the longwall face B15-13330 represents 72.2% of methane in the whole district. Sealing and design of the drainage wells used can improve this efficiency as will be discussed. The dynamic information of mine gas geology is obtained, and how to improve this efficiency is also discussed. Finally, the implementation of coal mine drainage system is optimised.
