Prediction of Gas Emission in High Gas Mines and Application of Extraction Technology
In order to effectively improve the gas extraction effect,taking the gas geological conditions of Jinpu Mountain Mine as the background,theoretical analysis and on-site experimental methods were used to predict the gas emission rate of the mine,and the gas extraction technology was optimized and applied.According to the extraction effect,the average gas extraction volume of high-level drilling is 7.69 m3/min,and the gas concentration in the upper corner does not exceed 0.5%,indicating that after optimizing the gas extraction technology,it can meet the daily production needs of the mine.
