| Abstract: | The paper analyzed gas pre-pumping of several holes enclosure in coal road of the #5103 area Meihe of the No. 2 mine. , through analysis on the application and comparing with the traditional pre-pumping, Testing result shows that the method has many advantages, such as：simple operation, short operating time, gas drainage works pretty good, safe and low cost and so on. The method can apply to the similar mine all can achieve the same higher Pre-pumping yields. |
