Analysis on Effective Radius of Borehole for Gas Drainage

摘要：

For the work of gas drainage, the important thing is to find reasonable effective radius gas drainage borehole. In the paper, based on the analysis of the gas seepage model of coal in the surrounding gas drainage borehole, gas pressure distribution rule in the surrounding of borehole is put forward. Effective pressure-released radius of gas drainage borehole is analyzed theoretically. From the application in Chengzhuang mine, analysis result in theory is in accordance with engineering practice.
