Study on the effect of outburst coal s gas seepage under ground stress

摘要：

Based on the typical coal and gas outburst mine-Datong mine in Songzao, the effect of outburst coal s gas seepage under ground stress is simulated by the development of self-pressure triaxial permeame ter. The seepage velocity-stress curves of outburst coal are obtained by the experiment. The process equa tions of seepage velocity-axial stress and seepage velocity-confining pressure are built.

关键词： ground stress seepage velocity triazial permeameter
