无烟煤型煤和原煤的渗透特性对比研究
Comparative Study of the Permeability Characteristics Between Anthracite Coal and Raw Coal
摘要
Abstract
Through constructing permeability experimental platform,it selected the representative samples of anthracite coal and raw coal in Jiaozuo Mining Area,studied the differences between briquettes and raw coal in coal body permeability experiment.At the same time,it studied permeability effect differences of different confining pressure and gas pressure for briquettes and raw coal under the single condition of changing confining pressure or gas pressure;When confining pressure and gas pressure were changeless,under the condition of applying axial stress load,it compared and analyzed the permeability changes of briquettes and raw coal in the process of stress change.The results showed that the permeability change trend of briquettes between confining pressure and gas pressure was similar,but had big difference in the process of stress load,the selection of coal samples had great effects on the result in the permeability experiment.关键词
