The rule of methane effusion of full-mechanized top coal caving in thick,hard and high-gas seam

摘要：

According to the gas observational data,the gas spatiotemporal distributions are analyzed in full-mechanized top coal caving in thick,hard and high-gas seams.The factors influencing gas effusion are researched and the rules of gas effusion under the spatial condition are deduced.The research results can be the base of forecasting gas effusion and gas controlling under this special condition.
