coal and gas outburst is the direct reason of mine accidents, so it is very important and meaningful to predict condition of methane outburst accurately and timely.
the creep mathematical model provides a basis for establishing a comprehensive index of coal and methane outburst possibility.
含瓦斯煤蠕变方程的导出为建立广义的突出危险综合指标提供了基础。
bp algorithm and rols(recursive orthogonal least square)algorithm based on radical basic function were applied to predict methane outburst while merits and faults of the two algorithms were compared.
