摘要
采用理论和实验相结合的方法 ,对煤的电性参数随煤的物理力学性质、吸附瓦斯、承受应力的变化关系和变化幅度进行了研究 ,得出了煤的电性参数随决定煤与瓦斯突出的 3个因素之间变化的定量关系 。
with the theoretical and practical combined theory, the paper studied the varied relationship and varied degree of coal electric parameters with the coal physical mechanism property; absorbed gas and stressing of coal. The results of the study showed that the coal electric parameters were varied with the three factors of the coal and gas outburst. Therefore, the results can provide the theoretical foundations to build a relationship model between the coal electric magnetic wave reducing field and the gas outburst danger.
