【摘要】 选择平顶山矿区不同煤层３０个煤样进行电子顺磁共振实验和煤的最大反射率测试．结果表明，构造煤的顺磁共振谱图线宽、自由基浓度和最大反射率值增高．在实验基础上进一步探讨了构造煤的动力变质作用和自由基浓度在煤和瓦斯突出预测中的作用．更多还原

【Abstract】 Thirty Pingdingshan coal samples from different coal seams have been studied by means of electron paramagnetic resonance, and the maximum reflectance has been measured. The research results show that the linewidth, radical densities and maximum reflectance of disturbed coals are increased. The dynamic metamorphism of disturbed coals and the effect of radical density on coal gas outburst prediction are discussed.更多还原
