摘要
借助显微镜和扫描电镜等对煤样的观察 ,阐述了突出煤的煤岩特征及微观破坏痕迹 ,对组分和微结构、微构造进行了定量分析 ,并论述了微观特征对突出的影响 ,为具有突出倾向的煤层提供了预报参数。
Based on analysis results of coal samples with microscopic and scanning electron microscopic research,it is described that the petrographic characteristics and microscopic depredation of burst coal.The quantitative analysis on the componens and microcosmic structures of burst coal is conducted.The influence of microcosmic characteristics on the burst is discussed.It provides the consults to forecast the burst of the coal seams with burst tendency.
