摘要
以某矿井下-690未开挖巷道的煤岩体作为研究对象,利用实验模拟了3个煤岩体试样在动力压缩破坏条件下的应变特征,借助计算机图像相关匹配技术,结合煤岩体的自燃散斑标志点,得到了最大拉应变情况下3个煤岩体试样的最先破坏位置,并测量了破坏程度。
Taking a mine roadway excavation in coal and rock mass without-690 as the research object, using strain features of the experimental simulation three coal rock specimen under dynamic compressive condition, with the aid of computer image correlation matching technology, combined with the spontaneous combustion of coal rock speckle point, the maximum tensile strain case three coal rock specimen the first damage location, damage degree and measurement.
