编制巷道稳定性和煤岩突出的预报时,对评估煤系地层的变形状态有着头等重要的意义。多道地震法可有效地发现在岩层自然赋存条件下决定岩体应力状态的变形的分布规律。这样,可以把大范围内获得的测量弹性特性的结果同声学测井和岩芯试样测量数据相比较。研究顿巴
The preparation of roadway stability and coal-rock outburst prediction is of paramount importance in assessing the deformation status of coal measures. The multi-channel seismic method can effectively find out the distribution of deformation that determines the stress state of rock mass under the natural occurrence of rock strata. In this way, the results obtained over a wide range of measured elastic properties can be compared to acoustic and core sample measurements. Study Dunbar
