在前面三讲叙述了关于岩石的基本性质和测试技术之后,我们可以应用这些知识来解决一个为大家所最关心的问题:岩崩的预报。对岩体破坏进行预测,就是通过调查研究以认识矿山岩体活动的客观规律,从而预估它的活动进程,作出科学的测预,为矿山生产建设服务。但是,关于这方面的工作,无论是国内外都还处在较幼稚的阶段上,还未形成系统的知 Having described the basic properties of rocks and testing techniques in the previous three passages, we can apply this knowledge to solve one of the problems most often of concern to us: the prediction of rock avalanches. The prediction of rock mass destruction is through the investigation and study to understand the objective law of mine rock mass activities, so as to predict the course of its activities, make scientific measurements and provide services for mine production and construction. However, work on this issue has not yet been systematically known, both at home and abroad, at a more naive stage
