摘要
相似材料模拟是科学实验的一种,这是人们探讨和认识地压规律的途径之一,按矿山实际原型,按一定比例缩小做成模型,然后在模型中开挖巷道模拟采场工作,观察模型的变形、位移、破坏和岩层移动等情况。据此分析,推测原型中所发生的情况。
The similar material simulation is a kind of scientific experiment, this is one of ways that people discusses and understands geostatic pressure rules. The similar material simulation means that according to the mine actual prototype, we make models in certain proportion, then excavates the tunnel in the model to simulate stope works, then observe distortion, displacement, destruction situation and rock layer displacement, and so on. Then according to analysed results, we extrapolate actual situation in practical environment.
