前言在实验室研究矿山压力及岩层移动的规律,使用的方法一般有光弹性法,离心模型法,以及最近发展较为迅速的相似材料模型研究的方法。除此亦有把岩层看成单纯松散体而用砂子制成模型来研究岩层移动的,根据以上所列举研究方法的研究成果中可以知道实验室研究在矿山压力及岩层移动中占有相当重要的地位。最近我们实验室为了研究回采后岩层移动的情况及顶板垮落
Preface In the laboratory, the laws of mine pressure and rock movement are studied. The commonly used methods are the photoelastic method, centrifugal model method and the recently developed similar material model research method. In addition, the rock formation is also considered as a loose body and sandstone is used to study the movement of rock strata. According to the research results listed above, it is known that laboratory research occupies a very important position in mine pressure and rock movement . Recently, our laboratory in order to study the post-mining rock movement and roof collapse
