机械模拟试验台在研究支架——围岩关系中的应用

THE APPLICATION OF THE MECHANICAL SIMULATION DESK IN STUDYING THE RELATIONSHIP BETWEEN FACE SUPPORTS AND SURROUNDING

本文采用机械模拟的方法探讨采场支架—围岩的作用关系。对支架工作阻力与支承压力分布及支架工作阻力与顶板位态之间的关系进行了分析,得出支架—围岩的关系曲线,即顶板位态曲线,由双曲线和抛物线两部分组成。用“机械模拟”的方法来研究支架—围岩的作用关系是一个简单、有效的研究手段。

In this paper, the method of the mechanical simulation has been applied to analyse the reaction relationship between face supports and surrounding rocks, and the relationship between the working resistance of supports and distribution of the abutment pressure as well as the roof. position. The results indicate that the overall relationship curve bctween suppots resistance and surrounding rocks was composed of two parts: hyperbolic and parabolic ones. It was concluded that the mechanical simulation method is a simple effective mean to study the reaction relationship between face supports and surrounding rocks
