很多矿区和实验室的调查研究表明:在各种不同的采矿条件下,采场支架与顶板岩石的相互作用都是作为某种应力-应变状态用复杂的运动学和力的定律来描述的。阐明采掘区附近的围岩中这种特有的应力-应变状态的产生条件是地质力学的一个重要问题。 对液压支架与围岩相互作用的典型系统给以解析的描述,进而在此基础上研究出一种可以在新的技术水平上进行液压支架设计的理论方法是十分必要的。 解析的研究能使我们发现支架与围岩相互作用的最近似的一般规律。对这种相互作用过程进行解析的研究目前落后于实验工作。造成这种事实的原因不仅是由于有关因素的复杂性和多样性,同时也是因为必须把围岩和液压支架作为一个整体来加以描述。
Investigations by many mines and laboratories have shown that the interaction of stope support with roof rock under a variety of mining conditions is described by a complex law of kinematics and forces as a stress-strain state. It is an important issue of geomechanics to clarify the condition of this unique stress-strain state in the surrounding rock around the mining area. Based on the description of the typical system of the interaction between the hydraulic support and the surrounding rock, it is necessary to develop a theoretical method that can design the hydraulic support at the new technical level. The analytical study enables us to find the most general rule of the interaction between the support and the surrounding rock. The analysis of this interaction process is currently lagging behind experimental work. The reason for this is due not only to the complexity and diversity of the factors involved, but also to the fact that the surrounding rock and hydraulic support must be described as a whole.
