围岩移动是地压的表现形式,它一方面受到各种因素的影响(包括支架的作用)而另一方面仅影响其他的因素。尤其对于支架来说常常是支架承压与折损的基本原因(当顶板为坚固的整体岩石时)。目前我国有很多煤矿的坑木消耗费用几占工作面总成本的50%以上。因此,研究围岩移功的规律改善顶板管理工作从而降低坑木消耗与成本,是当前采矿工业的迫切任务之一。 Surrounding rock movement is a manifestation of earth pressure, which is influenced by various factors (including the role of scaffolding) on ​​the one hand and other factors on the other hand. In particular, it is often the basic cause for the support to be stressed and broken (when the roof is a solid, solid rock). At present, there are many pit coal consumption costs in our country account for more than 50% of the total cost of the face. Therefore, it is one of the urgent tasks of the current mining industry to study the law of the surrouding of the surrounding rock and improve the roof management to reduce the consumption and cost of the pit.
