岩体状态控制是包括旨在保持巷道稳定在内的所采取的全部措施。通过控制岩石应力-应变状态和提高岩体强度的办法以利用岩体本身的承载能力,已成为一种新的研究方向。如果对巷道周围岩体中力学过程的发展性质和规模具有切合实际的认识,在此情况下才能保证所采取的措施收到效果。由于在试验一生产中对岩体的变形和破坏进行了观测,所以可以获得具体条件下的这些认识。但是,已知的检测方法复杂、费力而效果又不好。
Rock status control includes all measures taken to stabilize the roadway. It has been a new research direction to control the bearing capacity of rock mass by controlling the stress-strain state and increasing the strength of rock mass. If there is a realistic understanding of the nature and scale of the development of the mechanical processes in the rock mass surrounding the roadway, it is only in this case that the measures taken can be effective. These observations under specific conditions can be obtained due to the observation of the deformation and failure of the rock mass during the production of the test. However, the known detection methods are complex, laborious and ineffective.
