前言目前松动圈理论在在底下空间的发展中已经普遍得到了人们的认可,特别是松动圈支护理论在煤炭工程和安全生产中起到了非常重要的作用,而松动圈是围岩普遍存在的物理形态,目前我国对于松动圈的物理理论的研究较少的,但是采用雷达勘测技术已经普遍的对围岩松动圈的研究有了一定的认识,本文针对此问题进行了详细的分析和探讨。 Foreword At present, the loose ring theory has been generally accepted by people in the development of the under space. In particular, the loose ring support theory plays a very important role in coal engineering and safety production, while the loose ring is widespread in the surrounding rock At present, there are few researches on the physics of loose ring in our country, but there is a general understanding of the research on the loose ring of surrounding rock by using the radar survey technique. In this paper, the problems are analyzed and discussed in detail.
