Abstract

Thermally stimulated rock failure has been actively studied for over 30 years for solving both fundamental and applied problems. At the same time, there are features that make it difficult to obtain information on the development of thermal compared to mechanical damage. The article discusses three main problems: the small number of recorded acoustic emission pulses, the difference in thermal conditions during heating and cooling, and the high level of interference from conventional heating control systems. The article analyzes ways to solve these problems and proposes and develops an improved laboratory setup and methods for studying thermally stimulated rock failure.

研究岩石中热声发射记忆效应的设备和方法

摘要

为了解决基本问题和应用问题，热激岩石破坏已经进行了30多年的积极研究。同时，与机械损伤相比，有些特征使获得热发展信息变得困难。本文讨论了三个主要问题：记录的声发射脉冲数量少，加热和冷却期间的热条件差异以及常规加热控制系统的高干扰水平。本文分析了解决这些问题的方法，并提出并开发了一种改进的实验室设置和研究热激岩石破坏的方法。
