Description

technical field [0001] The invention relates to the technical field of rock mechanics, in particular to a test device for simulating the stability of roadway surrounding rock in a deep high-temperature environment, and a test method using the device. Background technique [0002] In the process of coal mining, with the continuous increase of mining depth and mining intensity, especially in the mining under complex geological conditions, the problems encountered in the mining process continue to increase. With the increase of mine mining depth, the stability of the surrounding rock of the deep roadway is affected by the high temperature and high humidity environment. Rock stability is an important research method in this field. [0003] At present, in the study of roadway stability, there are many methods of theoretical analysis and numerical calculation, but the above research methods idealize the actual conditions on site, ignore many environmental factors, and the analysi...
