Research on the inherent mechanism of rock mass deformation of oil
Since the pyrolysis temperature of oil shale is mainly 400–500 °C, the actual temperature of in-situ mining of oil shale usually does not exceed 600 °C, so the predetermined temperatures are selected as 150 °C, 300 °C, 400 °C, 500 °C and 600 °C. Additionally, oil shale at room temperature is used for comparison experiments.
