During the period of the Sixth Five-Year Plan, the first sub-project of underground engineering of one of the key state scientific and technological projects under discussion was the technical symposium and the first result review meeting of the “Stability and Surrounding Rock Classification of Surrounding Rock Surrounding Caverns”. In 1985 Children from 27 to December 9 by the Ministry of Water Resources Kunming Survey and Design Institute hosted in Chengdu. Representatives and experts from relevant sectors attended the meeting. The meeting presented a total of 23 research reports and information, including the classification of surrounding rock underground hydraulic caverns, underground cavern stability of engineering geological research, classification of rock classification at home and abroad, the application of simple tests for the classification of rock
