Jinchuan Hydropower Station is located in Jinchuan County and Malkang City, Aba Tibetan and Qiang Autonomous Prefecture, Sichuan Province. It has been listed as a key development project of energy construction supported by the state to support the economic and social development of Tibetan areas in Qinghai and other provinces, and a key construction project in the "14th Five-Year Plan" energy development plan of Sichuan Province. It is also a key project of the group's "Four Heavy and One Important. The total installed capacity of the power station is 860 MW. The dam type is a concrete face rockfill dam. The maximum dam height is 112 meters, the crest width is 10 meters, the crest length is 275.8 meters, and the crest elevation is 2258 meters. The dam body is located on a deep overburden with a maximum depth of 65 meters. The dam body is divided into upstream blanket area, cover area, cushion area, special cushion area, transition area, main rockfill area, filter area, downstream rockfill area, downstream slope protection area and other structures, with a total filling volume of about 4.56 million square meters.
