Abstract:In order to reduce the degree of damage to the ecological environment during the development of mineral resources, and to realize the coordination of resource development and environmental protection, the establishment of a resource and environmental balance system is the only way to promote the high-quality green development of China’s mining enterprises. As an indispensable part of the green mine resources and environmental balance system, it is urgent to conduct an in-depth study of the water balance. This paper analyzes the water consumption and water extraction of mines, clarifies the definition of water balance, and establishes the relationship between water balance on this basis, proposes the corresponding formula for calculating the water balance, and at the same time, details the components, and puts forward suggestions and ideas to help realize and optimize the water balance, which will help China’s green mine to build comprehensively, and promote the transformation and upgrading of China’s mining enterprises.
