Coal Geology & Exploration
In view of the low utilization rate of closed mine resources and the increasing demand for power and energy storage in China, the pumped storage technology of abandoned mine is an effective means to realize the secondary development and utilization of resources and enhance the peak sheaving capacity of power grid. Based on the working principle and development status of pumped storage power plants using the abandoned mines, it was proposed to build the semi-underground and full-underground pumped storage power plants using the abandoned mines in the nine provinces of Yellow River Basin. By considering the influence factors of space, …

Coal Geology & Exploration
In promoting the achievement of the carbon peak and carbon neutrality goals in China, the development of residual coalbed methane resources in abandoned mines is of important practical significance. However, the development of the residual coalbed methane is characterized by its secondary dynamic reservoir formation after disturbed under original geological conditions. Therefore, the related literature at home and abroad in recent years is summarized as follows. (1) The disturbed area of the overburden and floor in coal seam mining can be divided into the gas conduction fracture zone, pressure relief zone and non-desorption zone. The influence range of coal seam …
