Here, we quantify the effect of coal mine closure on terrestrial water storage (TWS) in China using satellite data and a staggered difference-in-differences approach.
Due to their abundant water and space resources, closed/abandoned mines can be innovatively developed for pumped storage energy, thereby extending the economic lifespan of mining
To examine its environmental performance, we performed a life cycle assessment (LCA) of a typical PHES plant in Liaoning, China, and compared with new energy

In the heart of China, a groundbreaking study is transforming the way we think about abandoned mine shafts, turning them into potential goldmines for renewable energy
In order to solve the potential safety hazards, waste of space resources and energy reserve safety caused by the abandoned open-pit pits in China, a new model for comprehensive utilization of
The "Energy Storage No. 1" project utilizes the caverns of an abandoned salt mine, reaching up to 600 meters of depth, as its gas storage
<p indent="0mm">Mining plays a crucial role in human society, encapsulated by the saying, "Everything we use is either grown or mined." However, once resources are depleted, most
Analysis of GRACE satellite data suggests that coal mine closures in China between 2014 and 2019 significantly increased terrestrial water storage due to the cessation of dewatering procedures and reduced industrial water usage.
The underground space resources of abandoned coal mines in China are quite abundant, and the research and development of underground space energy storage technology in coal mines have many benefits.
Generally, the roadway groups and goafs of abandoned mines can be rehabilitated as water-storage space for UPSPS instead of drilling another underground reservoir, which is the cheapest and possibly the most efficient method . The main advantages of using abandoned coal mines' space for water storage can be summarized as follows:
Closed/abandoned mines have impacted the economy, society and environment to varying degrees. However, China contains many coal mines with complex geological conditions and phased shutdown plans, and research on the development and utilization of abandoned mines is lacking.
In China, the concept of “secondary development” is not strong in abandoned mines. Most mines use “closed” and “backfill” to enclose the backfill roadway, which not only wastes a lot of underground space, but also brings great challenges to the subsequent mining work.
However, the efficiency of gas storage established in China is low, and its safety, stability, overburden subsidence prediction, and real-time monitoring of surrounding rock performance need to be urgently developed.
