Space-sky-surface integrated monitoring system for overburden migration regularity in shallow-buried high-intensity mining

High-intensity coal mining activities in China’s western mining area are damaging fragile ecological environments. The key to coordinating ecological protection and coal mining is to understand the law of overlying strata migration in high-intensity mining. However, it is difficult for conventional monitoring methods to efficiently monitor overburden movement in high-intensity mining areas in real time. In this paper, a space-sky-surface (3S)...
