Study on Overlying Strata Movement and Surface Subsidence of Coal Workfaces with Karst Aquifer Water
Publikováno v:
Mathematics, Vol 10, Iss 2, p 169 (2022)
The overlying strata layers of coal workfaces with karst aquifer water normally causes serious safety problems due to the precipitation, drainage and water inrush, such as a wide range and long term of surface subsidence. In this study, by taking 10,
