Study on the failure law of overlying rock under coal seam in close distance coal seam and feasibility discrimination of upward mining
Abstract Upward mining of close-distance coal seams is technically challenging due to the complex nature of overburden failure and the potential hazards associated with water and gas. This study assesses the feasibility of mining the 4–3 seam above the 4–4 seam at the Hongliulin Coal Mine using a co...
