Abstract: The hydrogeological conditions of the Qianbei coalfield are complex, and karst water in the roof rock frequently disrupts mining operations, leading to frequent water inrush incidents. Taking the representative Longfeng Coal Mine as a case study, this paper analyzes the structural characteristics of the overlying roof strata. By calculating the stratum stretching rate, the theoretical development height of the water-conducting fracture zone is derived to be 51 meters. Numerical simulations were used to study t… Show more
