oct 20, 2017 based on the boundary surfaces of bauxite deposit modelled by the two-dimensional biharmonic spline interpolation, it was ascertained that the fully mechanized longwall mining of bauxite is feasible in terms of lithological characteristics, orebed occurrence, physicalmechanical properties of orerock, faults, karst caves, permeable fissures, etc.bauxite primarily comprises minerals such as boehmite, gibbsite, hematite, goethite, ilmenite, and anatase. It is usually found near the surface of the terrain; hence, strip mining, a type of surface mining, is carried out. strip mining is the process of mining a layer of mineral by initially removing long strip of overlying rock and soil. then for the 1102 longwall mining panel in wachangping bauxite mine, the optimal cutting height of shearer ranges from 1.16 to 2.32 supplied from two 1.16-m-diameter cutting drums, which meets the
