Abstract: Combined with the actual situation of Jinda Coal Mine after the merger and reorganization, the geological structure, coal seam occurrence, coal seam thickness and hardness, coal seam structure, roof and floor conditions, etc. of the mine are analyzed, and the 10105 working face is finally determined to be more suitable for fully mechanized top coal caving mining. The technological parameters of fully mechanized top coal caving in 10105 working face are studied, including shearer cutting height and mining-caving ratio, caving step and shearer cutting depth, initial caving step, caving method, end caving and end caving. The results show that fully mechanized top-coal caving mining is more conducive to the safe and efficient mining of the mine, is conducive to improving the recovery of coal resources, can provide a reference for similar occurrence of coal seam mining methods.
