Abstract: In order to improve the automation level and efficiency of coal mining in the 8127 comprehensive mining face of the C2# layer, based on the geological conditions of coal mining in the 8127 comprehensive mining face of the C2# layer and combined with the main comprehensive mining equipment used, the intelligent transformation of the comprehensive mining equipment in the 8127 comprehensive mining face of the C2# layer was carried out, and the engineering application verification was carried out. The verification results showed that after the intelligent transformation, the monthly yield of the 8127 comprehensive mining face of the C2# layer could be increased by 47%, and the personnel could be reduced by 44.4%, achieving the goal of reducing personnel and increasing efficiency. This study can provide reference for the intelligent transformation of comprehensive mining faces under similar working conditions.
