ABSTRACT The mine uses a large number of major production vehicles such as large machinery, electricity, and liquid. In coal production, these equipments are responsible for mining coal, decentralizing mine production materials, lifting mining production workers and production equipment. It is the main way to connect uphole and downhole. It is an essential equipment for the normal production of mines. This paper takes a research background of a comprehensive coal mine project group integrating coal, electric power and coal chemical industry. In view of the fact that the current mine lifting electronic control system cannot meet the actual production needs, the reform plan and implementation of the mine lifting electronic control system have been fully studied. According to the existing situation of Lingxin Mine, and extensively investigating the development status of relevant research at home and abroad, the electronic control equipment is technically transformed. The main research work is as follows: The overall plan for the transformation of mine hoisting electronic control system is analyzed. The equipment overview was analyzed and the transformation function is introduced. Based on this, a transformation plan is designed. The transformation of the mine lifting machinery system was studied. Including transportation equipment selection and replacement device modification. Based on the current situation of the existing electronic control system, the reform idea isput forward, and the transformation plan is given to improve the safety and reliability of the system and reduce the noise and room temperature. The device speed adjustment is continuous and smooth, which can reduce the impact on the machine and the power grid, and ensure the safe operation of the system. The mine lifting control system is transformed, and the high-voltage variable frequency control is modified in combination with the transformation requirements. This not only improves operational efficiency, but also enhances operational safety. Finally, the modified system is applied in the field. The results show that the mine electric control system reform research in this paper can optimize coal mine production equipment, simplify production, reduce operation and maintenance costs, and improve production efficiency.
