Abstract: In order to realize an automation,intensification and modernization of the mine production,according to the mine production automation status of China Ping mei Shenma Energy & chemical Group,the paper discovered and studied the effective mode of the comprehensive automation study and construction in the mines of the gr oup and provided a construction plan of the mine comprehensive automation system integrated with the main coal flow system of the mine production and transportation,sa fety protection system and production support system as well as the safety production information management. The paper analyzed the three key technologies of mine inf ormation perception,mine information transmission and mine information processing and introduced the comprehensive digital network platform of the exchange,transmissi on and processing for the voice,data,image,pictures, dispatching and other comprehensive informations and the construction of each production automation system in the m ine. With the well comprehensive automation system of the group class mines established,management and control integration was realized and the production safety,oper ation efficiency and management and control efficiency were improved.
