Gu Dazhao, academician of Chinese Academy of engineering and general manager of science and Technology Development Department of Shenhua Group, led the team to inspect the mine explosion-proof electric trackless rubber tyred transport vehicle jointly developed by Shendong Coal Group (hereinafter referred to as Shendong group) and China Aerospace Sanjiang group (hereinafter referred to as Sanjiang group) in Daliuta mining area, Praise for the product: it not only injects zero pollution green mining elements into the deep coal seam, but also sets off the revolution of green intelligence, safety and efficiency of coal underground auxiliary transportation vehicles.

In March 2015, Shendong group and Sanjiang group implemented the spirit of the strategic cooperation agreement between China Shenhua Group and China Aerospace Science and industry group, and jointly carried out innovative research on pure green and environment-friendly explosion-proof electric trackless rubber tyred transport vehicles such as mining 5-ton material truck, 19 person transport vehicle and 7 person command vehicle by using Aerospace innovative technology, In order to build a "zero emission green roadway", a substantial step has been taken.

At present, the green environment-friendly 5-ton explosion-proof pure electric trackless rubber tyred material transport vehicle (referred to as material vehicle) and the pure green environment-friendly 19 person explosion-proof electric trackless rubber tyred personnel vehicle (referred to as personnel vehicle) have been put into industrial operation in Daliuta mining area of Shendong group. With the strong advantages of "zero emission, low energy consumption, low noise, low fault, long service life and easy maintenance", the two types of mine trucks solve the shortcomings of existing mine explosion-proof diesel trucks, such as "high pollution, high fuel consumption, high noise, high fault, low service life and difficult maintenance", reduce the requirements of mine ventilation, improve the mine working environment, and enable underground workers to breathe the same air as the ground, The transformation of "black collar" to "white collar" of coal miners will become a reality. The successful development of the product is not only well received by the front-line staff, but also has achieved good economic and social benefits.

It is reported that the material vehicle and personnel vehicle are specially designed and developed in accordance with the special special vehicle in combination with the special harsh working conditions underground. The product adopts many advanced technologies, such as independent suspension, timely four-wheel independent motor drive directly to the wheel edge, timely compound safety braking of high-efficiency electric braking and mechanical braking, active intelligent monitoring and command system for multiple health parameters of the whole vehicle, etc. At present, 6 patents have been accepted and 6 technical papers on mine electric vehicle design have been completed. Up to now, five material trucks have been running for more than 24000 km in Daliuta mining area of Shendong group, and they are in good condition. The full load driving range of underground comprehensive working condition is more than 90 km, and the attendance rate is as high as 94%. The personnel car has been running in Daliuta mine of Shendong group for more than 2 months, and has been running for more than 2500 km. It is in good condition. The full load driving range of underground comprehensive working condition is more than 80 km, and the attendance rate is more than 95%. The energy consumption cost per 100 km of the two types of electric vehicles is only about 13% of that of the same type of diesel vehicles.

At present, according to the problems existing in the emergency rescue and front-line operation in the mining area and the requirements put forward by the users, Shendong group and Sanjiang group are making use of the existing mature mining explosion-proof electric vehicle technology platform to work together on the 12 person mining explosion-proof electric emergency rescue vehicle, mining 5-ton explosion-proof electric multi-function material transport vehicle, mining 100 ton explosion-proof electric shovel plate transport vehicle, mining 1-ton explosion-proof electric shovel plate transport vehicle In the early stage, detailed investigation and demonstration were carried out for the innovative projects such as mine 3 cubic explosion-proof electric concrete truck and mine electric vehicle intelligent health diagnosis management and command digital platform system, so as to build the world's first "zero emission green mining roadway" for Shenhua Group to truly practice the five development concepts of "innovation, coordination, green, opening and sharing", Create a world-class clean energy supplier and make more positive contributions.
