In early December last year, two Jinantuo UQ-25 underground dump trucks were sent from the Daye base to the Xitieshan project department. As of May 28 this year, they had been in operation for more than 170 days, with excellent ore production results and low spare parts consumption. Achieve better economic benefits.

   The Xitieshan Mining Area is located in the hinterland of the Qaidam Basin. The mining area is on a plateau with an altitude of 3,100 meters. It has a typical continental desert climate, with year-round drought and little rain, windy and cold weather, long sunshine hours, and strong solar radiation. The comprehensive operating environment for equipment operation is extremely challenging, placing higher requirements on the reliability of underground dump trucks.

   Jinantuo UQ-25 underground dump truck is mainly responsible for transporting excavated waste rock from the middle section of 2222 to the surface in the Xitieshan Project Department. The longest running distance of the entire journey is 10 kilometers, which is basically uphill with heavy loads and long-distance downhill. The power system and wet braking system of the dump truck are most tested on site.

   The Xitieshan Project Department has used dry brake dump trucks in the past and has never used wet brake trucks. How to use the UQ-25 wet brake dump truck in plateau, alpine and long-distance uphill and downhill conditions? This has become a difficult problem facing the Xitieshan Project Department. The project department used the magic weapon "Mining 4.0" to strictly follow the requirements, conduct strict on-the-job training for equipment operators, and supervise and manage operators in accordance with operating procedures. Strictly implement the equipment maintenance plan.

   Since the operation of these two pieces of equipment in accordance with the requirements of "Mining 4.0", the total ore output has been: 24,840 tons and 30,360 tons respectively, the operating hours have been: 1,213 hours and 1,342 hours, and the kilometers have been: 13,560 kilometers and 14,583 kilometers respectively. The actual The utilization rates reached 45.9% and 50.8% respectively. During the return visit of Jinantuo service personnel, they found that the color of the hydraulic oil was normal and the maintenance was in place.

   Mechanical equipment is known as the management saying "the key lies in its use and the focus is on maintenance". Whether a piece of equipment can maintain good operation for a long time is inseparable from standardized operation and careful maintenance. The Xitieshan Project Department strictly follows the company's "Mining 4.0" requirements for training, use and maintenance of the equipment, and conscientiously implements the equipment management "cleaning, lubrication and The eight-character policy of ", fastening and inspection" has enabled the Jinantuo UQ-25 underground dump truck to have a low equipment failure rate for up to half a year of operation, with reliable equipment operation and good performance of the equipment. In order to thank the Xitieshan Project Department for caring for Hubei Jincheng Chengxin’s rental equipment and to encourage further equipment operation and maintenance work, the project department will be awarded a special reward of 10,000 yuan as an encouragement.
