Research on the development of a monitoring method to the loading model on rock transporting trucks at open-cast coal mines of Vinacomin by an equivalent model in the laboratory MSc. Le Ba Phuc, Eng. Do Van Trieu - Vinacomin – Institute of Mining Science and Technology Abstract: In order to monitor the implementation of the loading model of the excavator on trucks at the open-pit coal mines of Vinacomin to improve the utilization coefficient of mass and tonnage of the vehicle, and to optimize the performance of trucks, it is necessary to conduct the laboratory research on the truck body model, equivalent materials and the scanning method by 3D lazer on the ground. In order to complete the monitoring method to the loading model, as a basis for deploying the test results at the Coc Sau coal mine site and the wide application of the research results at the opencast coal mines of Vinacomin. |
