October 12, Erdos - At Bayan Gol Coal mine, Shandong Energy Zibo Mining Group, people had been working hard to make sure all logistic problems underground can be solved within 20 minutes.
The mine newly purchased 14 transport vehicles, 9 of which were used to form mobile underground material station. All units could pre-order the required materials and equipment on the intranet, and have them delivered on spot, saving both man-hour and motor-hour.
Similar system had been applied to moving personnel. In the past the mine used a bus system that moves in certain routes and transport miners in a centralized mode, with every stop 500 meters apart. This system had been proven ineffective to send personnel to the more remote location in time. So the remaining 5 newly purchased vehicles were assigned to the underground teams to ensure that the farthest construction site could be reached within 20 minutes.In July, the personnel and material transport efficiency was increased by 12% and 16%.
