Abstract

The invention discloses a road construction method for strip mine. The road construction method includes the steps of: firstly, clearing the soil materials below the road pressure surface; then, mixing the cleared soil materials with sand and performing stirring; and finally, refilling the road with the mixed and stirred mixture, and spreading a wearing layer on the top, and then conducting maintenance work. According to the road construction method for strip mine, sand is mixed in a single soil material to change the road material structure and enhance the material hardness, the road transportation quality is enhanced, and the integrated road bears more enormous upper pressure in the truck transportation process. And the difficulty that existing road construction methods are difficult to meet normal transportation operation of large mechanical equipment in strip mine can be overcome.

Description

technical field [0001] The invention relates to the field of open-pit mining, in particular to a road construction method for open-pit mines. Background technique [0002] At present, the main production process of domestic large, medium and small open-pit mines includes three stages of coal mining, transportation and discharge, and some open-pit mines include blasting. Under normal conditions, the transport road (soil road) can be used for vehicles to run after being leveled by a road leveler. [0003] However, with the increasing size of mine transportation equipment, the weight of goods carried by trucks is increasing, so the roads are gradually deformed due to the limit of bearing pressure, which eventually leads to the destruction of the roads, and the efficiency of truck transportation plummets. This situation is especially serious in geological soft mines. [0004] The information disclosed in this Background section is only for enhancing the understanding of the ge...
