Analysis on Key Problems of Winter Operation in Alpine-cold Open-pit Mine

Abstract

Through the analysis of winter operation problems in the alpine-cold open pit mine in Mengdong area, the technical and economic feasibility of adopting advanced peeling and winter peeling scheme is demonstrated. For the open-pit mining and transportation equipment in the alpine-cold region, the solutions for the scooping and sticking materials, the freezing of the brake circuit, and the sticking of the compartments are often proposed in winter operations. The anti-freeze system of the belt conveyor is composed of the cold resistant tape, the cleaning device, the antifreeze film, the heating device and the anti-freeze roller. Some safety production organization measures for blasting operations, mining operations, and semi-continuous systems in winter construction operations were proposed. It can effectively help the open pit mines in the alpine-cold regions to reduce equipment failures and ensure efficient operation in winter safety production.
