According to Baikert staff, the mine hoisting equipment is the throat equipment for mine transportation. The mine hoisting wire rope is responsible for the function of linking the hoisting container to transport coal, ore, materials and personnel. Its reliability is directly related to the normal production of the mine and the life safety of personnel. Once the wire rope breaks, it will lead to a major accident of well destruction and death. Therefore, it is of great significance to accurately evaluate the safe service life of wire rope in service to ensure the safe operation of mine hoisting equipment.

According to the staff of Baikete, the mine hoisting equipment is the throat equipment for mine transportation. The mine hoisting wire rope is responsible for the function of linking the hoisting container to transport coal, ore, materials and personnel. Its reliability is directly related to the normal production of the mine. And the life safety of personnel, once it appearswire ropeThe fracture will lead to a major accident of well destruction and death. Therefore, it is of great significance to accurately evaluate the safe service life of wire rope in service to ensure the safe operation of mine hoisting equipment.

The hoisting wire rope is in the harsh environment of high temperature, high wind speed and acid and alkali erosion for a long time, and the water in the mine and the coal seam contain a large number of harmful ions that cause corrosion will cause electric corrosion on the metal surface of the wire rope, forming many corrosion pits on the surface and gradually deepening, becoming the source of stress concentration points and fatigue cracks. At the same time, corrosion will reduce the cross-sectional area of the wire rope and reduce the bearing capacity of the whole wire rope. Data show that corrosion will make the steel wire rope strength loss of more than 30%, some as high as 50%. However, at present, the research on steel wire rope corrosion at home and abroad mainly focuses on the protective effect of several hot-dip coatings on steel wire rope under seawater or atmospheric corrosion. Lin et al. found that the corrosion of the coating in 5% NaCl solution was carried out in the order of zinc-rich phase, aluminum-rich phase and intermetallic compound by means of dynamic potential polarization.

So the current mine wire rope corrosion accounted for more than half of the wire rope scrap. The later anti-corrosion lubrication of the wire rope can effectively alleviate the corrosion and effectively extend the service life of the wire rope. The choice of grease is the primary consideration of mine wire rope maintenance.
