Slope hoisting and crushing system for deep open-pit mine

Abstract

The invention discloses a slope hoisting and crushing system for a deep open-pit mine, which comprises rails laid at the top of a deep open pit and on a slope, and a winch arranged at the top of the pit. Steel structure box beams are combined and mounted on the slope of the pit; the rails on the slope are laid on the steel structure box beams; tramcars are arranged on the rails; the winch is connected with the tramcars by a hoisting sheave guide device and a steel wire rope group; a dumping platform is arranged on a deep working step of the pit; the tramcars on the deep working step of the pit receive ore on the dumping platform through an automobile; a crushing station receiving tank and a coarse crushing machine are arranged at the top of the pit and located below the rails; the tramcar is hoisted to the top of the pit by the winch and unloads the ore into the crushing station receiving tank; and the ore is conveyed to a dressing plant or a refuse dump by a belt conveyor after crushed by the coarse crushing machine. The system has the characteristics of low mining and rock stripping cost, flexibility, convenience, small hoisting pull, greenness, environmental protection, high efficiency, energy conservation, good safety and reliability, large application scope and the like.

Description

technical field [0001] The invention relates to a complete set of semi-continuous mining system equipment for large-scale deep concave open-pit mines, especially suitable for a deep concave open-pit mine slope lifting and crushing system with an annual output of 5-40 million tons, and can be widely used in mine mining, transportation and crushing technology field. Background technique [0002] In the 1940s and 1950s, the mining vehicle hoisting and transportation technology for deep concave open-pit mines was proposed. The mining vehicle filled with ore rocks was pulled from the bottom of the deep concave open-pit stope along the track to the top of the stope by a winch. , and then transported by mining trucks to the crushing workshop far away from the stope for crushing. Since the self-weight of the vehicle is about 45% of the material weight, the traction of the winch and the bearing capacity of the roadbed are additionally increased; in addition, the slope track for lift...
