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
The present invention relates to the semicontinuous mining system outfit of a kind of large-scale deep open pit, be specially adapted to a kind of deep open pit inclined shaft crushing system producing 500-4000 ton per year, can be widely used in mining transport and crushing technology field.
Background technology
The deep open pit mine truck car load Lifting Convey technique that 40 ~ fifties of last century proposes, by hoist engine by the mine truck car load of filling ore deposit rock from the bottom of dark recessed excavating plant along track drawing to stope top, then the crushing plant be transported to away from stope by mine truck carries out fragmentation.It is heavy by 45% that deadweight due to car load is about material, adds additional the holding capacity of tractive force that hoist engine promotes and roadbed; The slope track promoting car load is in addition fixing, and deepening is with mobile dumb.It is high that above factor causes deep open pit Lifting Convey technique running cost, and arrangement technology facility difficulty is large and mobile inconvenient, reduces the operating rate of deep open pit Lifting Convey technological work.
For the ease of the transport of ore, also have a kind of mode to be crushing engine is directly built in the bottom of dark recessed excavating plant, the ore of Bottom of Stope is given crushing engine by mine truck, and selects factory or refuse dump by being transported to sealing-tape machine after crusher in crushing.But, along with the deepening of the dark recessed excavating plant degree of depth, need not offset to establish Crushing Station, reinstall crushing engine in new bottom, so not only cause the waste of equipment, but also add the cost of building operations.Seek a kind ofly to transport the high and economic method of ore deposit rock efficiency outward from deep open pit for this reason, to ensure deep open pit production capacity, reduce freight.
Summary of the invention
In order to overcome the problem existing for prior art, the object of the invention is to provide a kind of deep open pit inclined shaft crushing system, by the mode that mine car promotes and slope track extends, both solve car load and promote the extra increase hoist engine lifting traction force and roadbed holding capacity that cause, and slope track deepening moves inflexible problem, solve again the problem that equipment is wasted and building operations cost increases that not offset establishes Crushing Station to cause.Ensure deep open pit production capacity, reduce freight, reduce investment outlay, safe and reliable.
The object of the present invention is achieved like this, a kind of deep open pit inclined shaft crushing system comprises the track be laid on dark recessed excavating plant top and slope, be arranged on the hoist engine at dark recessed excavating plant top, it is characterized in that steel-structure box ellbeam is installed in combination on the slope of dark recessed excavating plant, track laying on slope is on steel-structure box ellbeam, and track is provided with mine car; Hoist engine is connected with mine car by head sheave guiding device and wire rope group; The deep working bank of dark recessed excavating plant is provided with dumping platform, and mine car is subject to ore deposit by automobile on the working bank of dark recessed excavating plant deep on dumping platform; At the top of dark recessed excavating plant and the below being positioned at track is provided with Crushing Station blow tank and primary mill, mine car rises to dark recessed excavating plant top by hoist engine, be discharged into by ore in Crushing Station blow tank, ore selects factory or refuse dump by being transported to sealing-tape machine after primary mill fragmentation.
Described track is two groups, and often organize on track and have a mine car, two mine cars do the counterweight of hoist engine mutually.
Described mine car is unpowered mine car, and the load-carrying of mine car maximum volume and automobile matches.
A kind of deep open pit inclined shaft of the present invention crushing system, moving of Crushing Station is replaced to establish by the mode of mine car lifting and slope track deepening, replace promoting automobile by promoting light mine car, make automobile to the dumping position of mine car raw ore (rock) along with the deepening of the dark recessed excavating plant degree of depth deepening, both car body had been solved in car load Lifting Convey technique from great, running cost is high, arrangement technology facility difficulty is large and move inconvenient problem, in turn saves the building operations cost building Crushing Station bottom dark recessed excavating plant.This system have exploitation Rock stripping cost low, flexible, promote little, the track of pulling force and steel-structure box ellbeam holding capacity is little, environmental protection, energy-efficient, safe and reliable, open-air pit promote the features such as range of application is large, production capacity or from expanded reach, all reach the world initiate and fill up international blank, there is larger economic benefit and social benefit.
