Abstract
The invention relates to a technology for lifting underground hard rock minerals by a shaft, which is characterized in that compressed air at the bottom of an ore conveying pipe is used as power, and three-phase fluid of liquid, solid and gas continuously ascends along the ore conveying pipe to lift the minerals in the ore conveying pipe. The method of hoisting the container by the hoister is replaced, so that the workload of shaft tunneling is saved, the facility is simplified, the investment is reduced, and the energy is saved.
Description
A kind of technology of lifting hard rock mineral from underground by vertical shaft is applicable to the lifting subsurface mineral.
The large medium-size mine of underground mining mineral adopts shaft development more, with skip bucket or cage with the mineral of underground mining along shaft hoisting to the face of land, belong to a kind of operating type discontinuously, because the frequent starting of elevator, quicken, braking, operating condition is abominable, so, big safety factor is all selected in the design of Hoisting System for use, increased the section of vertical shaft, in mining design, time that vertical shaft is dug well and the construction of Hoisting System takies and investment proportion maximum are owing to above-mentionedly belong to a kind of interruption operating type, the operating efficiency of Hoisting System only is 0.4-0.6, and energy consumption and operation cost are difficult to reduce.
The objective of the invention is problem at above-mentioned existence. propose a kind of simplicity of design, small investment, save the technology of the lifting hard rock mineral from underground by vertical shaft of the energy.
A kind of technology of lifting hard rock mineral from underground by vertical shaft is characterized in that:
A. the compressed air with defeated pipe bottom is the power of mineral Hoisting System in vertical shaft;
B. in defeated pipe, with liquid, solid, the continuous ascending motion lifting of the defeated pipe in gas three-phase flow body edge mineral.
Owing to adopt above-mentioned technology, the present invention is interrupted method for improving with the vertical shaft container and compares, water-supply-pipe and defeated pipe can be arranged on the pipeline enclosure of auxiliary shaft, thereby can replace a pair of vertical shaft by a vertical shaft, simplified the lifting facility, reduced construction investment, promoted operation with liquid, container solid, that the serialization of gas three-phase flow body promotes operation replacement interruption, save the energy, also improved the automatization level that promotes operation simultaneously.
Accompanying drawing is embodiment of the present invention schematic diagrames.
Embodiment in conjunction with the accompanying drawings further describes as follows to the present invention:
In practical application of the present invention, after the dress mineral water of water-supply-pipe 1 arrival down-hole is flat, tell a water route with the pulping treasured 4 that leads to withstand voltage ore storage bin 3 and side thereof communicating pipe 2, program when the starting three-phase fluid promotes the mineral operation is: a. turn-offs the air-supply valve door 6 on the compressed air hose of failing under the pipe 5 earlier, open the valve 7 on the water-supply-pipe, turn-off the valve 8 on communicating pipe; B. open the water supply valve 10 in pond, the face of land 9, supply water to water-supply-pipe and defeated pipe, make water-supply-pipe and defeated pipe be full of water, water is communicated with at the place, U-shaped bottom that water-supply-pipe is connected with defeated pipe; C. open the air-supply valve door on the compressed air hose 11 of defeated pipe lower end then, feed compressed air to defeated pipe, formation proportion is less than 1 the gas that moves upward, liquid two-phase fluid in defeated pipe; D. the gas in defeated pipe, when liquid two-phase fluid upward speed reaches the movement velocity of design, open the valve on communicating pipe, in clarified water pump 12 that startup is supplied water to the pulping chamber and the withstand voltage ore storage bin to the pulping chamber rock feeder 13 for the ore deposit, make ore pulp for the pulping chamber, this ore pulp is brought defeated pipe into by the negative pressure that forms in the defeated pipe in exit, pulping chamber, form liquid, solid, gas three-phase flow body jointly with gas, liquid two-phase fluid in the defeated pipe; E. adjust the compressed-air actuated pressure enter in the defeated pipe, flow, the proportion that makes the new liquid that forms in the defeated pipe, solid, gas three-phase flow body be less than 1, and continuously along ascending motion in the defeated pipe, thereby realize that mineral promote along vertical shaft 14; That f. adjusts the pulping chamber goes into the water yield and mine-supplying quantity, promptly adjusts the pulping concentration of pulping chamber, will fail the liquid in the pipe gradually, mine-containing amount solid, the gas three-phase flow body is brought up to design load; G. in service liquid, solid, the flow velocity of gas three-phase flow body, flow, concentration, pressure parameter are monitored promoting, and feed back to control system, make lifter motion be in optimum duty.
Ore 16 after broken chamber 15 fragmentations above the withstand voltage ore storage bin is sent to withstand voltage ore storage bin by belt conveyer 17.
Water-supply-pipe diameter of the present invention is greater than defeated pipe diameter or in the flat fluctuation of building the favourable minimizing Hoisting System of voltage stabilizing sump pressure parameter of dress mineral water.
