Abstract
The present invention relates to an underground mining method for various types of useful ore, which belongs to the mining field. The present invention is characterized in that an ore drawing system composed of four ore drawing ports is arranged in an ore column between two ore rooms to complete ore drawing tasks in two mining sites and the self ore column. The present invention has the advantages of great simplification of mining method and structure, work load reduction of mining and cutting, mining productivity increase and production cost decrease.
Description
The invention belongs to the underground mining of the underground mining methods of the various valuable minerals of field of mining, particularly thick ore body.
The sublevel drilling stage ore caving mineral building method that people recommend is in the stope bottom 16 funnels (drawhole) to be set to adopt the scraper ore removal, and its class production capacity is 150 tons; Use the scraper ore removal, its class production capacity is 65 tons; Require the raw ore lumpiness must not surpass 400mm; Bulk output capacity height under the sublevel drilling condition; Second-time breakage is frequent, and drawhole is destroyed greatly, has a strong impact on production.Be difficult to satisfy that to select factory's day output be 3000 tons requirement.
Purpose of the present invention is exactly the deficiency at sublevel drilling stage ore caving mineral building method, to solve the influence of lump ore to ore drawing, reduces to adopt and cuts engineering quantity, improves mining production capacity, satisfies the needs that select 3000 tons of day outputs of factory.
Technical scheme of the present invention is: under the nugget size condition that the die is cast of sublevel drilling stage ore caving mineral building method, change former stope 16 funnels in bottom (drawhole) into 4 funnels in a symmetrical arrangement 9, be arranged in the studding 2; Horn mouth at funnel 9 is installed chamber 3 to stope position excavation bobbing machine; This chamber 3 is positioned at lateral column 15; Arrange a haulage drift 14 in lateral column 15, from the one side, upwards excavate the short drop shaft 8 of finger-like, the chamber 3 that is provided with bobbing machine 4 and bar grizzl(e)y 5 with top communicates; To finish working continuously of bobbing machine ore drawing → Vibration rod screen → bobbing machine dress ore deposit.
Feature of the present invention also is: the base plate of mineral building vertically becomes waveform, and two troughs are positioned at bobbing machine emits on the center line of direction, and tilts 15 °.
Compared with the prior art the present invention, has fully shown following advantage in the practical application of underground mining:
1. method is easy, and the stope engineering quantity of polycrystalline substance has only 1/4th of former scheme;
2. the polycrystalline substance steadiness is good, work safety;
3. polycrystalline substance has the second-time breakage function, has solved the problem that does not go out the gallery greater than the bulk of 400mm;
4. it is identical with the scraper scheme to produce investment, but cost of production reduces significantly;
5. throughput potential is big, and 4 bobbing machines can turn round simultaneously, opens the production requirement that 2 classes just can satisfy 3000 ton per days.
Above-mentionedly can finish the ore drawing task of two stopes and ore pillar itself, simplify the mining methods structure widely, reduce to adopt and cut engineering quantity, reduce production costs, the raising production capacity of digging up mine once 4 drawhole systems of cover.
Be further described below in conjunction with accompanying drawing:
Fig. 1: design embodiment schematic diagram of the present invention;
The A-A sectional view of Fig. 2: Fig. 1.
Numbering implication in the accompanying drawing: waveform foundation stope (mineral building) 1, studding 2, bobbing machine is installed chamber 3, stope bobbing machine 4, Vibration rod screen 5, the qualified lumpiness 6 in screening back, greater than the bulk 7 of 400mm, finger-like drop shaft 8, bottom drawhole 9, ore 10 under just having collapsed, ore caving fanhole(s) 11, cutting groove 12, bottom bobbing machine 13, haulage drift 14, lateral column 15, connection roadway 16.
Accompanying drawing has represented design scheme of the present invention: under the nugget size condition that the die is cast of sublevel drilling stage ore caving mineral building method, change 16 funnels in former stope bottom into 4 funnels in a symmetrical arrangement 9, be arranged in the studding 2; Horn mouth at funnel is installed chamber 3 to stope position excavation bobbing machine; This chamber 3 is positioned at lateral column 15; Arrange a haulage drift 14 in lateral column 15, from the one side, upwards excavate the short drop shaft 8 of finger-like, the chamber 3 that is provided with bobbing machine 4 and bar grizzl(e)y 5 with top communicates; To finish working continuously of bobbing machine ore drawing → Vibration rod screen → bobbing machine dress ore deposit.
Accompanying drawing is a specific embodiment, has described working condition of the present invention.
The structural parameters of stope are:
The length of mineral building * wide * height: 64 * 20 * 68 (m)
Studding is thick: 15m
Lateral column is thick: 15m
Vibrating drawing machine 4 and Vibration rod screen 5 are placed in this chamber 3; In the lateral column 15 of the 64m length of this chamber 3 between the long mineral building of two 64m; Arrange a haulage drift 14 in lateral column 15, from the one side, upwards excavate the short drop shaft 8 of finger-like every 15m, the chamber 3 that is provided with bobbing machine 4 and bar grizzl(e)y 5 with top communicates; The base plate of mineral building vertically becomes waveform, two troughs are positioned at bobbing machine and emit on the center line of direction, and tilt 15 °, by fanhole(s) 11, to chamber 3, bobbing machine 4 and Vibration rod screen 5 are forced ore to emit and sieve again from mineral building 1 with the ore throwing, by the short drop shaft 8 of finger-like, in mine car, adorn the ore deposit by bottom bobbing machine 13, form the streamline of working continuously.
