Abstract

The invention belongs to the technical field of underground mining processes, in particular to a flat-bottomed trench shallow hole shrinkage method. The mining process comprises: ore mining from a two-section bord, ore loading by a horizontal trackless forklift and ore removal by transportation equipment, namely pull-bottomed plane and secondary pulverization plane are combined on the same plane till on the same level with transportation plane to form a flat-bottomed trench; the method adopts a bottom trench ore removal mode; the bottom of the bord is a plane; ore on the pull-bottomed plane is a triangular ore pillar; according to the occurrence condition of an orebody and the prior engineering condition, the orientation of the orebody is determined in a horizontal subsection; a horizontal transportation tunnel is dug in an orebody footwall; a cross vein trackless ore removal tunnel is dug towards the orebody in every 25 m to form a cross vein ore removal and vein-following loading transportation mode; the ore removal tunnel selects the vein-following arrangement or the cross vein arrangement of the ore removal tunnel according to the width of the orebody; and the number of the ore removal trench is 1 to 2. The flat-bottomed trench shallow hole shrinkage method improves the operating rate and reduces loss and dilution.

Description

Flat-bottomed trench shallow hole shrinkage method
Technical field
The invention belongs to underground mining technology field, particularly a kind of flat-bottomed trench shallow hole shrinkage method.
Background technology
The shallow hole shrinkage method ore removal is that the mineral building extracted ore is worn the ore deposit to slusher drift by bucket well bucket, by rake ore deposit winch with the ore dumping to the ore removal drop shaft, rock intercalation in the ore body can't be rejected in the ore removal process and all is blended in the drop shaft, can only be checked that judgement is whether qualified and decides choice going out mine car by controlling unit according to the inner ore outgoing inspection standard of formulating in each mine.Because the interlayer rock is sneaked into and is caused the low and part mine car ore of ore export potential drop to mix the rock rate to exceed standard and give up, cause the loss and the dilution of ore, particularly to reclaim the later stage stoping limit ore ore removal recovery difficult of nugget studding, top board bigger for the explosion chamber, makes part output blending mix rock and exceed standard and can't reclaim and lose.
Summary of the invention
The purpose of this invention is to provide a kind of flat-bottomed trench shallow hole shrinkage method.Replace winch rake ore deposit, rake ore deposit with trackless forklift dress ore deposit.
The objective of the invention is to realize by following technical proposals.
Flat-bottomed trench shallow hole shrinkage method of the present invention, it is characterized in that mining process is: two sections mineral building extracted ore → horizontal trackless forklift dress ore deposit → haulage device ore removals, promptly undercuting level, the second-time breakage level is incorporated in same level, until with haulage level on same level, form flat moat ditch, adopt bottom moat ditch ore removal mode, the mineral building bottom is the plane, ore is the triangle ore pillar in the level of undercuting, on horizontal fragmentation, depositing situation and existing project situation according to ore bodies determines along orebody trend, drive horizontal haulage drift at the ore body lower wall, drive to ore body every 25m and to wear arteries and veins trackless ore removal tunnel, form and wear the arteries and veins ore removal, along the pulse entrucking means of transportation, this ore removal moat ditch is the 1-2 bar.
Described ore removal haulage device is a trackless forklift equipment, forms scraper moat ditch ore removal mode.
When orebody thickness during less than 10m, described ore removal moat ditch is 1 ore removal moat ditch.
When orebody thickness during greater than 10m, described ore removal moat ditch is 2 ore removal moat ditches.
The ore removal tunnel of described moat ditch ore removal is selected to arrange the ore removal tunnel along the pulse according to the width of ore body or is worn arteries and veins and arrange the ore removal tunnel.
Flat-bottomed trench shallow hole shrinkage method of the present invention, studding on the section, fore-set, mineral building structural parameters are constant.Production efficiency improves 30%, and stage casing production capacity improves 12%.Realize dividing load and carry, having strengthened neutralizes joins the flexibility in ore deposit, has guaranteed the stability of output ore quality.Quality index improves, and mixes the rock rate and reduces by 4.74%, and the output grade improves 1.58%.
Description of drawings
Fig. 1 is a flat-bottomed trench shallow hole shrinkage method schematic diagram of the present invention.
The specific embodiment
Below in conjunction with description of drawings the specific embodiment of the present invention.
As shown in Figure 1, flat-bottomed trench shallow hole shrinkage method of the present invention, it is characterized in that mining process is: two sections mineral building extracted ore → horizontal trackless forklift dress ore deposit → haulage device ore removals, promptly undercuting level, the second-time breakage level is incorporated in same level, until with haulage level on same level, form flat moat ditch, adopt bottom moat ditch ore removal mode, the mineral building bottom is the plane, ore is the triangle ore pillar in the level of undercuting, on horizontal fragmentation, deposit situation and existing project situation according to ore bodies and determine to drive horizontal haulage drift 1 at the ore body lower wall, drive to ore body every 25m and wear arteries and veins trackless ore removal tunnel 5 along orebody trend, the arteries and veins ore removal is worn in formation, along the pulse entrucking means of transportation, this ore removal moat ditch is the 1-2 bar.
Described ore removal haulage device is a trackless forklift equipment, forms scraper moat ditch ore removal mode.
When orebody thickness during less than 10m, described ore removal moat ditch is 1 ore removal moat ditch.
When orebody thickness during greater than 10m, described ore removal moat ditch is 2 ore removal moat ditches.
The ore removal tunnel 5 of described moat ditch ore removal is selected to arrange the ore removal tunnel along the pulse according to the width of ore body or is worn arteries and veins and arrange the ore removal tunnel.Label 2 among the figure is a tailgate, and 3 is courtyard, and 4 is the courtyard connection roadway.
Flat-bottomed trench shallow hole shrinkage method of the present invention, studding on the section, fore-set, mineral building structural parameters are constant.Production efficiency improves 30%, and stage casing production capacity improves 12%.Realize dividing load and carry, having strengthened neutralizes joins the flexibility in ore deposit, has guaranteed the stability of output ore quality.Quality index improves, and mixes the rock rate and reduces by 4.74%, and the output grade improves 1.58%.
