Description
Technical field:
The invention belongs to the metal mining method, incorporate the row of pillar recovery and dead zone processing into, be under the jurisdiction of shrinkage method pillar recovery technical field in this group of pillar recovery method of opening wide mineral building, the artificial intervening pillar construction method of two kinds of material gluings of a kind of employing particularly is provided.
Background technology
Shallow eye shrinkage stoping is to come out and through producing after mine locating visits clear orebody mining technical condition, divide several nuggets according to ore-rock stability on orebody trend length in two stages (or stage casing) developing up and down.General 40～the 50m of nugget length, miding level height 35～60m, ore body horizontal breadth 3～15m, the slanting angle of ore body is greater than 55 °.And divide earlier mineral building and ore pillar before the block stoping, and ore pillar comprise foundation (thick 3～5m), fore-set (and high 3～5m) with studding (wide by 5～8m), ore pillar ore deposit amount generally accounts for about 30% of nugget ore deposit amount.Its back production step is earlier to use the shallow hole shrinkage stoping method rooming, treat mineral building adopted and go out clean ore after reclaim ore pillar again.The general studding that reclaims earlier of the method that reclaims ore pillar reclaims top-bottom pillar again.To the fan shaped medium length hole rock drilling, divide the disposable charge explosion of plurality of sections to reclaim on using vertically in the stope connecting taxiway of studding recovery method in studding; And top-bottom pillar, be in tunnel, last stage casing vertical down to last to the Drilling fan shaped medium length hole, the avalanche of detonating of also disposable whole powder charge branch plurality of sections is reclaimed.These background informations can be found on university textbook, but we and above-mentioned recovery method difference are, ore pillar is divided good back and also used the shallow hole shrinkage stoping method back production earlier before the goaf is formed, adopt the dead zone, back and form the globality artificial intervening pillar with two kinds of material cementing fills again, again its adjacent stope of back production.
Gold 1993＜8〉application of thick gold ore-body in inclination " at interval artificial intervening pillar shrink breast stoping " of 26～28 publications introduce Su Jia shop, Xixia City, Shandong Province gold mine, ore body is made up of auriferous pyrite quartz vein, yellow iron sericitolite etc., 35～45 ° at inclination angle, average vertical thickness 4m, use is the concrete applicable cases and the pluses and minuses of the back production of artificial intervening pillar shrink breast stoping at interval.Divide nugget along orebody trend with adopting the accurate slot raise of holding concurrently, disposable pick 3m is wide for courtyard, the centre is built the wide 2m of studding at interval by laying bricks or stones with barren rock, cutting well when a side stays the wide space of 1m as pedestrian, ventilation, the back production of double as mineral building, both sides artificial intervening pillar are at interval constructed afterwards the middle mineral building of back production again.Because of thick in the ore body and inclination, mineral building back production shrink breast stoping, i.e. mineral building layering raise mining, local ore removal stays the part ore and adopt workbench on continuing, and mineral building has been adopted afterwards with a large amount of ore removals of scraper.This law great advantage is that shrink stone does not push up the end and studding, ore recovery rate height; To construct workload big and shortcoming is artificial partition wall.Its relevant part with this law: the one, the back production of nugget studding elder generation; The 2nd, studding is with manually constructing; The 3rd, rooming again after studding is constructed.And difference is: the one, and a column length difference, this law 4～7m; The 2nd, do not stay any space after the studding back production, and be to use integral body of all glued one-tenth of two kinds of materials.
Summary of the invention
The invention provides the artificial intervening pillar construction method of two kinds of material gluings of a kind of employing, solved (the problem of 3.0～15.0m) continuous (trend and vertical length are all greater than 100m) and the back production of grade higher (more than 7～10g/t) rock gold ore-body thick in the high-dipping (55～90 °), replace the ore ore pillar with artificial ore pillar, goaf after middle part back production of continuous ore body and ore removal finish is spaced from each other, and adjacent stope can use production capacity big, the shallow hole shrinkage stoping method exploitation that efficiency is high and cost of production is low, stop its goaf to enlarge to produce and cave in, cause ore removal that bigger loss and dilution take place; In addition, for making artificial intervening pillar back production and formation speed faster, so, just require the back production length of studding to dwindle, extraction ore deposit and loading time are short, and require the strength of filling mass of globality to reach more than 5～7Mpa.
Concrete grammar of the present invention is:
(1) visits orebody occurrence such as clear ore body horizontal breadth, inclination angle, grade, double dirt loader ore removal lane of making the shallow hole shrinkage stoping method stope, this tunnel by the vertical orebody trend driving of the outer transportation of lower wall arteries and veins Chuan Mai tunnel with the airway;
(2) delimit in stage casing up and down and dig a mine locating double as in the nugget scope from bottom to top and adopt accurate courtyard;
(3) stage casing, ore body bottom is by 4～7m length, and the overall with cutting also all goes out clean ore;
(4) at incised layer construction reinforced bar concrete artificial sill pillar;
(5) adopt the shallow hole shrinkage stoping method back production to last stage casing level from bottom to top by nugget total length and the complete thick 3～7m of ore body;
(6) a large amount of ore removals and the whole emptying of ore after the mineral building back production;
(7) tunnel that all and this stope is mutually saturating adds cement mortar with piece stone and builds a wall to block and obturage in the stage casing, bottom;
