Abstract
The horizontal room-and-pillar stoping of gently inclined orebody, it with the difference of main feature and the basic technical scheme thereof of conventional pillars of a house method is: conventional pillars of a house method is generally along orebody strike back production, electric scraper discharging, the well that slips is transported, stage casing entrucking, stope cannot be suitable for high efficiency equipment voluntarily, causes technique loaded down with trivial details, barren rock digging rate height, throughput is low; This scheme carries out developing and in-vein preparatory work in arteries and veins, does not arrange transhipment and slips well, and the straight-through stope of runway runs through upper and lower stage casing, mineral building lateral arrangement, all uses equipment shipment voluntarily, and bunching or automobile can directly enter stope by ore deposit, production efficiency can increase substantially, and reduces barren rock digging.
Description
Technical field
The invention belongs to mine technology field
Background technology
Current state of the art: left and right, 20 �� of angles small pitch is thin��the exploitation inefficiency always of middle thickness orebody; Owing to avalanche ore easily tumbles along slope, spreads, equipment cannot carry out ore deposit operation voluntarily, and mine is continue to use the mining type along tendency back production, scraper carrying, Pass drawing, the outer transportation roadway entrucking of arteries and veins always; Not only production efficiency is low for this kind of mode, and causes a large amount of barren rock digging, is unfavorable for saving, High-efficient Production; The object of the present invention has be change stope structure form at three: one, formula mining equipment voluntarily can be marched into the arena operation, it is to increase mining intensity; Two is change developing and adopt accurate layout, adopts developing, in-vein preparatory work mode in arteries and veins, to reduce and to eliminate barren rock digging amount, it is achieved save and produce; Three be cancel slip well transhipment, by level haulage equipment introduce stope directly load, simplify ore transportation technology link, improve production efficiency.
Summary of the invention
The major programme of the present invention is: (one) whole Transporting system: level haulage lane is opened up along orebody trend arteries and veins, arranges that a pseudo-inclination runway is through between upper and lower level haulage lane, and top, road, slope arranges slow dynamic winch, service hoisting; When adopting mine car to transport, laying a railway track, establish and uncouple and track switch in road, slope, bunching rises to stope by bottom transportation roadway, transfers to bottom transportation roadway outward transport after entrucking again; When adopting automobile to transport, slope Road Base suitably caves in, and to reduce entrucking height, automobile is transferred by top transportation roadway and entered stope, continues to transfer to bottom transportation roadway outward transport after entrucking; (2) accurate layout is adopted: arrange back mining blocks in runway both sides, ore deposit block axis and runway oblique, Gu claim horizontal pillars of a house method; Each layer of ore deposit block is a mining segmentation, and ore deposit block length is determined by the rational transportation distance of carrier loader, and mineral building width and a post specification are determined by ore and rock stability; Article one, multiple segmentation ore deposits block of runway both sides forms one and independently transports exploiting field; (3) adopt accurate engineering: mineral building newel post and runway protection ore pillar between security measures chamber is set, this chamber be namely ore deposit block mainly adopt accurate engineering; Chamber side of going down the hill arranges that mineral building transportation roadway is held concurrently crossheading, UNICOM's mineral building and runway, forms ore drawing in stope passage; Ladder walkway, device channels and measure platform are arranged in chamber side of going up a hill; Wherein ladder walkway and the through upper and lower segmentation of device channels; Measure platform is the triangular shaped recess step that excavation floor rocks is formed, for carrier loader tune, keep away big gun, stope distribution and tool storage; (4) cutting method: by mineral building newel post, versant driving cutting lane under mineral building; Meanwhile, by quick-fried slag backfill leveling mineral building transportation roadway, scraper equipment availability condition is formed; Cutting lane height depends on orebody thickness, and cutting lanewidth degree is not less than 4.0m, pulls out three profiles of post between mineral building during cutting; (5) stoping method: the back production order between segmentation is from top to bottom; Utilizing cutting lane to be compensation space, drawing back, adopts shallow hole or medium-length hole according to orebody shape; (6) ore drawing in stope: mineral building transportation roadway for going out ore deposit passage, scraper equipment protrusive enter mineral building dress ore deposit, retreat to measure platform tune, to runway unloading, then back to measure platform tune, enter mineral building, so repeatedly; Slope eluvial ore in mineral building and upper segmentation footing residual ore body, utilize a kind of have before after rake the track type rake slag machine of unloading functions reclaim, the type rake slag machine has more than 25 �� gradeabilities, it is possible to reclaim the residual ore deposit, corner of mineral building; (7) equipment tranfer system: the device channels of runway both sides, it is possible to shift mining equipment between upper and lower segmentation, but due to the gradient relatively big, by the slow dynamic winch service hoisting on runway top and need to transfer; The equipment transfer crossing over runway generally will via level haulage lane; (8) stage casing back production order: between stage casing, recommends to exploit from bottom to top, can by lower for the backfill of upper stage casing digging barren rock worked-out section, stage casing; (9) pillar recover: block stoping avalanche can reclaim mineral building newel post after terminating; The protection ore pillar of runway is after hole is closed in this exploiting field, and avalanche is reclaimed piecemeal from top to bottom; The protection ore pillar in level haulage lane, after hole is closed in this stage casing, reclaims with Non-sill-pillared sublevel caving; (10) necessary security measures: go down the hill the ore pillar interstitial site of side adopting sky mineral building, Rolling Stone protection fence is set, to ensure lower segmentation back production safety;All the other minings are ordinary method substantially, repeat no more.
