Abstract
The concentrating mining method of inclined orebody shrinkage mining, its basic scheme is: stope pillar is along orebody strike layout arranged in parallel; Recovery phase, at the pre-buried grooving of Stope roof and wire rope, the preset wire rope leading block at fore-set position, formerly forms the structural system of scraper operation; After back production terminates, utilize bottom scraper chamber and go out mine mouth, installing scraper, from bottom to top, concentrating mining; In rake ore deposit, ore removal stage, a kind of rake of self-control ore deposit frame, impels shrink to pile body and loosens, caves in, and put together to centre, realizes tunneling boring rake ore deposit.
Description
Technical field
The invention belongs to mine technology field
Background technology
Current state of the art: 40 ° of angles tilt thin ~ exploitation of middle thickness orebody is mining circle a great problem always, back production difficulty, ore removal is more difficult; At present, generally all adopt shrinkage-breasting method to exploit: recovery phase, release about with drop shaft
the ore deposit that falls, all the other
ore stay in stope as on to job platform; Concentrating mining after back production terminates is operation dangerous, the most difficult together; Because mobile equipment cannot run on the slope, ore can not go out from rolling again, generally all will adopt electric scraper discharging; And scraper is set often will enters goaf risk operation, both difficult and dangerous, therefore the ore loss ratio in concentrating mining stage is general all very greatly, and the loss late in part mine reaches more than 30%; The object of the invention is to seek the concentrating mining difficult problem that a kind of easy, practical method solves the shrinkage method later stage, realize safety, save and produce, improve resource utilization.
Summary of the invention
Major programme of the present invention is: stope pillar is along orebody strike layout arranged in parallel; Recovery phase, at the pre-buried grooving of Stope roof and wire rope, the preset wire rope leading block at fore-set position, formerly forms the structural system of scraper operation; After back production terminates, utilize bottom scraper chamber and go out mine mouth, installing scraper, from bottom to top, concentrating mining, with reference to (a) figure and (b) figure of Figure of description 1; In rake ore deposit, ore removal stage, a kind of rake of self-control ore deposit frame, impels shrink to pile body and loosens, caves in, and put together to centre, realizes tunneling boring rake ore deposit; The specific practice of pre-buried grooving and wire rope is: as a rake mine belt between stope two ore discharge post, roughly in the middle part of rake mine belt, run rope position by the wire rope estimated, Stope roof is installed two wire rope groovings, grooving is spreading piecemeal with raise mining; Article one, the wire rope that ' U ' type is turned back is inserted in grooving immediately, and namely this wire rope is lift the up tail rope of scraper, and its one end connects or for connecing niggerhead, the other end is standby connects scraper; When grooving extends to piecemeal close to fore-set, ' U ' type bail of tail rope hangs on directive wheel; After back production terminates, utilize pre-buried tail rope to connect scraper, be assembled into rake ore deposit system, rake ore deposit, ore removal can be concentrated; The pre-buried grooving of Stope roof is protection wire rope and establishing; Grooving is made up of cell body and cover plate two parts, (c) figure see Figure of description 1: cell body is miniature channel-section steel or makes grooved with iron plate, square cavities, loosely can hold wire rope handling; Overhanging seat board is welded in cell body both sides, seat board perforate, and be fixed on top board crag by cell body with expansion bolt or nailing, Open Side Down; Cover plate is also grooved, and its inner chamber corresponds to cell body outline, and the clamping friction effect by side plate is wrapped up, block and overlay on cell body, for hiding protection wire rope; Along the grooving position line, should by adding backing plate or eliminating the means such as convex stone leveling basal plane, make that cell body is installed firmly, route is straight, docking is tight; The merogenesis length of cell body is generally not less than 3.0m, makes every effort to reduce interface, guarantees that wire rope runs smooth and easy; The merogenesis length of cover plate is generally not more than 1.5m, makes it can come off section by section when ore removal is unsettled, and not overslaugh wire rope runs; Coating butter is answered, anti-rust and lubrication in grooving; Explosion falls before ore deposit, protect and cover grooving and revealed section wire rope, after explosion, and Inspection and maintenance grooving, and with the tight landfill of slag; Structure for the rake ore deposit frame of loosening ore is: with reference to Figure of description 2, and rake ore deposit frame is primarily of framework, thorn angle, rake arms, wing plate, pin, contact wire rope and bolt composition; Framework steel plate or shaped steel are welded; Sting welded corner joint at frame front end, for loosening head-on ore; Rake arms is connected on framework by pin, can rotate around pin; Wing plate is high strength elastic plate, is fixed by bolts to rake arms end; The action principle loosening rake ore deposit is: with reference to Figure of description 2, and when up wire rope tension, lower rope relax, rake arms is in closed configuration under gravity and both sides retardation, and rake ore deposit frame facilitates up; When the tension of descending wire rope, upper rope relax, under the effect of contact wire rope, rake arms opens about hexagonal angle, can stir, loosen, both sides ore of putting together; When upper and lower pull rope all appropriate tensioning time, rake ore deposit frame is unsettled, and it is stuck to prevent from being buried ore deposit; Change the wing plate of different length and specification, then can change rake ore deposit width, because wing plate has high strength elastic, even if stretch between ore pillar, also can not be stuck, therefore can tunneling boring raking ore; Concentrating mining period, take the circumstances into consideration to change scraper and rake ore deposit frame, stope shrink all can be raked off, and operating personnel need not go through dangers and enters goaf.
