Abstract

A mining method constructed that mine with the deep holes in underlie rock drill tunnel, the stope board is constructed a little bigger than the ore angle of response, the segmented tunnel is near the ore body, lay out mine road separately, the carry scraper transport out mines, the hanging side is filled with ventilation canopy guard and construction cable in tunnel to protect the upper plate, the method applies to difficult mining, ore bodies exists in fracture zone, fractures develop, hanging side broken, easy to collapse, the upper plate of ore body allows a small exposed area, gently inclined, with big changes in the thickness , shape and boundaries of the ore body, the surface is not allowed to collapse.

Description

A kind of mining methods
Affiliated technical field:
The present invention relates to a kind of mining methods, particularly a kind of segmentation squeezing mine collapse arteries and veins outer room is separated out the ore deposit and follows the continuous mining codes of filling
Background technology:
At present, big for ore body thickness, ore bodies is stored in the fault zone, cranny development, last dish is broken, very easily caves in, and the top board of ore body allows exposed area little, more than the gentle dip, varied in thickness is big, and ore body border and change of shape are big, and the face of land does not allow the ore body that subsides, the conventional mining methods in past are difficult to back production, and very dangerous.
The invention task:
It is big to the purpose of this invention is to provide a kind of solution recovery ore body thickness, and ore bodies is stored in the fault zone, cranny development, last dish is broken, very easily caves in, and the top board of ore body allows exposed area little, varied in thickness is big, and ore body border and change of shape are big, and the face of land does not allow the ore body mining methods of subsiding.
The object of the present invention is achieved like this: a kind of mining methods is characterized in that:
1. in ore body lower wall construction segmentation lane: the stage casing is divided into 2~3 little stage casings, and each little stage casing is divided into 2~3 segmentations, and segmentation is high by 8 -10m;
2. the mineral building across pitch carries out back production: the boundary at the ore body lower wall is arranged drilling drift along the pulse, and lower wall is provided with an ore removal connecting taxiway every 3~4 meters, arranges ventilation, filling, Hu Ding tunnel at the segmentation top by dish position on the ore body;
3. segmentation lane supporting: before the exploitation, in filling ventilation Hu Ding tunnel, carry out the supporting of New-type long-acting anchor pole or anchor cable according to the firm situation of balkstone;
4. exploitation: with 70 ° of fan shaped medium length holes of FC ore deposit that falls, from the end in little stage casing to the other end or two ends to pushed, per 2~3 subsections spatially form the successive steps formula and advance, rock drilling, explosion is parallel carries out continuously, while or segmentation ore removal, with the classified tailings primary filling of no gelling agent, the stope base plate gradient can be constructed into the inclination angle and is slightly larger than the ore angle of repose, is convenient to ore and flows automatically to lower wall then.
5. ore removal: adopt electric LHD, shovel into the lower wall ore pass, transport ground through connecting taxiway.
The present invention compared with prior art has the following advantages:
Adopt the method, have following effect:
1. production capacity of mining field is big
The rock drilling of each segmentation is parallel to be carried out, 2~3 same separate explosions of segmentation, explosion 3 row (3.6m) but about 2000 tons of big gun hole broken ores (pressing 20 meters of thickness), if once collapse 6 artillery salvo holes (7.2m), then but broken ore is about 4000 tons, can be in 2~3 segmentation tunnels ore removal simultaneously; There are 2~3 segmentations in each little stage casing, if from two side direction pushed, simultaneously work plane number can reach 4~6 on little stage casing, so avalanche ore deposit amount is very big, adds that the ore removal passage is many, the efficient height, so production capacity of mining field is big;
2. operational security height
Rock drilling is carried out in the tunnel, and ore removal carries out in connecting taxiway, job safety.In exploitation process, firm situation according to the stope top board, can ventilate to protecting in last dish filling in case of necessity and grow bolt support or long anchor cable supporting in the gallery of top, not operation in stope of scraper, because stope is adopted by force by force, cycle time for working is short, 3 segmentation primary fillings, top board open-assembly time weak point, so operational security is good.
3. the ore losses dilution is little
Owing to adopt ascending mining order from bottom to top, classified tailings with no gelling agent carries out the goaf processing do casting resin, problem is pressed on the ground that can solve the goaf effectively, thereby can consider to stay top-bottom pillar, studding and some post, got rid of the resources loss that designs a large amount of ore pillars because of the mining underground pressure management basically.Adopt the segmentation ore caving in the exploitation, segmentation or little stage casing primary filling, and the natural repose angle that makes full use of casting resin is supported oneself casting resin, and requirement is provided with a large amount of quadratic losses and the dilution that loss that the sand block rib causes and sublevel fill stoping back production cause when significantly reducing no gelling agent filling.
4. cost of winning is low
Facts have proved that these mining methods will reduce about 50% than conventional mining methods cost.

1, the stage is transported lane 2, segmentation tunnel 3, layering connecting taxiway 4, ore pass 5, filling ventilation Hu Ding tunnel 6, long anchor cable 7, obturation 8, drilling drift
The specific embodiment:
1. segmentation tunnel (2) link to each other with ramp by segmentation lane connecting taxiway, and at 8 meters of ore body lower wall, segmentation is high by 8 -10m, two or three segmentations are as a little stage casing, and 2~3 little stage casings are combined into a stage casing.
2. the mineral building across pitch carries out back production, arranges drilling drift (8) along the pulse at the boundary of ore body lower wall, and its cross dimensions is 4m * 3m; Lower wall is provided with an ore removal connecting taxiway every 3~4 meters
(3), cross dimensions is 3.2m * 3m, arranges ventilation, filling, Hu Ding tunnel (5) at the segmentation top by dish position on the ore body, and the effect of visiting web boundary line on the clear ore body can also be played in this tunnel, and its cross dimensions is 2.5m * 2.5m.
3. with 70 ° of fan shaped medium length holes of FC ore deposit that falls, lead quick-fried millisecond detonator with row with the non-electricity of section with elementary errors and detonate 2# common rocks explosive blasting.The steadiness situation of looking rock in the exploitation is determined big gun hole row's number of each explosion, and the stope base plate gradient can be constructed into the inclination angle and is slightly larger than the ore angle of repose, is convenient to ore and flows automatically to lower wall, and scraper can not enter the stope operation.
When 4. exploiting from the end in little stage casing to the other end or two ends to pushed.Per 2~3 subsections spatially form the successive steps formula and advance, and rock drilling, explosion is parallel carries out continuously, simultaneously or the segmentation ore removal, and then with classified tailings (7) primary filling of no gelling agent.
5. before exploitation, can in filling ventilation Hu Ding tunnel (5), carry out the supporting of New-type long-acting anchor pole or anchor cable, guarantee the work plane job safety according to the firm situation of balkstone.Can adopt the YGZ-90 rig to carry out perforating in the production.
6. ore removal adopts electric LHD, goes into lower wall ore pass (4) through connecting taxiway (3) shovel.
7. casting resin (7) enters mined area by fill pass, filling gallery through the over packing dehydrator, and each packed height is height of lift 8m, can divide 2~3 fillings in the little stage casing.
