Description
Technical field
It is specifically a kind of from the shrink for slipping formula ore chute ore removal the present invention relates to mine underground production technique field
Breast stoping.
Background technology
Ore body and the medium level consolidated above of roof rock or slight slope and thin ore body, are generally returned using breast stoping
Adopt.When the slanting angle of ore body reaches 30 ° -45 °, the ore of each avalanche wants local shrink as workbench, treats whole block stoping
After end, then the ore persisted all transported, here it is shrinkage and breast method.Because the slanting angle of ore body is pacified naturally less than ore
Angle is ceased, generally requires and is gone out respectively along stope trend and incline direction relay using two scrapers during shrinkage and breast method back production
Ore deposit.The ore removal way of this relay haulage, not only ore removal complex procedures, energy resource consumption height, and labor strength is big, operation
Security is poor, and production capacity of mining field is low.
The content of the invention
The invention provides a kind of from the shrinkage and breast method for slipping formula ore chute ore removal, by stope studding rock mass
Set up on one side and slip formula ore chute certainly using what steel sole plate added unilateral baffle arrangement, during ore removal, it is only necessary to use the ore of avalanche
Electric rake haulage to ore chute, ore is slipped to ore pass certainly along chute.It is this to be adopted comprehensively from the shrink for slipping formula ore chute ore removal
Ore deposit method, significantly reduces mining energy resource consumption, alleviates labor strength, improves production capacity of mining field and back production is made
Industry security.
Technical solution of the present invention is described with reference to the drawings as follows：
A kind of shrinkage and breast method for slipping formula ore chute ore removal certainly, the mining methods comprise the following steps：
Step 1: dividing nugget along orebody trend, the tilt length 60-70m of each nugget, nugget width 40-50m are applied
Industrial and mineral block adopts accurate and Undercut engineering, forms stope；
Step 2: before every slicing, being set up on one side in stope studding rock mass add unilateral baffle plate using steel sole plate first
Structure slips formula ore chute certainly；
Step 3: reverse caster successively back production, 1/3 being transported every time and falls ore deposit amount, remaining ore is persisted in stope as above adopting
Platform；
Step 4: stope all falls after ore deposit finishes, the ore for persisting stope is transported, stope mining is completed.
The specific method of described step one is：
11) haulage drift 10 outside arteries and veins, Chuan Mai tunnels 1, pedestrian's vent (-escape) raise 4, connecting taxiway are tunneled respectively according to sequencing
9th, ore pass 2, Undercut tunnel 3；
12) it is that working space progress stope undercuts with Undercut tunnel 3.
The specific method of described step two is：
It is starting point with ore pass 2, is set up on one side in stope studding rock mass 6 from slipping formula ore chute 5, using rock drill along upper
It is about the lower to drilling of 0.5m to adopt direction and make a call to a depth every 0.8m-1.2m in stope sill, and intubating length is 1m round steel
12, by steel sole plate 11 and baffle plate 13 with the firm welding of round steel 12.
The specific method of described step three is：
Driling explosion, ventilation and ore removal, ore removal using scraper 8 along orebody trend by ore handling to slipping formula ore chute certainly
5, ore transports 1/3 and falls ore deposit amount along chute from slipping to ore pass 2 every time, and remaining ore is persisted in stope as above adopting platform.
The specific method of described step four is：
41) situation is consolidated according to ore-rock, top is protected by the way of anchor pole or reserved irregular pillar；
42) repeat to set up from formula ore chute 5 and other back production steps is slipped, until stope all falls ore deposit and finished；
43) transport stope and persist ore 7, complete stope mining.
Beneficial effects of the present invention are：
The present invention is successively set up from formula ore chute is slipped upwards with stoping operation circulation, and the presence of formula ore chute is slipped certainly,
The complicated Mining procedure of relay ore removal is avoided, ore drawing in stope efficiency greatly improved, mining energy resource consumption is reduced, subtracts
Light labor strength, improves production capacity of mining field and stoping operation security.
