Specific embodiment
The embodiment of the present invention will be described in further detail below.What is be not described in detail in the embodiment of the present invention is interior
Appearance belongs to the prior art well known to professional and technical personnel in the field.
The layer and section of breaking ore body interlayer of the invention combines recovery method, and preferable specific embodiment is：
The layer and section combination recovery method of breaking ore body interlayer includes step：
A, panel, panel barrier are successively divided along breaking ore body interlayer trend, capwise is successively drawn in each panel
Point a step mineral building stope, two step ore pillar stopes, the step mineral building stope include breaking ore body interlayer back production, and described two
Step ore pillar stope includes that breaking ore body interlayer two sides consolidate ore body back production；
B, the step mineral building stope horizontal direction is made of two parallel routes, and the route quantity of vertical direction is by dividing
Duan Gaodu is determined, has been adopted and has been filled, and is formed obturation and is replaced a column；
C, the step mineral building stope adopt charge finish after, switch to the two steps ore pillar stope mining.
The one step mineral building stope uses the back production of route consolidated fill, and the two steps ore pillar stope two sides are a step
Cemented fill, the two steps ore pillar stope are returned using the lower of long anchor cable pre-reinforcement to parallel deep hole sublevel open stoping afterwards filling
It adopts.
The extent length of the breaking ore body interlayer is the integral multiple of interlayer two sides ore body Width of stope, the broken mine
The panel barrier width of interlayer body is a Width of stope of interlayer two sides ore body, and the panel barrier later period uses to admission passage filling
Mining codes are recycled.
The one step mineral building stope uses tailing cemented filling, and the two steps ore pillar stope cementing is filled using tailings is non-
It fills out.
During the two steps ore pillar stope, stope height is improved to a height of lift, and rock drilling is arranged on stope top
Chamber, Bottom of Stope construction undercuts chamber, while stope undercuts, using overall length grouting cable anchor to breaking ore body carry out entirely plus
Gu drilling chamber uses pre- stationary point column, bolt-mesh-spurting supporting, drilling chamber top plate is supported jointly with long anchor cable, using lower to deep hole
Progress kerve, side collapse, remote-controlled scraper ore removal, and barnyard is afterwards non-cementing tailing-filled.
The layer and section of breaking ore body interlayer of the invention combines recovery method, for the geology preservation of breaking ore body interlayer
Feature and Mining technology condition, using a parallel route consolidated fill back production of step mineral building stope, the two long anchors of step ore pillar stope
The lower combination mining methods to parallel deep hole sublevel open stoping afterwards filling back production of rope pre-reinforcement, a step mineral building stope is cementing to be filled
It fills out and creates safer mining conditions for two step ore pillar stopes, realize the purpose of the safe and efficient back production of breaking ore body interlayer,
The back production that can be extended to the relatively firm ore body in interlayer two sides simultaneously, solves breaking ore body interlayer and the group of the relatively firm ore body in two sides is run jointly
Adopt problem.
Specific embodiment, as shown in Figure 1 to Figure 3：
(1) panel and panel divide such as Fig. 1, a step mineral building stope and two steps in breaking ore body interlayer of the present invention
It is the exploitation of certain copper mine underground ore bodies that rapid ore pillar stope, which divides such as Fig. 3, this example, and centre is breaking ore body interlayer, joint fissure hair
It educates, local argillization, two sides are relatively firm ore body.The relatively firm ore body mining methods in two sides are that medium-length hole sublevel open stoping afterwards filling is adopted
Mine method, production efficiency are high；Breaking ore body interlayer is not suitable for using such mining methods.If breaking ore body interlayer all using compared with
For common access back-filling method, have the shortcomings that operating location is more, production capacity is low, cost of winning is high, ventilation is of poor quality.
One step mineral building stope of invention uses parallel route tailing cemented filling mining codes, and two step ore pillar stopes are pre- using long anchor cable
That reinforces is lower to parallel deep hole sublevel open stoping afterwards filling mining method, is able to satisfy breaking ore body interlayer safety economy high winning technology
It is required that；Arrangement adopts quasi- engineering in the relatively firm ore body ore pillar stope in two sides, is arranged by adopting quasi- engineering optimization, breaking ore body interlayer
It is connected very well with the relatively firm orebody mining realization in two sides.
(2) the relatively firm ore body in this example two sides uses the afterwards filling mining method back production of medium-length hole sublevel open stoping, Width of stope
For 15m, height of lift is 20m or 25m, and breaking ore body interlayer divides panel, extent length 45m, height of lift be 10m or
12.5m, panel barrier width are 15m；A step mineral building stope horizontal direction is made of 2 extracting drifts in panel, back production into
The a length of 45m in road, width 4m；Two step ore pillar length of stope are 45m, width 8m.
When (3) two step ore pillar Bottom of Stope undercut, breaking ore body is reinforced entirely using overall length grouting cable anchor, anchor cable
Between array pitch be 2.0m × 2.0m；Drilling chamber pre- stationary point column in stope top puts column specification as 2.0m × 2.0m, while chamber top plate
Using bolt-mesh-spurting supporting.It is collapsed to deep hole kerve with side using lower, interstitial hole apertureHole pattern parameters 2.6m × 2.5m, column
Shape continuous charging structure；Lateral opening apertureHole pattern parameters 2.0m × 1.6m is spaced decoupling charge structure.
(4) two step ore pillar stopes use remote-controlled scraper ore removal, barnyard afterwards non-cementing tailings filling body backfill.Through reality
The Mining technology condition for showing that such breaking ore body sandwich combination mining technology meets breaking ore body is trampled, and more steady with two sides
Gu the exploitation of ore body has fine linking, it can achieve the purpose that safety and high efficiency.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Within the technical scope of the present disclosure, any changes or substitutions that can be easily thought of by anyone skilled in the art,
It should be covered by the protection scope of the present invention.Therefore, protection scope of the present invention should be with the protection model of claims
Subject to enclosing.
