Description
Technical field
The present invention relates to a kind of mining codes, particularly relate to the mechanization sublevel cut and fill method of the collaborative back production of a kind of upright opening and lateral aperture, be applicable to that ore deposit rock moderately stable is above, inclination or Slowly inclined large and thick ore body, the safety of high-dipping middle thickness orebody, high-efficiency mining.
Background technology
Updating and developing along with mining technique and plant equipment, the shortcomings such as stratified filling method production efficiency when exploitation big thick ore body is low, cost of winning is high, two rate index height expose gradually, filling method develops out sublevel fill stoping method and Mass filling method day by day, and Mass filling method is comparatively strict to the requirement of orebody occurrence, so sublevel fill stoping method is more adopted by mine.
For sublevel fill stoping method, in exploitation process, have the problem of roof safety, traditional sublevel fill stoping method adopts the mode on pre-control top conventionally, and the method complex process, cost is higher, and concussion of blasting easily damages supporting.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of assurance under the prerequisite of job safety, realizes the upright opening of safe and efficient low-cost exploitation and the mechanization sublevel cut and fill method of the collaborative back production of lateral aperture of big thick ore body.
In order to solve the problems of the technologies described above, the mechanization sublevel cut and fill method of the collaborative back production of upright opening provided by the invention and lateral aperture, ore body is divided into stage casing in short transverse, in stage casing, be further subdivided into segmentation, according to ore-rock stability, determine rational mineral building length and width, using this as a back production unit; Adopt the outer trackless of arteries and veins to adopt standard, by stope connection roadway, slice drift, segmentation, join lane by ore body and stage haulage way or ramp UNICOM; In the first segmentation bottom, form pulling end space and construct artificial false bottom, for the rock drilling space that upright opening is provided is exploited in this segmentation; By back production dividing elements, be upright opening and two back production regions of lateral aperture, the most of ore body in back production unit, vertical Luo Kuang hole, unit top board is pressed to adopt by lateral aperture and is formed, and unit two helps profile to be controlled by vertical pre-ceasma; Pressure is protected top operation after adopting end, adopts subsequently Common LHD and remote-controlled scraper to work in coordination with ore removal, goaf, unit primary filling, and on adopt next segmentation and leave rock drilling space, so circulation, until a whole step stope mining is complete.
Further, two of two back production regions of upright opening and lateral aperture help profile to be controlled by vertical pre-ceasma onepull, and upright opening, pre-ceasma detonate with vertical Luo Kuang hole homogeneous simultaneously.
Adopt the upright opening of technique scheme and the mechanization sublevel cut and fill method of the collaborative back production of lateral aperture, the problems referred to above that exist in recovery process for sublevel fill stoping method, the mechanization sublevel cut and fill method of the collaborative back production of upright opening and lateral aperture is creatively proposed, guaranteeing under the prerequisite of job safety, realizing the safe and efficient low-cost exploitation of big thick ore body.
Adopt the present invention, beneficial effect is:
1. stoping safety is high
By back production dividing elements, be upright opening and two back production regions of lateral aperture, the miner that falls does the major part that upright opening region completes this segmentation, and by presplit blasting, control back production unit two and help profile, lateral aperture back production region is pressed and is adopted operation on upright opening shrink heap, and by controlled blasting controlroof profile.
2. back production efficiency is high, production capacity is large
Segmentation is exploited, and has greatly improved back production efficiency and the production capacity of stope,
3. mechanization degree is high, labour intensity is low
Trackless is adopted standard, and the use of the advanced trackless extractive equipments such as jumbo, remote-controlled scraper, electric truck, rock bolting jumbo, whitewashing chassis has greatly improved the mechanization degree of producing, and has greatly reduced workman's labour intensity.
4. adopt cost low, resources loss is few
Accurate cutting is adopted in segmentation, substoping, and sublevel fill stoping, technique is simple, and cost is low; Can serialization exploit, resources loss is few.
The present invention had both brought into play the high strength, high efficiency of minute section mining, feature cheaply, utilized again presplit blasting to control the profile that substoping unit two is helped, and was pressed and was adopted the profile of having controlled back production unit top board simultaneously by lateral aperture.That the present invention has is safe and efficient, technique is simple, the little and high advantage of mechanization degree of loss and dilution.
In sum, the present invention is a kind of assurance under the prerequisite of job safety, realizes the upright opening of safe and efficient low-cost exploitation and the mechanization sublevel cut and fill method of the collaborative back production of lateral aperture of big thick ore body.
