Abstract
The invention relates to a convenient segmented support method for a mine slant chute comprising following steps: (1) the stability of a wall of the slant chute is calculated and analyzed to determine a support form according to the actual construction situation; (2) a chute link lane is dug every 15 meters downwards from the mouth of the well in the slant chute; (3) the slant chute is filled with backfill slag until the distance between the surface of the backfill slag and the well mouth is 2 meters, then wood boards are laid on the upper surface of the backfill slag inside the well and construction workers perform support construction operation sanding on the wood boards; (4) slag removal is performed in a next segmented chute link lane until the slag level inside the chute decreases by 2 meters; (5) construction workers perform the next support construction operation; (6) step (4) and (5) are repeated until the construction work is completed. The support method of the invention has the following beneficial effects: (1) the slant chute is filled with slag, slag is discharged by several times, support is performed by several times and the support circulation are continued until the slag surface level decreases to the completion of the slant chute support; (2) the safety factor is high.
Description
Technical field
The invention belongs to energy extraction field is and in particular to mine slant chute portable sectional supporting
Method.
Background technology
At present, how due to rock crusher, construction and supporting operation are difficult, slip for domestic underground mine
After the completion of well construction, due to rock crusher in Bracing Process, drop shaft Sidewall Surrounding Rock exposed area and
Space is larger, and operating personnel and construction equipment, equipment are caused with security threat, inconvenience construction.
There is many unfavorable factors during supporting, often result in that the duration is longer, potential safety hazard is many,
This to mine safety construct produce, and adopt, select etc. each system steady production more unfavorable, ore deposit
Mountain overall efficiency impact is larger.
At present, big-and-middle-sized underground mine drop shaft method of support both at home and abroad, mostly suspended bulkhead raising method or overall
The method for protecting support such as sliding formwork, the method is suitable for the preferably perfectly straight well supporting of drop shaft Sidewall Surrounding Rock.Country rock
Broken slant chute cannot be using suspended bulkhead raising method, overall slipform process, and Sidewall Surrounding Rock exposed area
Greatly, inspection sled Pumex is difficult, and Sidewall Surrounding Rock slump is larger.
Content of the invention
Goal of the invention: the problem that the present invention is directed to above-mentioned prior art presence makes improvement, that is, originally
Disclosure of the invention mine slant chute portable sectional supporting method.
Technical scheme: mine slant chute portable sectional supporting method, comprise the following steps:
(1), according to actual condition of construction, according to existing stability of the hill analysis method,
The stability of the borehole wall of drop shaft is carried out calculating analysis, determines support form；
(2), the well head in slant chute digs a drop shaft connection lane every 15 meters downwards, and drop shaft joins
Lane is communicated with slant chute, ground respectively；
(3), with backfill quarrel filling slant chute, until the surface of backfill quarrel is till well head 2m；
Backfill quarrel upper surface laying plank in well, workmen steps down in and carries out supporting construction work on plank
Industry；
(4), muck removal is carried out in the drop shaft connection lane of next segmentation using underground trackless scraper,
Till the quarrel position in drop shaft declines 2m；
(5), workmen steps down in and carries out next supporting construction operation on plank；
(6), repeat step (4)～(5), till fulfiling assignment.
Further, the supporting construction operation in step (3) comprises the following steps:
(31), first the Pumex of the drop shaft borehole wall is carried out with inspection sled,
(32), sprayed concrete supporting temporarily,
(33), after basic security, construction bolthole carries out suspension roof support,
(34), bar-mat reinforcement is worked out on the drop shaft borehole wall, by bar-mat reinforcement and the anchor pole welding exposing
For together；
(35) outside of next-door neighbour's bar-mat reinforcement is set up support template, then pour in support template
Concrete, after concrete setting, removes support template.
Further, the anchor pole in step (33) is the screw-thread steel that diameter 18mm length is 3m.
Further, described anchor pole injects well wall body 2.7m, exposes 0.3m.
Further, the spacing of the bar-mat reinforcement in step (34) is 0.3m*0.3m.
Beneficial effect: mine disclosed by the invention slant chute portable sectional supporting method have with
Lower beneficial effect:
(1), drop shaft fills out quarrel, puts quarrel, graded supporting by several times, and supporting circulation drops to quarrel face
Drop shaft supporting completes；
(2) what, the slant chute of rock crusher was safe and reliable carries out supporting, in Bracing Process not only
Do not affect progress, and safe and reliable it is achieved that larger safety benefit, social benefit.
