Abstract
The present invention is a kind of anti-method killed of Full-mechanized mining working face ended support, the specific steps are as follows: (1) advanced frame to the single anchor cable of face end support people's row side complement；(2) advanced frame remains that forward tunneling boring is acted as a planted agent；(3) increase double individual prop before advanced frame as advance support；(4) timely complement anchor cable before advanced frame；(5) it is fallen by the way of planted agent to elevating conveyor at the face end support killed.The present invention takes the top plate before face end support and reinforces in advance, it can prevent top plate from further sinking, bigger pressure is generated to face end support, is acted as a planted agent in advance, it is ensured that face end support stroke, both it is crushed to death to face end support and plays prevention effect, it is handled killed to face end support again after, plays positive effect, take and act as a planted agent to elevating conveyor at face end support, the destruction generated to roof blasting is alleviated, the face end support that processing is crushed to death is more advantageous to.
Description
Technical field
The present invention relates to coal mining fields, and in particular to a kind of anti-method killed of Full-mechanized mining working face ended support.
Background technique
Coal mine fully-mechanized mining working faces end head bracket is in and cuts eye and haulage gate region of stress concentration, when periodic weighting or top plate
When being crushed serious, it may occur that leakage emits type or push engine, so that Full-mechanized mining working face ended support is killed, causes face end support
Column does not have stroke that can not move.After previous method is mostly hydraulic support pushed down, takes and explosion is carried out to top plate above face end support
The method of unrestrained spoil restores face end support column stroke, but when top plate is extremely broken, explosion makes top plate more broken instead
Broken more unfavorable to bracket is restored, processing face end support kills more difficult, it is seen that this method has topical type.Need a kind of synthesis
The method that prevention and processing face end support are crushed to death.
Summary of the invention
Technical problem to be solved by the present invention lies in view of the above shortcomings of the prior art, provide a kind of fully-mechanized mining working
The anti-method killed of face end support.
To solve the above problems, the present invention proposes a kind of anti-method killed of Full-mechanized mining working face ended support, specific steps
It is as follows: (1) advanced frame to the single anchor cable of face end support people's row side complement；(2) advanced frame remains that forward tunneling boring is acted as a planted agent；
(3) increase double individual prop before advanced frame as advance support；(4) timely complement anchor cable before advanced frame；(5) using sleeping
The mode at bottom falls to elevating conveyor at face end support.
The step (1) method particularly includes: in advanced frame to the single anchor cable of the timely complement in the end side Jia Renhang, prevent from pushing up
Plate further sinks, and specification chooses 18.9 ~ 21.6mm of Φ, the anchor cable of 7.1 ~ 8.8m of length.
The step (2) requires are as follows: 100 ~ 200m range remains that tunneling boring is acted as a planted agent to advanced frame forward, it is ensured that end branch
There are enough strokes in frame progradation, will not be killed easily, the roadway floor after planted agent cannot be less than setting to ceiling height
Meter height.
The step (3) increases double individual prop as advance support before advanced frame, increases individual prop range not
It obtains and is less than 100m.
The step (4) timely complement anchor cable before advanced frame, further controlroof sink, the anchor cable quantity root of complement
It is designed according to heading sizes.
The step (5) forbids to discharge face end support row by the way of to roof blasting after face end support is crushed to death
Journey falls to the elevating conveyor at face end support by the way of planted agent, to discharge face end support stroke.
Compared with the prior art, the present invention has the following advantages.
The present invention takes the top plate before face end support and reinforces in advance, can prevent top plate from further sinking, to face end support
Bigger pressure is generated, is acted as a planted agent in advance, it is ensured that face end support stroke is both crushed to death to face end support and plays prevention effect,
It is handled killed to face end support again after, plays positive effect；It takes and acts as a planted agent to elevating conveyor at face end support, alleviate
To the destruction that roof blasting generates, it is more advantageous to the face end support that processing is crushed to death.
Invention is further described in detail with reference to the accompanying drawings and examples.
Detailed description of the invention
Fig. 1 is flow chart of the present invention.
Specific embodiment
Example is the anti-method killed of certain mine Full-mechanized mining working face ended support, according to Fig. 1, the specific steps are as follows: (1)
Advanced frame is to the single anchor cable of face end support people's row side complement；(2) advanced frame remains that forward tunneling boring is acted as a planted agent；(3) super
Increase double individual prop before side arm as advance support；(4) timely complement anchor cable before advanced frame；(5) by the way of planted agent
It falls to elevating conveyor at face end support.
Step (1) is to prevent top plate from further sinking, in advanced frame to the single anchor cable of the timely complement in the end side Jia Renhang,
Specification chooses Φ 21.6mm, the anchor cable of length 8.8m.
In advanced frame, 100m range remains that tunneling boring is acted as a planted agent to step (2) forward, the roadway floor after planted agent to top plate
Height 3.8m is greater than former design height 3.6m.
Step (3) increases double individual prop as advance support before advanced frame, and increasing individual prop range must not lack
In 150 ~ 100m.
Step (4) timely complement anchor cable before advanced frame, further controlroof sink, between the anchor cable number of complement uses
1.4 × 1.4m of array pitch, tunnel clear span 5.6m, every row 3.
Step (5) is forbidden to discharge face end support stroke by the way of to roof blasting after face end support is crushed to death,
It by the way of planted agent, falls to the elevating conveyor at face end support, to discharge face end support stroke.
All any simple modification, change and equivalence change to the above embodiments according to the present invention, still belong to
In in protection scope of the present invention.
