Specific embodiment
Below with reference to specific embodiment, the present invention is described in further detail, it is described be explanation of the invention and
It is not to limit.
This example is illustrated technical solution of the present invention by taking right working face as an example.
1, hydraulic support operation technique:
The program that hydraulic support is set according to SAC electrohydraulic control system moves frame with machine automatically, elapses drag conveyor, receives
Face guard is beaten, specific as follows:
First stage: coalcutter is from tail to the normal coal cutting of head, and coalcutter front roll at least one bracket distance is received in advance
Face guard, lag coalcutter back roll at least 2 frame bracket distances stretch face guard, try to stop people from fighting each other in coalcutter fuselage center, lag
At least Z meters of passage drag conveyor of coalcutter back roll；Wherein Z meters are two fuselage lengths；
Second stage: the saturating coal wall of coal mining machine cut tries to stop people from fighting each other to the stopping of X frame with machine and tries to stop people from fighting each other, lags one machine of coalcutter back roll
Body length stops passage drag conveyor, and drag conveyor is bent segment length and is not less than a fuselage length, passes through patrolling for installation
It collects passage valve control bending section passage drag conveyor and elapses stroke, it is ensured that bending section transition is gentle, and X is the saturating coal wall of coal mining machine cut
Stop frame number and clear float coal retreats the sum of frame number；X frame is No. 15 framves in this example, and bending section most after-frame is No. 30 framves, such as Fig. 1 and
Shown in Fig. 2；
Phase III: coal mining machine cut ground coal, clear float coal.
Fourth stage: after the completion of clear float coal, coalcutter is run to tail, and first middle bracket of head to X ' frame is moved with machine
Frame enters straightway to coalcutter beveling feed, and successively total travel elapses drag conveyor to bending section bracket to first bracket, complete
Frame is moved at follower head frame and transition frame sequence, wherein X '=X-1；In this example, specifically, coalcutter is run to tail, 6-14
Number frame moves frame with machine, enters straightway, the successively total travel passage scraper plate conveying of No. 30 framves to No. 1 frame to coalcutter beveling feed
Machine, 1-5 frame sequence moves frame after the completion, as shown in Figure 3 and Figure 4；
5th stage: coal mining machine cut Triangle Coal cuts ground coal, as shown in Figure 5；
6th stage: the clear float coal of coalcutter, as shown in Figure 6；
7th stage: after the completion of clear float coal, coalcutter is run to tail, and hydraulic support shifts to an earlier date coalcutter front roll at least 1
A bracket distance receives face guard, and lag coalcutter back roll at least 2 frame bracket distances stretch face guard, in coalcutter fuselage centre bit
It sets sequence to try to stop people from fighting each other, as shown in Figure 7；
8th stage: coalcutter is run to tail to Y frame, and total travel elapses drag conveyor since head, after the completion
End frame and transition frame sequence move frame, and Y frame is that head counts bracket at two fuselage lengths, this example is No. 27 framves, such as Fig. 8 institute
Show；
9th stage: coalcutter is operated normally to tail, and coalcutter front roll at least one bracket distance receives wall supporting in advance
Plate, lag coalcutter back roll at least 2 frame bracket distances stretch face guard, try to stop people from fighting each other in coalcutter fuselage center, and lag is mined
At least Z meters of passage drag conveyor of machine back roll, as shown in Figure 9；Wherein Z meters are two fuselage lengths.
Feed hydraulic support operation technique in tail end is same as mentioned above, wherein X is that the saturating coal wall of coal mining machine cut stops
Frame number and clear float coal retreat the difference of frame number, X '=X+1, and Y frame is that tail counts bracket at two fuselage lengths.
2, coalcutter operation technique
Coalcutter cuts the operation of Triangle Coal lead according to traditional end and remembers automatically according to the mining height data of demonstration knife record
Recall cutting, as shown in Figure 10.
First stage: coalcutter is from tail to head coal cutting, and the cylinder that rolls left is along vertex cut top coal, and right roller is along undercut ground coal.
Second stage: coalcutter is run to tail direction, and right roller is centrally located, rolls left cylinder under, range ability
For a fuselage length, net ground coal is cut.
Phase III: coalcutter is run to heading, and right roller is centrally located, rolls left cylinder under, clears up float coal.
Fourth stage: coalcutter is run to tail direction, and right roller is located at centre, rolls left cylinder under, into after bending section,
Right roller rises, and chamfers feed.
5th stage: coalcutter cuts Triangle Coal to head operation.Right roller is under at this time, and the cylinder that rolls left is upper, until cutting coal
Wall.
6th stage is identical as second stage, and the 7th stage is identical as the phase III.
8th stage: coalcutter is run to tail direction, and right roller is centrally located, cylinder is rolled left under, into knife stubble
Afterwards, top coal is cut in right roller rise, and the cylinder that rolls left cuts ground coal, operates normally.
Feed coalcutter operation technique in tail end is same as mentioned above.
The present invention high working face intelligence end feed there are aiming at the problem that, the present invention provides a kind of intelligent end of optimization
Head feed technique, by adjusting coalcutter run posture, hydraulic support sequence of movement, can from the time, spatially solve hydraulic branch
The problem of frame, coalcutter, drag conveyor interfere.
