Abstract
The invention relates to the field of underground coal planer working face exploitation in a coal mine, in particular to a coal clearing end support used for a working face of a coal planer and a coal clearing method and solves the problem that coal accumulates at the machine head and the machine tail, particularly the machine tail, of the working face of the coal planer. The coal clearing end support comprises a top beam, a first-level jack, a first-level coal clearing plate, a second-level coal clearing plate, a small connecting bar and a second-level jack, and the first-level coal clearing plate, the second-level coal clearing plate, the second-level jack and the small connecting bar form a four bar mechanism; the length of the first-level coal clearing plate is less than or equal to that of the second-level coal clearing plate, the sum of the lengths of the first-level coal clearing plate and the second-level coal clearing plate is larger than the thickness of a coal seam, so that the coal clearing scope of the second-level coal clearing plate is large, and coal at the machine head and the machine tail of the coal planer are better cleared away. According to the coal clearing end support, the operation is simple, the coal clearing effect is good, no additional operators are required, the labor intensity and unsafe factors of manual coal clearing are reduced, and the high-yield and high efficiency exploitation requirements of the coal mine are satisfied.
Description
Technical field:
The present invention relates to underground coal mine Particleboard performance exploitation field, specifically a kind of clear coal face end support for Particleboard performance and clear coal method.
Background technology:
At present, Particleboard performance is that resistance type is coaling, namely the coal that gets off of planing is more long-pending higher in the effect Xia Pao road of planer head forward thrust and rib restriction, enters in coal plough chute transported when coal piling reach a certain height under the effect of planer head thrust along planer head plow-shape face.At coal plough head tail, owing to there being the existence of crossheading, the residing space after losing rib restriction of the coal in plane road becomes suddenly large, part of coal enters into crossheading, and along with the continuous propelling of work plane, coal piling phenomenon progressively appears in coal plough head tail, especially tail position, coal piling is more serious.Position, termination is the passage of work plane transport, and serious coal piling brings inconvenience to the transport of equipment auxiliary material; Coal piling is too high simultaneously can affect dash net section, unfavorable to face-airing; Head tail coal piling also makes local, position, termination propelling resistance increase, and advancing equipment has impact.The clear coal method of tradition is based on irregular artificial clear coal, and labor strength is large, and clear coal efficiency is low, is unfavorable for that colliery realizes safety, exploits high-yield and high-efficiency.
Summary of the invention:
The object of the present invention is to provide a kind of clear coal face end support for Particleboard performance and clear coal method, solve Particleboard performance head tail, the especially problem of tail coal piling.
The technical solution used in the present invention is: a kind of clear coal face end support for Particleboard performance, comprises back timber 1, one-level jack 2, one-level clear coal plate 3, the clear coal plate 4 of secondary, small rod 5 and secondary jack 6.One-level clear coal plate 3, the clear coal plate 4 of secondary, small rod 5, secondary jack 6 form quadric chain, the length L of the clear coal plate of one-level
1the length L of the clear coal plate of≤secondary
2, the length sum L > coal seam thickness L of one-level clear coal plate and the clear coal plate of secondary
m.
Further, one-level clear coal plate 3, secondary clear coal plate 4, secondary jack 6 be all hinged with small rod 5.
There is provided a kind of clear coal method, adopt clear coal face end support as above, the method comprises: support is in supporting state, and the clear coal plate 4 of secondary is regained completely, regains the clear coal plate 3 of one-level and shifts onto in chute D by coal mound top B; Launch one-level clear coal plate 3 and the clear coal plate 4 of secondary successively, then one-level clear coal plate 3 moves to suitable position, regains secondary clear coal plate 4 and is shifted onto in chute D by coal mound bottom C.
Beneficial effect of the present invention shows: requisite for Particleboard performance functions of the equipments expanded, " gathering materials on the spot ", face end support possesses coal function clearly while supporting, can with the mechanization of support electricity hydraulic control integration realization, automation regularly clear coal.This clear coal face end support supporting area is large, and simple to operate, clear coal is effective, without the need to newly-increased operator, reduces labour intensity and the unsafe factor of artificial clear coal, meets the exploitation requirement to colliery high-yield and high-efficiency.
Accompanying drawing illustrates:

Detailed description of the invention:
As shown in Figure 1, this support comprises back timber 1, one-level jack 2, one-level clear coal plate 3, the clear coal plate 4 of secondary, small rod 5 and secondary jack 6.The clear coal plate 3 of the hinged one-level in back timber 1 front end, the hinged one-level jack 2 of middle front part, the other end of one-level jack 2 and one-level clear coal plate 3 hinged, the clear coal plate 3 of one-level can be promoted and open and regain; The clear coal plate 4 of the hinged secondary of one-level clear coal plate 3 and secondary jack 6, three is all hinged with small rod 5, forms quadric chain, realizes the function of the clear coal of digging type; The length sum L > coal seam thickness L of one-level clear coal plate and the clear coal plate of secondary
m, and the length L of the clear coal plate of one-level
1the length L of the clear coal plate of≤secondary
2, the clear coal scope of the clear coal plate 4 of secondary is strengthened, better to remove coal mound bottom C.
As shown in Figure 2 and Figure 3, a kind of method adopting the clear coal of above-mentioned support, when work plane head tail coal piling is serious, for reducing clear coal resistance, adopt the method for segmentation cleaning, supporting state after face end support is in and tries to stop people from fighting each other, the clear coal plate 4 of secondary is regained completely, one-level jack 2 drives the clear coal plate 3 of one-level to push in chute D by coal mound top B, then one-level clear coal plate 3 and the clear coal plate 4 of secondary is launched successively, one-level jack 2 pulls the clear coal plate 3 of one-level to correct position, regains secondary clear coal plate 4 and is pushed in chute D by coal mound bottom C, thus reach the effect of the clear coal of head tail.
Schematic but not pro forma restriction by preferred embodiment to the detailed description that technical solution of the present invention is carried out above.Those skilled in the art is on the basis of reading manual of the present invention, technical scheme described in embodiment can be modified, or equivalent replacement is carried out to wherein portion of techniques feature, and these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of embodiment of the present invention technical scheme.
