Abstract
The invention discloses a fast installation method of ten-million-ton scale fully mechanized caving face equipment and belongs to sinking and driving engineering of mines. The method is innovatively characterized in that open-off cuts on a working surface are widen to improve the transportation mode and installation method of a hydraulic support and the supporting mode of the open-off cuts. By virtue of the improvements, the installation time of the ten-million-ton scale fully mechanized caving face equipment is realized, the construction period is shortened and the installation progress of the working surface is accelerated.
Description
Technical field
The present invention relates to mine tunnel engineering, be mainly used in fully mechanized coal face and cut the expansion of eye brush and equipment installation project.
Background technology
At present, the colliery ten-million-ton scale is combined and to be adopted, when fully mechanized coal face equipment is installed, and at first the construction working face is cut eye, because equipment is huge, cut a span generally at 8-10m, cut the eye construction back that finishes and adopt the individual prop align reaming to connect back timber it is added strong supporting, and then carry out the working face equipment installation work.Remove individual prop again when equipment is installed, be changed to fully mechanized mining supporter.
Brought the problem of following three aspects thus:
(1) work plane cut the eye fully the construction finish the back span bigger, workload is big when adopting individual prop to add strong supporting, need set more than 1000 of individual prop, and installation period is grown the difficulty height, and the operating space that hydraulic support is installed is little, causes potential safety hazard to roof control.
(2) cut equipment such as carrying out hydraulic support after the eye construction finishes again at work plane and install, cause the work plane set-up time longer, influence the operation progress.
(3) because the hydraulic support transit route is longer, adopt the monorail crane travelling speed slower, adopt bracket carrier to harden to the transit route base plate separately, workload is big, and the duration is longer.Resistance is bigger when using winch haul support, and is more serious to roadway floor destruction, and transportation safety is caused big hidden danger.
Summary of the invention:
The present invention provides a kind of ten-million-ton scale fully mechanized coal face equipment method for rapidly mounting for addressing the above problem.
Mounting method of the present invention is as follows:
After the upper and lower gallery developing in exploiting field, at wide 4.5 meters, high 3.7 meters common eye of cutting of pre-mining face developing, form ventilation circulation system; It is characterized in that,
(1) the hydraulic support transportation resources is:
(1) hydraulic support is split aboveground, after the shaft station re-assemblies, transport to and change the outfit a little, adopt directly hydraulic support to be transported to after the bracket carrier entrucking and cut a upper end.Three is one group during unwheeling carrying hydraulic support, the safety when guaranteeing the transportation of upper and lower slope;
When (2) bracket carrier is carried, lay hinged viaduct at gate top, hinged viaduct adopts i iron and checkered plates to be welded into a piece bed board, and is hinged again, is layered on the gate top road surface, and the viaduct surface increases rubbing surface and props up a unwheeling climbing capacity to improve;
(3) upper end of autotomying is laid slide plate downwards along work plane, to reduce the friction of hydraulic support and base plate; After hydraulic support arrives upper end, utilize winch to adjust the direction of hydraulic support, guarantee that the hydraulic support direction is parallel with work plane, and hydraulic support is adjusted to the slide plate center; Reduce the hydraulic support height, its center of gravity is descended, occur the phenomenon that skews when avoiding with winch pull-down hydraulic support; Cutting winch of tip placement now, hydraulic support is pulled down to the installation site along slide plate;
(2) cut the wide and hydraulic support installation construction synchronously of eye brush
(1) cut now the termination from work plane and begin its brush widely, brushing wide degree is 5.3m, forms the width spaces that is easy to install hydraulic support of 9.8 meters of width;
(2) after cutting the wide 30 meters length of eye brush, begin to install hydraulic support; Earlier advance timbering is moved to new position, vacates the position of hydraulic support, with hydraulic support is drop-down put in place after, utilize that tail boom and plate cooperate winch that the hydraulic support direction is adjusted to and the work plane upright position behind the hydraulic support.All this group hydraulic support is carried out fluid injection behind one group of hydraulic support of every installation, guarantee that the hydraulic support setting load reaches 24Mpa, opens hydraulic support extensible canopy and face guard simultaneously; The limit is installed the hydraulic support limit and is brushed the wide eye of cutting, the limit secondary supporting, and advance timbering is removed on the limit, and order is carried out, and installs until entire working surface equipment;
(3) cut the eye supporting method be:
(1) at first driving is cut a top board and is selected for use the left-handed high strength anchor bar of KMG500 Φ 22 * 2500mm to join the supporting of W steel band compressed steel muscle weldering net, and array pitch is 850 * 1000mm between the left-handed high strength anchor bar of KMG500 Φ 22 * 2500mm; Two help to adopt Φ 22 * 2500mm Bolt with Full Screw Threads and Equal Strength to join the W steel band presses two anti-net supportings, and array pitch is 750 * 1000mm between Φ 22 * 2500mm Bolt with Full Screw Threads and Equal Strength; First anchor cable is arranged in the top board place between the steel band of tunnel, the construction of jacking coal, and an array pitch is 2250 * 2000mm; The first anchor cable length 10.3m;
(2) the wide top board of cutting of secondary brush selects for use the left-handed high strength anchor bar of Φ 22 * 2500mm to join the supporting of W steel band compressed steel muscle weldering net, and array pitch is 900 * 1000mm between the left-handed high strength anchor bar of Φ 22 * 2500mm; The group's face after wide brushed adopts Φ 22 * 2500mm Bolt with Full Screw Threads and Equal Strength to join the W steel band and presses two anti-net supportings, array pitch 850 * 1000mm between Φ 22 * 2500mm Bolt with Full Screw Threads and Equal Strength anchor pole; When running into breaking roof, top board adopts second anchor cable to add strong supporting, and the second anchor cable specification is Φ 18.9 * 10.3m, and an array pitch is 2250 * 1000mm; Immediately following driving face, install row's individual prop and add strong supporting along a former center line of cutting, up along with the brush width position, along arranging in the lane that two row's advance timberings carry out supporting, an array pitch is 1m at the rear portion.
Beneficial effect of the present invention:
(1) optimizes the roof timbering scheme of cutting of the nearly 10 meters big sections of width, cancelled top board anchor cable truss and added strong supporting and hydraulic pressure monomer reinforce support, reduced site operation labour intensity, reduced the supporting expense.Realize the support installation simultaneously and cut the parallel operations that the eye brush expands, guaranteed to install every day 4-5 frame support, shortened construction period, accelerated the work plane installation progress.
(2) if transport according to original method, need harden to roadway floor, the required duration has relatively high expectations than long and hardening strength, and the later stage need keep in repair.And after adopting bracket carrier to cooperate this mode of the hinged viaduct of steel plate, hinged viaduct intensity can satisfy movement requirement, has both improved travelling speed, has saved the time, can avoid waste of material again.
(3) slide plate cooperates the application of the means of transportation of winch, has also improved and has cut a safety of position support transportation, has avoided " eating the end " phenomenon in the transportation, has reduced the destruction to the tunnel.
