Detailed description of the invention
To be described in further detail the utility model embodiment below.
Of the present utility modelly move towards shortwall shearing formula hydraulic support, its preferably detailed description of the invention be:
Comprise lane support and lower lane support, the front portion of described support rear portion, upper lane and lower lane support is respectively equipped with leading block, in described upper lane support and lower lane support, at least one support is provided with winch, described leading block walked around by haulage cable on described winch, and described haulage cable is provided with rope saw.
The front portion of described support rear portion, upper lane and lower lane support is respectively equipped with two leading blocks, and described winch is double-drum winch, and described haulage cable has two, every bar haulage cable is respectively equipped with rope saw.
Described rope saw is two-way rope saw, and the front portion of described upper lane support is provided with winch, and the bottom of described lower lane support is provided with scratch board conveyor.
Described two-way rope saw comprises the cutting drum of two tapers, and the bottom of two cutting drums is hinged, and the side of two cutting drums is respectively equipped with pick box, and described pick box is equipped with pick, and the top of two cutting drums is respectively equipped with wire rope hold down gag.
The inside of described cutting drum is located at by described wire rope hold down gag.
Described upper lane support and lower lane support are respectively puts down hydraulic support gently.
The shortwall shearing formula hydraulic support that moves towards of the present utility model realizes the method that Sub-Level Caving mines and is:
Winch drives haulage cable to make rope saw the rib compressed between Shang Xiang and lower lane and does cutting movement, and coal body is pulled out groove by rope saw, and make top-coal control, coal seam is gradient coal seam thickness all coal seams below 8 meters more than 45 °.
First by rope saw, coal body is pulled out two grooves, along with intensification two groove coals of groove will be caving voluntarily, so latter two groove will form a large groove, form face-airing eye, the top coal of large groove both sides, by releasing under roof and floor pressure and the deadweight of coal and the effect of lower lane hydraulic support, realizes coal breakage with this.
Sub-Level Caving lower lane support tail end with under lane scratch board conveyor transport.
Of the present utility modelly move towards shortwall shearing formula hydraulic support, with reference to gently inclined thin seam coal plough shearing technological principle, the planing tool of coal plough is changed into the rope saw that is equipped with multiple sawtooth, two ends wire rope connects, cancel coal plough to run on fixed guide, employing steel cable flexible draws, rope saw comprises the broken coal cutter of two-ways coal cutting, broken coal cutter there is two-way pick, rope saw is connected with haulage cable, wire rope is by upper and lower lane support four leading blocks, be connected with the double-drum winch in the support of upper lane, winch drives haulage cable that rope is sawed and compresses rib, do up and down reciprocatingly cutting movement, coal body is just pulled out two grooves by rope saw, along with intensification two groove coals of groove will be caving voluntarily, so latter two groove will form a large groove, form face-airing eye, top, large groove both sides ground coal, by roof and floor pressure and coal deadweight and released by support under the effect of rear hydraulic support, coal breakage is realized with this.Sub-Level Caving lower lane support tail end with under lane scratch board conveyor transport, this coal-mining method work plane non-support, workman can not enter work plane, realize unmanned coal face mining, only in upper and lower lane, start winch traversing carriage, the labour intensity of workman can be alleviated, improve work efficiency.
Advantage of the present utility model:
1, the upper and lower lane of work plane all uses and puts down hydraulic support gently, and supporting is safe and reliable, is convenient to production safety management, workable, and work plane non-support, personnel realize manless working face in the operation of upper and lower lane.
2, this coal winning technology is simple: prepare, and--saw coal--is put, is transported coal--and moves frame, and personnel are few, labour intensity is little, efficiency is high, material consumption is low reduces cost of ton coal expense.
3, decrease perforating, powder charge, blow out, the operation of Advance presplitting, solve in priming system use management and hidden danger in blowing out.
4, single face output can significantly improve, and estimates that this working surface production ability can arrive monthly output more than 2.3 ten thousand tons/month, can realize high-yield and high-efficiency.
5, not at construction ventilation eye, can reduce headwork amount 250m, excavation work amount significantly reduces, and reduces by ten thousand tons of drivage ratios, is conducive to alleviating mine and continues nervous situation.
6, can to realize and coal seam Advance Water Injection combines, to reach the effect of softening coal body, release coal gas, depositing dust.
7, most importantly ventilation system is reasonable, and two enter one time, fundamentally solve the difficult problem that Top Corner Gas on Coal Face transfinites, and decrease upper and lower lane auxiliary ventilator air feed.
8, this coal-mining method can realize all coal seams long-mining of more than 45 ° thickness below 8 meters, practical.
The above; be only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
