Description
Technical field
Patent of the present invention relates to a kind of roadway arrangement shape of colliery, is specially a kind of big U and overlaps the tunnel that little u mode is arranged.
Background technology
Generally adopt process for stoping in the China's coal-mine down-hole coal excavation process at present, the roadway workface arrangement that matches has multiple roadway arrangement modes such as " U " type, " U+L " type, " U+I " type, under the present low gas condition, can satisfy substantially and produce needs, but under high gas condition, the driving of gate road and stope ventilating gas all exist the drawback that self is difficult to overcome on administering.
Summary of the invention
Patent of the present invention provides the big U of stope under a kind of high gas condition to overlap the tunnel that little u mode is arranged for the problem that solves the crossheading driving that exists in the set-up mode of existing tunnel and stope gas control.
Patent of the present invention is realized by following technical scheme, a kind of big U overlaps the tunnel that little u mode is arranged, comprise stope, get the peripheral little u tunnel that is provided with at stope, described little u tunnel is the belt lane of stope both sides, return airway, the stope front side cut eye, arranged outside in little u tunnel has big U tunnel, described big U tunnel is equipment and the ventilation lane that head and the tail connect, air connection, gas tail lane, equipment and ventilation lane are positioned at the outside, belt lane, air connection is positioned at cuts the eye outside, and gas tail lane is positioned at the return airway outside, is provided with some entities between big U tunnel and the little u tunnel and supports coal column.
According to structure of the present invention that little u tunnel and big U tunnel initating is good, begin back production then, little u tunnel collapses thereupon when work plane pushes away later, and remaining of big U tunnel energy success is this work plane and adjacent work plane service.Have the following advantages specifically:
1, helps realizing two lanes driving technology, improve gas control ability in the crossheading tunneling process.Because the coal body gas emission is big under the highly gassy mine, " U " type in the past, " U+L " type, " U+I " type setting and cause to such an extent that the long distance driving in single lane often gas exceeding limit occurs and is forced to stop dig phenomenon, simultaneously in case the blowing-out phenomenon occurs, whole piece tunnel gas density with and can rise and form a very big gas storehouse, bring very big hidden danger to drawing-off gas and safety management, structure by little u and the big U two lanes driving that forms arranged side by side, can in time form full blast presses, press tunnel gas by the big air quantity dilution of high negative pressure full blast, dwindle the distance of local fan ventilation, realize the continuous driving in tunnel, improve drivage efficiency.
2, solve the difficult problem of stope gas control problem.
After adopting big U to overlap the structure tunnel of little u this setup, in four gate roads that both sides form, two is the air intake lane, and outer two is not return airway, helps improving the wind supply quantity of stope on the one hand; Another side gas tail lane be in all the time full blast press distinguished and admirable in, make things convenient for personnel to enter the operation of rear portion, goaf, can also carry out the goaf extraction by horizontal river, tail lane, rear portion.
3, owing to two tunnels of big U in " four lanes layout " want secondary to use at the adjacent face of adopting,, reduced the roadway engineering amount of the face of adopting, reduced by ten thousand tons of drivage ratios from long-range angle.
4, can realize laddering extraction, the lane of staying owing to big U tunnel can provide room and time for adjacent face gas extraction, makes tunnelling carry out under the present low gas condition, realizes that pumping, excavation, mining truly are connected normal.

Fig. 3 is an of the present invention pair of lane driving arrangement schematic diagram
Among the figure: 1-stope, 2-ventilation lane, 3-belt lane (air intake hold concurrently belt crossheading), 4-air connection, 5-cut eye, 6-gas tail lane, 7-return airway (the assistant conveyance crossheading of holding concurrently), 8-entity and support coal column, the horizontal river of 9-, the horizontal river of 10-, 11-belt go down the hill passage, 12-air intake hold concurrently assistant conveyance go down the hill passage, 13-return air go down the hill passage, the airtight divider wall of 14-, the airtight divider wall of 15-, 16-goaf
The specific embodiment
A kind of big U overlaps the tunnel that little u mode is arranged, as schematically shown in Figure 1, comprise stope 1, get the peripheral little u tunnel that is provided with at stope 1, described little u tunnel is the belt lane 3 of stope both sides, return airway 7, the stope front side cut the eye 5, arranged outside in little u tunnel has big U tunnel, described big U tunnel is equipment and the ventilation lane 2 that head and the tail connect, air connection 4, gas tail lane 6, equipment and ventilation lane 2 are positioned at 3 outsides, belt lane, air connection 4 is positioned at cuts eye 5 outsides, and gas tail lane 6 is positioned at return airway 7 outsides, is provided with some entities between big U tunnel and the little u tunnel and supports coal column 8.
Be provided with 35 meters thick entities between big U tunnel and the little u tunnel and support coal column 8, simultaneously big U tunnel arranges that along roof little u arranges along seat earth in the tunnel.Article two, the air intake lane promptly ventilate lane 2, belt lane 3, between the gas situation of horizontal river 10 spacings during according to driving, one of every 100-200 rice construction is to guarantee the requirement of two lanes driving.Article two, return airway be gas tail lane 6, return airway 7, between horizontal river 9 spacings must satisfy the requirement that the stope upper corner ventilates, one of per 50 meters construction.
Overlap other Main production Systems of work plane that little u type tunnel matches with big U: as schematically shown in Figure 1, 2,
