Abstract
The invention provides a stope face parallel dual-U-type roadway, and aims to solve the problems that since stope face roadway arrangement is unreasonable, upper corner gas is difficult to control, control is uncompleted, and multiple roadway arrangement stope efficiency is low. The stope face parallel dual-U-type roadway comprises a track roadway, an equipment roadway, an air return roadway, an auxiliary air return roadway and an auxiliary air inlet roadway. The track roadway and the equipment roadway are located above a stope face, the air return roadway, the auxiliary air return roadway and the auxiliary air inlet roadway are located below the stope face, the right ends of the track roadway, the equipment roadway and the air return roadway are provided with an open-off cut roadway communicated with the track roadway, the equipment roadway and the air return roadway, the right ends of the auxiliary air return roadway and the auxiliary air inlet roadway are communicated, a plurality of ventilate connected roadways are arranged between the auxiliary air return roadway and the auxiliary air inlet roadway at intervals, and gas drainage pipes communicated with a goaf. The stope face parallel dual-U-type roadway has the advantages of green energy, conservation of resources and effective increase of recovery rate.
Description
Technical field
The present invention relates to support in gateway of coal mining face arrangement under coal mine, be specially a kind of stope double-U-shaped tunnel arranged side by side.
Background technology
In China's coal-mine down-hole coal excavation process, generally adopt longwell process for stoping at present, stope according to entering, return aircourse arrangement is different, can be divided into " U " type, " U+L " type, " three enter two go back tos " etc., but there is the drawback that is difficult to overcome in these tunnel arrangements self at present, be when stope back production, upper corner gas control difficulty is large, improvement is not thorough; Shi Duo lane is arranged, coal column is set many, has reduced the rate of extraction.
Summary of the invention
The present invention for solve existing support in gateway of coal mining face arrange unreasonable cause upper corner gas control difficulty large, administer thoroughly and the low problem of the rate of extraction is arranged in many lanes, provide a kind of stope double-U-shaped tunnel arranged side by side.
The present invention adopts following technical scheme to realize: stope double-U-shaped tunnel arranged side by side, comprises the track lane, equipment lane, return airway, auxiliary return airway, the auxiliary air intake lane that set gradually from top to bottom; Track lane and equipment lane are positioned at the top of stope, return airway, auxiliary return airway and auxiliary air intake lane are positioned at the below of stope, the right-hand member of track lane, equipment lane and return airway is provided with and is communicated with Qie Yan lane with three, the right-hand member in auxiliary return airway and auxiliary air intake lane is communicated with, and between auxiliary return airway and auxiliary air intake lane, be arranged at intervals with some air connections, in auxiliary return airway, be provided with the gas drainage pipe being communicated with goaf.
After coal mine down-hole tunnel has been arranged, carry out back production, stoping period, the equipment lane of work plane inlet side and track lane coal column can carry out back production, simultaneously along with the advance of the face, equipment lane, track lane, working face open-off cut eye and return airway are caving thereupon, and auxiliary air intake lane and auxiliary return airway can successfully remain, and are this work plane and Adjacent Working Face service; Equipment lane, track lane, auxiliary air intake lane are three air intake lanes, and air intake is flowed through after work plane, and a part of distinguished and admirable inflow return airway flows into auxiliary return airway by air connection after the distinguished and admirable upper corner of flowing through of a part, has solved upper corner gas exceeding limit problem; And form whole wind pressure ventilation system after setting up auxiliary air intake lane, and with fresh wind circulation, cross the high concentration gas of the auxiliary return airway of air connection dilution, guaranteed that the gas density of auxiliary return airway does not exceed standard; Gas drainage pipe can be to the goaf at shutoff air connection place by high negative pressure pump drainage simultaneously, force goaf gas to discharge mine through gas pipeline, overcome existing support in gateway of coal mining face arrange unreasonable cause upper corner gas control difficulty large, administer not thorough and many lanes and arrange the low problem of the rate of extraction.
Reasonable in design of the present invention is reliable, has guaranteed that the gas density of return airway is no more than 1.0%, has strengthened the air quantity of work plane, and wind gas-removing ability effectively improves; And make goaf gas discharge mine by releasing pipe, improve stope extracting result; Between equipment lane and track lane, coal column can carry out back production simultaneously, has reduced goaf drop coal column, has advantages of environmental protection and energy saving, economizes on resources and effectively improves the rate of extraction.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1-track lane, 2-equipment lane, 3-return airway, 4-assists return airway, ，6-Qie Yan lane, the auxiliary air intake lane of 5-, 7-air connection.
The specific embodiment
Stope double-U-shaped tunnel arranged side by side, comprises the track lane 1, equipment lane 2, return airway 3, auxiliary return airway 4, the auxiliary air intake lane 5 that set gradually from top to bottom; Track lane 1 and equipment lane 2 are positioned at the top of stope, return airway 3, auxiliary return airway 4 and auxiliary air intake lane 5 are positioned at the below of stope, the right-hand member of track lane 1, equipment lane 2 and return airway 3 is provided with and is communicated with Qie Yan lane 6 with three, the right-hand member in auxiliary return airway 4 and auxiliary air intake lane 5 is communicated with, and between auxiliary return airway 4 and auxiliary air intake lane 5, be arranged at intervals with some air connections 7, in auxiliary return airway 4, be provided with the gas drainage pipe being communicated with goaf.
In specific implementation process, by track lane 1, equipment lane 2 and return airway 3, form first U-shaped tunnel, by auxiliary return airway 4 and auxiliary air intake lane 5, form second U-shaped tunnel, between 1 two the air intake lanes in equipment lane 2 and track lane, at interval of one of 300m construction, get in touch with horizontal river, between return airway 3 and auxiliary return airway 4, at interval of an air connection 7 of 50-70m construction, meet the requirement of upper corner gas control; Auxiliary air intake lane 5 has a horizontal river of contact to carry out whole wind pressure ventilation, the gas density that dilution ventilation connection roadway 7 blows out with auxiliary return airway 4 in the construction of right side, tunnel.
