Abstract
The invention discloses a coal mine ventilation system. The coal mine ventilation system comprises a main air return channel and multi-air-inlet and multi-air-return equipment, wherein the multi-air-inlet and multi-air-return equipment is communicated with the main air return channel and formed by a plurality of auxiliary air return channels. The main air return channel is formed in the top of a coal mine main roadway and connected with a blowdown stack, the auxiliary air return channels are formed in the tops of branch roadways on the two sides of a coal mine coal face, draught fans are arranged at the joints of the auxiliary air return channels and the main air return channel, and suction fans are arranged at air inlets of the auxiliary air return channels. According to the coal mine ventilation system, the ventilation distance of the coal face is shortened, the content of fresh air in the coal face is greatly increased, air quality in the roadways is similar to air quality outside a mine, and therefore it is avoided that good health of workers is damaged and various potential safety hazards are caused due to poor ventilation, and the accident rate of the coal mine is effectively controlled.
Description
Technical field
The invention belongs to mine equipment technical field, be specifically related to a kind of coal mine ventilation system.
Background technology
Mine ventilation is that ground fresh air is continuously sent to Ge Yongfeng place, down-hole (as getting working face), its objective is dilution and gets rid of pernicious gas and mine dust, and personnel in the pit is provided required oxygen, creates good weather conditions simultaneously.Mine ventilation is to ensure one of topmost technological means of mine safety.< < safety regulations in coal mine > > regulation: mine must adopt mechanical ventilation; Must be equipped with the main ventilation fan of two same models, an operation, one is standby; Mine must have complete independently ventilation system, must appraise and decide mine output by actual air volume, i.e. " with wind fixed output quota ".
Can whether mine ventilation system be reasonable, to the quality of whole mine ventilation situation and ensure that mine safety production plays an important role, should, guaranteeing, under the prerequisite of safety in production, to reduce ventilation expense, make every effort to economical rationality simultaneously.
It is to using production tunnel as air intake passage that existing underground coal mine mine ventilation equipment all adopts mechanical forced ventilation equipment, and the shortcoming of this mechanical forced ventilation equipment is more.
Summary of the invention
Technical problem to be solved by this invention is: a kind of efficient, energy-conservation, safe coal mine ventilation system is provided.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of coal mine ventilation system, comprise many many return air of air intake equipment that return air main passage and a plurality of return air subchannels that communicate with return air main passage form, return air main passage is arranged on the top in coal master tunnel, described return air main passage is connected with blowdown stack, described return air subchannel is arranged on a top, tunnel of stope both sides, colliery, blower fan is arranged on the junction of described return air subchannel and return air main passage, and the air intake place of described return air subchannel is provided with suction fan.
On the basis of technique scheme, above-mentioned return air subchannel consists of with the duct set that is connected return air branched bottom many return air branched bottoms of different length, the valve being arranged in return air branched bottom.
As improvement of the present invention, on above-mentioned return air subchannel, ventilation controller is set.
The valve that above-mentioned ventilation controller is matched by the He Yugai inlet scoop, inlet scoop of side that is arranged on the body of described return air subchannel is formed.
Above-mentioned valve is electrically operated valve.
Compared with prior art, the beneficial effect that the present invention has is:
The present invention is reasonable in design, shortened the ventilation distance of coal face, fresh air content in coal face increases substantially, thoroughly solved near air quality problems face in tunnel, air quality in tunnel and the air quality outside mine are close, thereby avoided the healthy and various potential safety hazards of the harm workman that causes due to improper ventilation, effectively controlled coal mining accident rate.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of coal mine ventilation system of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
As shown in Figure 1, a kind of coal mine ventilation system, many many return air of air intake equipment that a plurality of return air subchannels 4 that comprise return air main passage 1 and communicate with return air main passage 1 form, it is characterized in that: return air main passage 1 is arranged on the top in coal master tunnel 3, described return air main passage 1 is connected with blowdown stack, described return air subchannel 4 is arranged on a top, tunnel of colliery stope 6 both sides, blower fan 2 is arranged on the junction of described return air subchannel 4 and return air main passage 1, and air intake 5 places of described return air subchannel 4 are provided with suction fan.
The present invention is reasonable in design, shortened the ventilation distance of coal face, fresh air content in coal face increases substantially, thoroughly solved near air quality problems face in tunnel, air quality in tunnel and the air quality outside mine are close, thereby avoided the healthy and various potential safety hazards of the harm workman that causes due to improper ventilation, effectively controlled coal mining accident rate.
Those of ordinary skill in the art will be appreciated that, above embodiment is only for the present invention is described, and be not used as limitation of the invention, as long as within the scope of connotation of the present invention, to the variation of the above embodiment, modification, all will drop within the scope of claim of the present invention.
