Abstract
The present invention relates to mine ventilation technology field more particularly to a kind of mine ventilation systems and its control method.The mine ventilation system includes blowing shaft, and main breeze fan is equipped in blowing shaft;Several air-supply tunnels, air-supply tunnel are connect with blowing shaft, are equipped with secondary breeze fan in tunnel of blowing;Several return aircourses, return aircourse and air-supply tunnel correspond, and are equipped with secondary return air fan in return aircourse;Further include returnairshaft, main return air fan is installed in returnairshaft.Mine ventilation system design rationally, by improving the aeration structure in tunnel, reduces different return aircourse return air pressure differences by design transition tunnel and fluctuates to returnairshaft bring air quantity.Automated control technology is widely used in coal mine ventilation system by the present invention, so that the ventilation quality of mine ventilation system is improved, convenient for controlling the ventilation condition of entire mine.
Description
(1) technical field
The present invention relates to mine ventilation technology field more particularly to a kind of mine ventilation systems and its control method.
(2) background technique
Mine ventilation system be in the method for force ventilation by ground fresh air directly or after processing, sent by entering the wind roadway
Enter underground work place, foul atmosphere therein is diluted, then is discharged directly or after air-treatment by return air roadway
Into surface air.It is generated in clean air needed for its basic role is to provide people's breathing, dilution and exclusion production process
Pernicious gas and dust remove extra heat and moisture, create the production environment of suitable people's operation.Therefore, reasonable structure
It builds and manages a ventilating system to be not only to create the basis of safety in production and sanitary condition, and be also the various disaster hairs of prevention
Raw important means, to guaranteeing that mine safety production is of great significance.
Mine ventilation system is a complicated kinematic nonlinearity fluid network system, by ground and underground air pressure, temperature and humidity
The influence of numerous internal and external factors such as variation, mining operation progress, roadway deformation, mine ventilation network structure, tunnel windage and well
Lower atmospheric density will change, and then lead to the variation of mine ventilation state, especially mine key place getting working face
Air quantity reduce, may cause the generation of gas accident.It, just must be to mine in order to guarantee that mine ventilation is stable, reliable and effective
The operation of well ventilating system carries out daily maintenance control.
(3) summary of the invention
In order to compensate for the shortcomings of the prior art, the present invention provides a kind of mine ventilation system and its control methods.
The present invention is achieved through the following technical solutions: a kind of mine ventilation system, it is characterised in that: including air-supply
Well is equipped with main breeze fan in blowing shaft;Several air-supply tunnels, air-supply tunnel are connect with blowing shaft, are pacified in tunnel of blowing
Equipped with secondary breeze fan;Several return aircourses, return aircourse and air-supply tunnel correspond, and secondary return is equipped in return aircourse
Wind blower;Further include returnairshaft, main return air fan is installed in returnairshaft.
A kind of mine ventilation system control method, which comprises the following steps:
Step 1: the acquisition control of sensing system completes reception and biography to different instruction and data by wireless sensor
It is defeated;
Step 2: the Partial controll of underground ventilating is completed in ventilating system control by the setting of detecting element;
Step 3: central control system control, the data by acquiring and handling monitoring station generation make tune to the air quantity of ventilation blower
It is whole.
Further, the step 2 is the variation by certain gas concentration or temperature caused by detection mechanical movement
To complete.
The beneficial effects of the present invention are: mine ventilation system design is rationally, by improving the aeration structure in tunnel, pass through
Design transition tunnel reduces different return aircourse return air pressure differences and fluctuates to returnairshaft bring air quantity.The present invention will automate
Control technology is widely used in coal mine ventilation system, so that the ventilation quality of mine ventilation system is improved, it is entire convenient for control
The ventilation condition of mine.

(5) specific embodiment
Invention is further described in detail combined with specific embodiments below.
As shown in Fig. 1, which includes blowing shaft 1, and main breeze fan 2 is equipped in blowing shaft 1;Several air-supplies
Tunnel 3, air-supply tunnel 3 are connect with blowing shaft 1, are equipped with secondary breeze fan 4 in tunnel 3 of blowing;Several return aircourses 5 are returned
Air way road 5 and air-supply tunnel 3 correspond, and are equipped with secondary return air fan 6 in return aircourse 6;It further include returnairshaft 7, returnairshaft 7
Main return air fan 8 is inside installed.
Mine ventilation system control method, comprising the following steps:
Step 1: the acquisition control of sensing system completes reception and biography to different instruction and data by wireless sensor
It is defeated;
Step 2: ventilating system control is completed the Partial controll of underground ventilating by the setting of detecting element, passes through detection machine
Tool runs the variation of caused certain gas concentration or temperature to complete;
Step 3: central control system control, the data by acquiring and handling monitoring station generation make tune to the air quantity of ventilation blower
It is whole.
Embodiment described above, only one kind of the present invention more preferably specific embodiment, those skilled in the art
The usual variations and alternatives that member carries out within the scope of technical solution of the present invention should be all included within the scope of the present invention.
