Specific embodiment
In order that those skilled in the art more fully understand the technical scheme in the application, below in conjunction with the application reality
The accompanying drawing in example is applied, the technical scheme in the embodiment of the present application is clearly and completely described, it is clear that described enforcement
Example is only some embodiments of the present application, rather than the embodiment of whole.Based on the embodiment in the application, this area is common
The every other embodiment that technical staff is obtained under the premise of creative work is not made, should all belong to the application protection
Scope.
Embodiment one
Please be as shown in figure 1, the present embodiment provides a kind of mine safety system, including for presetting under real-time monitoring mine
Position dust concentration, and the dust arrester 100 of dedusting is carried out when the predeterminated position dust concentration is more than preset concentration;For
The positioner 200 of location of personnel under real-time monitoring mine;Predeterminated position temperature and gas are dense under real-time detection mine
Degree, and the prior-warning device 300 blown when the predeterminated position temperature or gas density are more than preset value;Respectively with it is described
Dust arrester 100, the positioner 200 and the prior-warning device 300 connect, when the predeterminated position dust is dense under mine
When degree, temperature or gas density are more than preset value, for notifying the communicator 400 of staff.
Under mine especially under coal mine, in the recovery process in colliery, danger of the dust concentration under mine to human body
Evil is larger, and when dust concentration reaches to a certain degree, may set off an explosion, so as to cause serious accident.Therefore, to ore deposit
The monitoring and process of downhole powder dust concentration is very necessary.There is real-time monitoring dust in prior art and process dust, detection temperature
With the system and device of gas density, can the concentration of dust, temperature and gas density under monitoring mine in time, and can be to adopting
The information for collecting is processed, however, due to dust, temperature and gas monitoring and process with the degree of association of staff not
Height, still results in the healthy of staff in ore deposit underground work and is endangered by dust, personal safety by gas explosion and
Dust is threatened naturally.
Mine safety system provided in an embodiment of the present invention, being capable of predeterminated position powder under real-time monitoring mine due to including
Dust concentration, and the dust arrester 100 of dedusting is carried out when predeterminated position dust concentration is more than preset concentration, further comprises for right
Location of personnel carries out the positioner 200 of real-time positioning under mine, also includes when the predeterminated position temperature or gas are dense
Degree more than the prior-warning device 300 blown during preset value further comprises respectively with the dust arrester 100, the positioner
200 and the prior-warning device 300 connect, when under mine the predeterminated position dust concentration, temperature or gas density more than pre-
If during value, for notifying the communicator 400 of staff, because dust arrester 100, prior-warning device 300 are to ore deposit downhole powder dust
Carry out in real time when concentration, temperature, the monitoring of gas density, therefore, when dust concentration, temperature, gas density are more than under mine
During preset value, dust arrester 100 can in time carry out dust removal process, it is ensured that under preset concentration, early warning is filled dust concentration
Putting 300 can be hybrid in time, and divulging information, it is fresh distinguished and admirable to send, wherein, default dust concentration is do not have to the healthy of staff
Less concentration is had an impact or affects, to cause the natural temperature of dust, default gas density is to draw to preset temperature
The concentration below the limting concentration of gas explosion is played, when predeterminated position dust concentration is more than preset concentration under mine, or temperature
When value and gas density are higher than preset value, communicator 400 can notify in time in the predeterminated position or near this to preset
Position will go the staff of predeterminated position so that staff can be prevented effectively from time away from the predeterminated position
Dust concentration is too high, the harm caused by dust nature or gas explosion to staff.
Embodiment two
