Wherein: ground monitoring system is mainly made up of industrial computer or existing ground monitoring system.

The monitoring method of a kind of coal and gas prominent monitoring system, feature is: coal and gas prominent monitoring device is respectively It is arranged on digging laneway exit, stope intake porch and exit, return aircourse, the two of tunnel, junctions At individual access adit and have at one and be located at rear, air intake direction, coal and gas prominent Monitor Sub-Station of Less is arranged on and coal and gas prominent prison Survey device wiring recently, and the position of most convenient personal observations.

Wherein: the air pressure monitored in digging laneway exit when coal and gas prominent monitoring device increases 1200Pa Above, and when gas density is more than 3%, regard as there occurs coal and gas prominent accident, when monitoring wind direction and dash direction Time consistent, regard as digging laneway and there occurs coal and gas prominent accident, LCDs instruction refuge taking route；When monitoring wind direction Time in opposite direction with dash, outside regarding as digging laneway, there occurs coal and gas prominent accident, by other coal and gas Prominent monitoring device judges coal and gas prominent place where the accident occurred point, time.

Wherein: the air pressure monitored in stope intake porch when coal and gas prominent monitoring device Increase more than 1200Pa, and gas density is more than 3%, when monitoring wind direction is in opposite direction with dash, assert that stope is sent out Coal and gas prominent accident, LCDs instruction refuge taking route are given birth to；When monitoring wind direction is consistent with dash direction, assert For there occurs coal and gas prominent accident outside stope, other coal and gas prominent monitoring device judge coal and gas Prominent place where the accident occurred point, time,

The air pressure monitored in exit, stope return aircourse when coal and gas prominent monitoring device increases More than 1200Pa, and gas density is more than 3%, when monitoring wind direction is consistent with dash direction, assert that stope there occurs Coal and gas prominent accident, LCDs instruction refuge taking route；When monitoring wind direction is in opposite direction with dash, regard as back There occurs coal and gas prominent accident outside mining face, other coal and gas prominent monitoring device judge coal and gas prominent Place where the accident occurred point, time.

Wherein: when tunnel, junctions is located at the air pressure that air intake side's rearward coal and gas prominent monitoring device monitors Power increases more than 1200Pa, and gas density is more than 3%, when monitoring wind direction is consistent with dash direction, regards as air intake direction Rear there occurs coal and gas prominent accident, LCDs instruction refuge taking route；Monitoring wind direction is in opposite direction with dash Time, regard as front, air intake direction and there occurs coal and gas prominent accident, other coal and gas prominent monitoring device judge coal With gas burst accident scene, time,

When tunnel, junctions is located at the air pressure increasing that the coal and gas prominent monitoring device in front, air intake direction monitors Add more than 1200Pa, and gas density is more than 3%, when monitoring wind direction is in opposite direction with dash, regard as front, air intake direction There occurs coal and gas prominent accident, LCDs instruction refuge taking route；When monitoring wind direction is consistent with dash direction, by Other coal and gas prominent monitoring device judges coal and gas prominent place where the accident occurred point, time,

When tunnel, junctions is located at the air pressure increasing that air intake side's rearward coal and gas prominent monitoring device monitors Adding more than 1200Pa, and gas density is more than 3%, when monitoring wind direction is in opposite direction with dash, meanwhile, tunnel, junctions sets The air pressure monitored in the coal and gas prominent monitoring device in front, air intake direction increases more than 1200Pa, and gas density More than 3%, when monitoring wind direction is consistent with dash direction, regard as being not provided with the tunnel of coal and gas prominent monitoring device There occurs coal and gas prominent accident, other coal and gas prominent monitoring device judge coal and gas prominent place where the accident occurred Point, time, LCDs instruction refuge taking route.

Wherein: when many places monitor coal and gas prominent accident, with the coal and gas prominent monitoring device monitored at first Conclusion is as the criterion.

Wherein: refuge taking route is formulated, it is assumed that a monitoring place there occurs coal and gas prominent accident, dashes forward with gas according to coal Go out monitoring device, coal and gas prominent Monitor Sub-Station of Less arranges position, mine laneway route map, makes each coal in advance and dashes forward with gas Go out the refuge taking route figure that Monitor Sub-Station of Less is corresponding, principle according to this, each coal and gas prominent is made in all monitoring places in advance The refuge taking route figure that Monitor Sub-Station of Less is corresponding, called, ground simultaneously when one monitoring place there occurs coal and gas prominent accident Monitoring system shows same information, for instructing formulation to sue and labour measure in time.

Wherein: refuge taking route is formulated, when the gas density that coal and gas prominent monitoring device monitors is more than 3%, at coal Showing this some flicker in mine laneway figure with the LCDs of Gas Outburst Monitor Sub-Station of Less, personnel withdraw and judge also according to this figure Determining route, ground monitoring system shows same information simultaneously, for instructing formulation to sue and labour measure in time, this point refer to coal with watt A bit in this prominent monitoring device P1, P2, P3, P4, P5, P6, P7, P8.

One of the above coal and gas prominent monitoring system monitoring method, coal and gas prominent when and where is determined by Computer programming realizes, accordingly, after coal and gas prominent accident occurs, in ground monitoring system display alarm, according to actual feelings Condition determines and implements the concrete measure of accident treatment.As: involve scope removes people, power-off etc..

The beneficial effects of the present invention is provide one can monitor in real time coal and gas prominent occur time air pressure, watt This concentration, the coal and gas prominent monitoring system of wind direction index, automatic alarm, can determine whether when coal and gas prominent accident occurs Between, place, Intensity of coal-gas burst can be qualitatively judged out accordingly, in conjunction with a kind of coal and gas prominent monitoring system monitoring side Method, promptly and accurately judges coal and gas prominent traffic injury time, place, and graphical prominent accident involves scope, determines down-hole Human evacuation route, determines and implements the concrete measure of accident treatment in time, such as power-off, removes people etc., it is to avoid coal and gas prominent Possible coal and gas explosion after accident generation, the loss making accident cause is down to minimum.
