Example Embodiment

[0028] The present invention will be further described below in conjunction with the drawings and embodiments: figure 1 It is a schematic diagram of the principle of the coal mining face of the present invention, figure 2 It is a schematic diagram of the principle of the tunneling face of the present invention.

[0029] Such as figure 1 , 2 As shown, the gas outburst recognition method based on safety monitoring system data in this embodiment includes

[0030] a. Collect gas concentration and wind speed and direction data on the working face through gas sensor and wind speed and direction sensor;

[0031] b. Determine the gas outburst based on the gas concentration and wind speed and direction data at different positions on the working face.

[0032] In this embodiment, the prominent alarm can be realized according to the position, type and data change law of the existing sensors installed on the working surface, which simplifies the judgment process, and can realize the gas outburst...

Abstract

The invention provides a method for recognizing gas outburst based on data of a safety monitoring system. The method comprises the steps of a, acquiring gas concentration and wind speed and direction data of a working face through gas sensors and wind speed and direction sensors; and b, judging gas outburst according to the gas concentration and wind speed and direction data at different positions of the working face. According to the invention, judgment for gas outburst can be realized through utilizing the existing installed sensors of the working face, so that damages brought about by gas abnormity in safety production are avoided, an alarm is given for gas outburst through the change regularity in position, type and data of the sensors installed at the working face, and the overall emission rate of gas outburst is calculated. The judgment process is simple, judgment for gas outburst is realized without increasing equipment, and the cost is saved.

Description

technical field [0001] The invention relates to the field of coal mine safety, in particular to a gas outburst identification method based on safety monitoring system data. Background technique [0002] Coal mine is a very important energy source. It is generally divided into underground coal mines and open-pit coal mines. The vast majority of coal mines in my country belong to underground coal mines. Over the past few years, with the development of my country's coal mining industry, many problems have been brought about while improving economic growth, among which safety issues have attracted more and more attention. Coal mine safety has always been a top priority. Gas outburst refers to that with the increase of coal mine mining depth and the increase of gas content, the weak coal seam breaks through the resistance line under the action of in-situ stress and the gravitational force of gas release in the coal seam, causing a large amount of gas and coal to be released inst...
