Abstract

A system and a method for active fire extinguishing and explosion suppression in coal mine workplaces are especially suitable for monitoring, early warning, and actively inserting and inhibiting in spaces that are prone to fire and explosion hazards, and the spaces comprise coal mine workplaces that generate gas and coal dust, and gas and coal dust accumulated areas in coal storage bunkers, and the like. Quantitative evaluation of environmental space explosion hazard degrees is obtained by the system through active monitoring and comprehensive evaluating of a plurality of parameters such as gas composition, dust concentrations, ambient temperature, photoelectric signals, etc. in a working environment, thereby providing theory criteria for action execution of explosion suppression mechanisms. According to the invention, real-time monitoring of environmental parameters of gas and coal dust in workplaces and advanced quantitative determination of explosion hazard degrees are realized, and therefore effective explosion suppression measures are adopted proactively before an explosion hazard occurs, and the probability of successful execution of explosion suppression is increased.

Description

technical field [0001] The invention relates to an active fire extinguishing and explosion suppression system and method for coal mine workplaces, especially suitable for the monitoring, evaluation and active inerting explosion suppression of explosion hazards in coal mining, processing workplaces, coal storage bins and other spaces containing gas and coal dust . Background technique [0002] The operation process of underground coal mines, especially the tunneling working face, coal mining working face and gas drainage drilling construction in coal mines are mostly accompanied by the release of gas and the generation of a large amount of coal dust. In underground coal bunkers and coal processing The upper space of the coal bunker in the site is also often a space where gas and coal dust gather together. When the mixture of gas and coal dust reaches a certain concentration, if there is an ignition source, it is very easy to cause the explosion of the mixture of gas and coal...
