风流短路法在输送带火灾远程救援系统的应用

Application of Air Flow Short Circuit Method to Remote Rescue System of Conveyor Belt Fire Disaster

为了有效降低输送带火灾所造成的伤亡程度,对龙东煤矿西翼采区进行了试验研究,设计了一套基于风流短路法的输送带火灾远程应急救援系统,该系统在采区分别布置6道电控气动的自动救灾门,根据井下火灾的具体情况,通过光纤环网,远程控制救灾门的开闭,灵活改变风流的方向,将有毒烟流直接导入回风巷,同时遏制灾情向工作面的扩散,达到控灾救人的目的;而在正常时期,救灾门承担过车的任务,实现自动闭锁功能。

In order to effectively reduce the casualties degree of the conveyor belt fire disaster occurred in the mine,an experimental study was conducted in the West Wing Mining Block of the Longdong Mine.A remote emergency rescue system of the conveyor belt fire disaster was designed based on the air flow short circuit method.The system had several electric control pneumatic automatic rescue doors individually set up in the mining block.According to the certain conditions of the fire disaster occurred in the underground mine,with the optical fiber looped network,the open and close of the remote control rescue door and the air flow direction flexibly changed,the poisoned smoke flow could be guided to the air return gateway.Meanwhile the disaster expansion to the coal mining face should be controlled in order to have the target to control the disaster and rescue the miners.In the normal period,the rescue door would let the vehicles passing through and have the automatic interlock function.
