掘进安全技术装备系列化,汇集多种安全技术装备为一体,防范与综合治理瓦斯煤尘相结合,层层设防,多环节把关,确保局扇供电方式可靠,安全运转,连续供给新鲜风流稀释瓦斯,从根本上防止瓦斯聚积。同时改变检测瓦斯浓度方式,由间断检测变为连续检测,可以随时了解某一地点瓦斯浓度,及时发现问题,当瓦斯浓度超限,可立即断电、报警,工作人员迅速撤离现场。还采取多种手段,洒水喷雾除尘,净化空气,减少煤尘飞扬,并设法消除电气设备失爆和不完全爆破所造成的各种类型引爆火源,从而达到控制瓦斯煤尘事故的目的。
Tunneling safety technology and equipment series, a collection of a variety of safety technology and equipment as a whole, prevention and comprehensive management of gas coal dust combination of layers fortification, multiple links checks to ensure that Fan power supply reliable and safe operation of continuous supply of fresh air dilute gas , Fundamentally prevent gas accumulation. At the same time change the way to detect gas concentration, continuous detection from intermittent detection, you can keep abreast of gas concentrations in a certain location, and timely detection of problems, when the gas concentration exceeds the limit, you can immediately power down, alarm, staff promptly evacuated from the scene. Also take a variety of means, water spray dust, purify the air and reduce dust flying, and try to eliminate electrical equipment explosion and incomplete blasting caused by various types of detonating fire, so as to achieve the purpose of controlling gas coal dust accident.
