65438+ 10 month 1 1 Jixi mine disaster

The cause of Fengjie "10 17" mine accident was identified as coal mine gas explosion. The death toll has risen to nine and four people are still missing. It seems that the effective detection and protection of gas has become a key issue in the accident, and it is still a link that needs long-term strict control. In my opinion, the cause of Fengjie mine disaster is firstly gas explosion, and secondly it should be attributed to poor ventilation, because even poor ventilation will definitely trigger various gas alarms, but the deepest reason is that the ignition source cannot be effectively controlled during coal mining blasting, otherwise the concentration of gas and other gases will not be detonated. At present, blasting equipment is traditional and aging. A considerable number of coal mine blasting equipment are still mainly primitive and simple blasting devices. There is no strict three-person chain, no good blasting detection measures and accurate detection means, and the operation is arbitrary. I think if we consider from this link, it may be that the coal miners did not extend the blasting cable without authorization, which led to many exposed connectors being placed at will, which made the contact resistance of the blasting circuit too large, and the fire was struck at the connectors when shooting, which is estimated to be the direct result of this gas explosion. Life is life, don't make up for it every time something happens, it's too late to regret it! Call on safety supervision departments at all levels and coal mine production units to ensure the imported technology of coal mine products for the purpose of safe production. For example, using the existing advanced intelligent blasting equipment to complete the detection of various related parameters and conditions can effectively avoid the above-mentioned human misoperation.
