First, the cause of the coal mine accident caused this accident because carbon monoxide exceeded the standard, which was caused by the burning of large inclined belt in coal mine. After some combustible materials rub the belt, it will cause the belt to burn. Flammable adhesive tape produces a large number of harmful substances such as carbon monoxide and sulfur dioxide after burning, which leads to mine accidents.
There are relevant regulations in the country, that is, the use of this conveyor belt must conform to the specifications, and corresponding early warning devices should be added. But also to cultivate employees' awareness of fire prevention. This coal mine is probably not in place.
Two. Details of the accident The accident happened in an old coal mine built in 1958. The accident caused 17 people to be trapped, of which 16 people died on the spot, and 1 people were being rescued in the hospital. After the accident, the relevant parties immediately organized rescue teams to rescue the fire officers and soldiers in the whole region, and dispatched 18 teams, accounting for 99 * *. Although the police responded quickly, the result of practice is still regrettable. There are too many deaths in this mine disaster.
Third, the common causes of carbon monoxide exceeding the standard There is a lot of carbon monoxide in the coal seam itself, which will be released to the working face when mining, so people engaged in mining basically have serious health problems. When mining, the medium will be broken and some carbon monoxide will be produced. When a large amount of coal is left in the goaf, it will also be oxidized to produce carbon monoxide. In order to prevent this from happening, it is necessary to ensure good ventilation and prepare fireproof materials to prevent oxidation through air.
