? Chongqing coal mine accident killed 16 people, this accident is man-made or accidental?
Chongqing Energy Investment Yu new energy company under the Songzao coal mine carbon monoxide overrun accident, *** caused 17 people trapped. Up to now, 17 trapped people have been searched and rescued, of which 16 people have no vital signs, 1 person has been sent to the hospital for full rescue.

After the accident, Chongqing Municipality, Qijiang District, the two levels of the emergency response plan, the establishment of rescue and rescue, medical rescue, aftermath, investigation and evaluation of the working group, emergency response, medical care, public security, firefighting and other departments at the scene to carry out rescue and disposal work.
16 vivid life, so forever left the world. These 16 victims, most of them are the backbone of the family, in order to a family they work tirelessly, not afraid of dirt. But now, an accident so that they will never have a tomorrow, which means that 16 families lost dependence and loved ones, really think about it all feel incomparable grief.
In front of the incident mine, from a number of mine rescue team personnel assembled in the open space, a team of rescue personnel ascending the well, another team of rescue personnel immediately carrying rescue equipment down the well. Chongqing can cast Yu new energy company related person in charge told reporters, *** there are 18 rescue teams involved in rescue. The accident occurred far from the wellhead, the well temperature is high, toxic and harmful gases gathered has not yet dissipated, coupled with their own rescue equipment to carry a heavier, to the rescue caused greater difficulties.
The former State Administration of Safety said in response to the accident report that the accident revealed the main problems: First, the site safety management is weak. The maintenance personnel did not carry out regular maintenance on the belt conveyor and replace the rollers according to the regulations, causing the belt to run off and spill the goods seriously. Secondly, the management of safety hazards is not in place. After the beltway appeared bottom drum, slice gang and other problems, did not repair in time, to the safety of production has brought hidden dangers.

The Points for Emergency Response and Rescue Work in Mine Fire Accidents, which was released on Sept. 14 on the official website of the Ministry of Emergency Management, pointed out that fires of external causes in mines are caused by open flames, electric sparks, mechanical friction, blasting, and other external heat sources, and mainly occur in locations such as the mining face, the shaft, the underground yard, the beltway, the electromechanical refuge, and other roadways with electromechanical equipment. The main threat of mine fires to people in danger is the high temperatures and flames caused by burning, and the production of large quantities of carbon monoxide and other toxic gases caused by the poisoning of people in danger.
According to the Chongqing Qijiang District Emergency Management Bureau, the incident was caused by a belt fire on the transportation equipment, which led to the accident, and why the fire suddenly broke out has yet to be investigated. In other words, from the initial cause, this may be another accident caused by security management loopholes.
In the production operation of coal mines, the beltway is an important auxiliary transportation equipment, due to the belt fire triggered by the safety accidents, this is not the first case. For example, in 2015, a similar accident occurred in the Xinghua coal mine in Heilongjiang province, killing 21 people and leaving one person unaccounted for, a case that was publicly notified by the former State Administration of Safety Supervision for a warning effect.
So, there have been warnings and lessons learned in the first place, why repeat the mistakes again? Behind the belt fire, there is no regular maintenance and inspection? The daily safety production mechanism, why did not detect the risk in time?
It is worth noting that the Songzao coal mine, one of the five largest state-owned coal mines in Chongqing, is also the largest coal mine in the region. This means that its production scale is quite large, in terms of production safety and security, should also have a relatively small and medium-sized coal mines more standardized and regulated control processes. After all, if an accident occurs, the cost could be quite heavy.
In the field of safety, there is a classic "Hein's Law", that is, behind every serious accident, there are often 300 attempted precursors, as well as 1,000 hidden accidents. This time, the accident has once again confirmed it.

In fact, just three months ago in June, the local Coal Mine Safety Supervision Bureau had carried out a special inspection of the coal mine to identify and manage major hazards, and directly found nine hidden safety problems. Visible due to the production safety mechanism, and did not fall into place, to some extent, this risk loophole, for the subsequent accidents buried an important ambush.
