Since the beginning of this year, the Shanxi Bureau of the State Mine Safety Supervision Bureau has strictly investigated the accident, strictly investigated the responsibility of the relevant responsible persons, resolutely punished illegal acts, and made every effort to prevent and curb mine production safety accidents.
It is understood that up to now, the Shanxi Bureau of the State Mine Safety Supervision Bureau has approved and closed a total of 87 coal mine accidents this year, 2,169 people have been held accountable in accordance with the law, 182 people have been removed or dismissed (including 46 mine managers), 35 people have been transferred to judicial organs (including 3 mine directors), and "joint punishment" has been carried out against 2 coal mines and 2 main persons in charge of coal mines.
Accidents involving danger in larger coal mines shall be investigated and dealt with in accordance with the accidents. In 2023, a total of 78 people will be held accountable for 5 risk-related accidents in Panchengling, Ermugou, Maidizhang, Xiaohuigou, and Shaping, of which 12 people will be held accountable by the coal industry group.
With "zero tolerance", we will seriously investigate and deal with accidents that are concealed, falsely reported, and delayed. In the "big doxxing" work to crack down on the concealment of accidents, a total of 1,500 people were held accountable in accordance with the law, 119 people were removed or dismissed from their posts (including 28 mine managers), and 32 people were transferred to judicial organs (including 2 mine directors).
Establish a working mechanism for accident warnings and interviews. For each accident, a three-dimensional animation and warning education film are produced to analyze the causes, which are distributed free of charge to regulatory departments at all levels and mining enterprises, and do a good job in releasing warning information about typical accidents, and urge all mines to be truly vigilant and prevent accidents. Conduct hierarchical interviews with cities and counties where mine production safety accidents occur, consolidate the responsibilities of the main person in charge, the person in charge and the main person in charge of the mine safety supervision department, and promote the fundamental solution of the problem in all localities.
Typical cases of accidents that have been closed recently are as follows:
