Improper brakes on bus led to crash at mine in Inner Mongolia that killed 22

A mine in the Inner Mongolia autonomous region illegally refitted a bus to transport workers, which led to a severe accident last week, according to a statement issued by the Office of the Work Safety Committee of the State Council on Wednesday.

A shuttle bus carrying miners to work crashed into the side of the underground tunnel after a brake failure, killing 22 and injuring 28 in a mine of Yinman Mining Co in Xiliin Gol League.

Investigators found that Yinman Mining Co violated regulations and used an illegally modified bus to carry 50 miners, even though it had a rated capacity of 30 passengers, according to the statement.
