Another accident, same cause

An initial investigation has found that the coal mine accident in Wangjialing, Shanxi province, in which 153 workers were trapped, was caused by an accidental rush of water that tore through the mine. But the public can no longer tolerate these accidents, says an article in Beijing News. Excerpts:

Reflecting on past coal mine accidents, we see accidental factors were to blame for most of them. Even the Wangjialing accident was caused by the accidental digging through the aquifer.
