In spite of increasing of working depth in coal mines, the number of accidents and victims have remarkably decreased so far.
However, 1 the accident rate is still high, compared with other industrial sectors, 2 there is no denying that a large scale accident peculiar to deep coal mines, might occur.
On the other hand, in the future, as the working depth will continue to become deeper.
Therefore, proper safety countermeasures for accidents (especially for serious ones such as gas outbursts, rock outbursts and so on) should be established as soon as possible.
