【 摘 要 】

The damping of inefficient mines caused the closure of 4 underground coal mines in the Ostrava-Karviná basin. A time span between the beginning of damping and mining activity finishing can be very short or, on the other hand, relatively long. There are positive and negative consequences in economic and social field in both cases. The contribution analyses the way of damping of these closed underground coal mines on the basis of statistical information.
