摘要：
In the paper, after short historical outline, a development of roof bolting use in Polish coal mines on the span of last twenty years was presented. Two characteristic examples of use were given. First of them is related to the solution, which found the widest use in mines. It consists in replacement of abutment at longwall and entry crossing with bolts. Second example concerns the use of independent roof bolting. For both examples, the geological conditions were described, as well as the applied patterns of bolting and the principles of support and mine working stability control.
