... formulae are given for determining the permissive width of path, the period of starting the longwalls and criteria of provoking caving of suspending roofs. The necessary load bearing capacity of supports has been established according to the roof class and the height of workings as well as criterion...

... conditions closed profile supports should be used with growing load bearing capacity at a limited or controlled yieldability. Moreover, some analytical methods of computation of fundamental parameters of rock pressure and supports have been discussed taking into account the condition of dynamic rock...
