Prototype of temporary mechanized mine roadway support of the dog headings
Technology of the dog heading driving with use of roadheaders or explosive material has been described In the pre-
sent study. Difficulties occurring during dog heading driving, particularly those related with the support installing, have
been presented. Constructional solutions of different mechanized mine roadway supports, including their advantages
and disadvantages, have been presented. Based on the executed analysis of the mine dog heading driving, including
construction of mechanized roadway supports, a new concept of temporary mechanized roadway support has been
developed and its technical parameters have been cited.

Tail gatedeformation characteristic during plow exploitation of the 1/VI longwall
face in 385/2 seam in LW “Bogdanka” mine
The article presents the results of dislocations and deformations measurements of the tail gate obtained during the first
plow complex exploitation in Lublin Coal “Bogdanka” mine. Together with the advance of the longwall face the tail gate
was maintained for use in future exploitation. For particular types of roof support and rockmass reinforcement methods
(cribs, rod bolts and string bolts) the values of heading convergence, fracture zone reach and fissures have been defi-
ned, indicating the rock mass strengthening effect depending on the chosen technical solution.
