Use of the system of dual-use of gateroads represents a significant change in the
hitherto preferred method of addressing of mining works development. The entire system is
based on the principle of reuse of one gateroad during the process of mining of the pair of
neighbouring mining panels. The basic condition for its possible application is the stability of
the supporting reinforcement of the gateroad so as for it to be able to withstand the additional
loads originating in conducting longwalls or other expected supplementary loads to ensure the
stability of the mine working throughout its required service life. Sufficient stability of these
workings is ensured by the high anchoring method. It is a supporting system of long, large-area,
possibly atypical mine workings, in which the elements of supporting reinforcement are
embedded in solid layers of higher overburden of the supported mine working. The following
paper presents the hitherto results of the process of verification of suitability of deployment of
the high anchoring method for the aforementioned purpose, which was carried out in situ in
the gateroad 063 5348 of Paskov Mine.
