ROCKBOLTS SUPPORT OF THE DRIFTS AND CROSSCUTS IN BAUXITE

Sažetak

The article discusses the excavation method in bauxite underground exploitation of the »Trobukva« mine in the »Bauxite Mine Posušje«, and the experiences in drift and crosscut supporting so far. Frame support is the only activity which is not mechanized and it has an important part in the production costs. Therefore the possibility of supporting by bolts and wire mesh has been developed. The estimation of bolting elements was performed for the Swellex boit and it proved, that bolt support compared with the frame support, beside the technical and safety advantages has also a considerable economic justification.
