SOLUTION OF THE RATIONAL SUPPORTING OF THE GIN-200 IN THE LEAD AND ZINC MINE "RUDNIK" - GORNJI MILANOVAC

The key element in the underground rooms construction is the choice of a support, which due to frequent changes in working conditions can not be universal, and this area is the subject of constant research in mining practice. The mining underground room GIN-200 is the main incline of the new part of the underground mine "Rudnik" and it is made from the surface in the length of 1100 m. According to its purpose it should be functional for a longer period of time. The project solution of support provided the certain methods of supporting according to the working environment, which is presented uniformly. Already in the early phase of this underground room construction, it was determined that these are on interchangeable conditions with cracked and weakened rock mass, and that a certain method of support was chosen, which is applied in practice. This paper presents the solution of the support of the this underground room with a special presentation of specifics and represents a contribution to the mining profession.
