Ladies and Gentlemen, I want to welcome you on behalf of the Government of Montenegro and to share the pleasure with you that today – on the Miners' Day and the 68th anniversary of the founding of Bauxite Mines Nikšić – after 10 years we are renewing the exploitation of red bauxite in mining "Biočki stan".
The engineering layout of the underground mining of bauxite by the room-pillar method is shown in Figure 2. The method has a length of 80-150m and a width of 40-60m. The blasting method is used to break the mine. It is not supported or supported by bolts. When the stability of the roof is poor, a ceiling of 0.5~1m should be reserved.

Methods of Bauxite Mining. There are two main methods for mining bauxite – open-pit mining and underground mining. Open-pit mining involves digging a massive pit in the ground and removing the layers of bauxite ore using heavy machinery. On the other hand, underground mining involves tunneling deep into the earth to access bauxite deposits.
