The implementation of modified pillar method in the excavation field 2 (OP-2) in the 'Osojno-jug' RL 'Lubnica' Mine
Primena modifikovane stubne metode u otkopnom polju 2 (OP-2) u jami 'Osojno-jug' RL 'Lubnica'
According to the present geologic conditions, designing the modified pillar method of excavation with felling roof coaland collapsing the roof is mandatory and that is one of the goals of this method. Considering the planned growth in production in OP-2, the need for the modification of present coal exploitation in the deposit of the 'Lubnica' pit is imposed. The fact that the present method of coal excavation marks more than 40% loss of balance reserves, which is unacceptable amount of excavation loss, is the main reason for changing the excavation method.
