Selective limestone mining without drilling or blasting.

Surface miningin Russia

A member of the Eurocement Group, the mine ZAO Kavkazcement is located near the Black Sea in Russia and is one of the largest cement producers in the Northern Caucasus. In the selective mining of limestone, WIRTGEN surface miners guarantee constantly highly daily rates without drilling or blasting.

Since 2005, operations at ZAO Kavkazcement have relied on mechanical mining using the surface mining method. The mining performance of the two 2200 SM – the small-est surface miners from the broad WIRTGEN product range – that were initially ordered impressed Eurocement so much that, in 2008, the next larger size was ordered – the 2500 SM. Decisive for Eurocement was that the sur-face miners should deliver the required mining tonnage with high productivity and at low operating costs, that the material should be reliably crushed within the prescribed gradation, and that the miners should suit the existing mine structures optimally. Three 2500 SM are currently operating in the mine.

Excellent experience with WIRTGEN surface mining

VARIOUS DIFFERENT LOADING OPTIONSOne of the main advantages of surface mining over drilling and blasting is that the limestone can be loaded directly onto trucks by means of a powerful transfer system. Eurocement makes use of further loading methods, however. If, for example, material is required for a temporary embankment stabilization, the surface miners discharge the cut limestone sideways onto a pile. One benefit here is that the cutting pro-cess is always entirely independent from the truck loading. A further possibility for material loading is to deposit the limestone as a wind-row behind the surface miner without the use of the loading conveyor.

ENVIRONMENTALLY FRIENDLY SURFACE MININGWith WIRTGEN know-how from highly devel-oped cutting technology, limestone is mined at ZAO Kavkazcement in a highly environmentally friendly manner without drilling or blasting.

1 | After the successful use of two WIRTGEN 2200 SM, three WIRTGEN 2500 SM were purchased to extend capacity.

2 | WIRTGEN surface mining leaves precise and stable slopes behind as well as flat, easily maneuverable areas.

3 | In the mine the WIRTGEN 2500 SM cuts limestone with a working width of 2,5 meters and a working depth of between 450 and 500 mm millimeters.

«The use of surface miners takes a huge strain off the environment – while increas-ing safety in the mine at the same time.» Viktor Gustov, Mining Director, Eurocement
