Titan Cementara Kosjerić (TCK) produces 750,000 tons of high-quality cement annually and supplies a substantial portion of Serbia’s and Montenegro’s markets.
TCK belongs to Titan Group which is a multi-regional producer of cement and other related building materials. The company’s headquarters is based in Greece (please see website: http://www.titan.rs).
The Suvo Vrelo Limestone Quarry of TCK is located in the western part of Serbia, in the municipality of Kosjeric, which is 3km away from the town of Kosjeric and 135km away from Belgrade. This quarry supplies limestone to a nearby cement plant (1,2km distance) as raw material feed for the production of clinker and cement. TCK intends to apply a system with transportation for the primarily crushed material through the shaft(s) after changing its mining methods used at the quarry.
Two phases were planned for the implementation of this mining new mining method. The first phase planned is the construction of a tunnel, followed by the second phase, which consists of the construction of two shafts, as illustrated in Figure 1.
It will be necessary to expand the width and the height of the tunnel section, to create the appropriate chambers for the points that join between the shafts and the tunnel (Figure 1).
The first phase was the construction of the tunnel, which started on 12th November 2015 and were completed on 11th November 2017.
The second phase, which is due to start in the spring of 2018, consists of the construction (excavation and support/lining) of the two shafts. are part of the overall system application for the new mining method that will be used at the Suvo Vrelo limestone quarry.
The project includes the construction of the following objects:
a) Shaft S1: Excavation, temporary support and the final lining. The excavation of the shaft will be done from bottom to top with a raise boring machine
b) Shaft S2: Excavation, temporary support and the final lining. The excavation of the shaft will be done from bottom to top with a raise boring machine.
Supervision of a first phase is successfully finished, with following KPI’s:
– Zero Harm
– Zero lost days
– No environmental pollution
– High-quality standards
