The longest tunnel in the Czech Republic has interconnected the Karviná and Darkov Mines hundreds of meters underground

Ostrava (January 10, 2013) – A unique mining excavation, almost one-third longer than the longest Czech highway tunnel, was carried out by the miners almost 900 meters underground between the Karviná and Darkov Mines. A three-kilometer long corridor, in some locations almost 9 meters wide and 5.5 meters high, will bring OKD significant savings and new possibilities of coal, material and personnel transportation in the future.

 

According to the OKD management, this is a strategic investment. “The crosscut will allow us to transport coal mined at the ČSA site of Karviná Mine to the modern coal preparation plant of the Darkov Mine, whose capacity has not been fully utilized so far. The shutdown of the Karviná Mine coal preparation plant, which is at the end of its life time, will bring, apart from savings to our company, also significant improvements of environmental parameters for the Karviná Region because the Darkov coal preparation plant is equipped with state-of-the-art world-class technology, whose environmental impacts are minimal,” added Ján Fabián, Chief Executive Officer and Chairman of the Board of Directors, OKD.

 

The mine surveyors’ accuracy was also extraordinary because they had to ensure that the mine corridors, cut in parallel from both the mines, were interconnected. “They hit the target very well. There was only a very small deviation in the order of some centimeters, which is really admirable in view of the local conditions,” Jan Matula, Chief Planning and Engineering Officer, OKD, appreciated the work completed by the specialists.

 

Originally, the crosscut should have been completed late last year, but in fact, both the corridors were interconnected into one as early as December 12, 2012. During the mining excavation, the miners consumed over 10,000 tons of concrete, installed over 9,000 meters of piping and used over 4,000 tons of materials. At present, the corridor is being equipped with conveyors and other necessary equipment, and it should be in full service from July.
