Abstract:
Vertical shaft sinking for underground transportation purposes is a very demanding technological process in mining and geotechnology, which requires specific and specially designed technological equipment. At the same time it is a technological process that humanity deals with from its beginning, since mining is one of the oldest industries in the world. The aim of the article “Vertical shaft sinking NOP II for a new ventilation purposes in Velenje Coal Mine is to show the technical challenge of this project. Velenje Coal Mine has made up the decision for the sinking of a new ventilation shaft, depth of 393 meters. We started with the preparation works in 2011 and with a shaft sinking in 2012. The aims of the paper is to show the preparatory work before the start of the actual work, describes the equipment required for the vertical shaft sinking, it shows the primary and secondary support measurements and monitoring of mining work at such facility. With this article, we would like to represent the mining field of shaft sinking in Slovenia.
