Návrh technologie ražení spojovací chodby v historickém Dolu Jeroným

Abstract

In today's hectic times, it is necessary to look back into history and think about the technical monuments left to us by our ancestors. It is in our own interest to preserve these monuments not only as a proof of a technical maturity of that times, but especially to unlock them to the public and to the future generations. This technical monument is the Jeroným Mine which is a copybook example of a medieval mining. A lot of effort and building work is required to open the mine to the schema_dspacedb. One of the building work is a crosscut which will provide a passage corridor between two main units of the mining complex and it will connect old mines (SDD) with abandoned mines (ODD). This work describes a driving technology design of a passage corridor between SDD and ODD. The design is based on the IG survey carried out along the crosscut. Throughout the excavation process penetration into other water bearing old mines is rather expected. The risk of a water outbreak and inrush of mud during the excavation is high. Therefore it is important to revise the proposed technology and procedures identified according to the conditions in-situ.
