Abstract

The thesis summarizes a brief history of the Lazy Mine and its nearest future, presently it is plant Lazy, Karviná Mine. On the basis of found out information I have suggested in the first stage to carry out the clearance of intake shaft No. 5 at the plant Lazy. Term for realization of clearance of shaft No. 5, I suggested in the course of 2012, which is over its need. Fresh air supply to the workplace will be secured with intake shaft No. 2 sufficiently. The introduction of practical part of my thesis deals with a comparison of several methods of clearance of main workings and evaluates the best way. From the point of view financial and working difficulties I assessed the most appropriate method of clearance, which is the backfilling of shaft with unconsolidated material. At processing of my dissertation, I drew on my experience and practical knowledge regarding the clearance of shafts Orlova 1, Orlova 2, Pit 3 (Majerka) and DO I shaft of ex-mine Doubrava. The result of my work is an overview of basic working operations for ensuring the required goal, list and amount of material needed for realization of construction of retaining walls and stopping dams. This is based on the budgets and own authentic photographs.
