Abstract
The Leon IV shaft in Rydułtowy Mine is one of the last mining shaft deepened from the surface in Polish hard coal mining industry, extended and finally equipped with mine shaft hoist installation. This investment will allow the construction of the exploitation level 1150 m and availability of next hard coal seams to the level 1200 m, what will guarantee possibility of the exploitation of over 65 mln ton of coal, as well as continuous operation of the coal mine up to 2040. This shaft was an object, in which a number of innovative solutions were implemented during its construction, due to actual level of technical and material technologies. Elastic guiding of mining cages was applied for the shaft furniture as a one of the first time in Polish mining industry, what in comparison with rigid shaft furniture is considerably cheaper and has many other advantages. A number of innovative solutions, which have not been used before in Polish mining shaft building were applied during the Leon IV shaft building period – basal deepening in the years 1990-1998 and additional deepening in the years 2013-2017. Deepening of active mine shaft comprises number of specific and very difficult operations, because it calls for use of untypical devices securing hoist operation in the shaft, as well as special technology tailored to actual technology of the deepened shaft face. In case of the Leon IV shaft building, the special attention was paid for works related with the shaft deepening and extension of the shaft hoists, where elastic guiding of mining cages was applied for the first time. Finally, the shaft deepening and extension of the shaft hoists will allow development of the new transport level at the depth of 1150 m, what in turn will improve condition of the mine ventilation and it will result in personnel transport time shortening.
