Inclined belt conveyor of aggregates
Zavadil, Milan ; Malášek, Jiří (referee) ; Škopán, Miroslav (advisor)
The aim of this work is the design of helical conveyor belt for transport of building stone and recycled aggregate with a maximum grain size of 150 mm. Work includes a characteristic of some parts of the conveyor functional calculation, determine the key dimensions and design of power according to ISO 5048. Further strength calculation was carried out certain parts of the conveyor and assembly drawn in overall conveyor subassembly and stretching equipment.

Old quarries in Brno city: a bridge between natural and cultural heritage
Kubalíková, Lucie
Thanks to its position on the border of two important geological units (Bohemian Massif and Western Carpathian), Brno City possesses high lithological and morphological diversity. These geodiversity aspects significantly influenced the historical development of the city, its urban settings and the availability or use of natural resources. The history of exploitation of natural resources begins in the Palaeolothic (flints on Stránská skála), however, the quarrying itself dates to the Early Middle Age – e.g. the extraction of limestones at Hády and Stránská skála, Old Red sandstones and conglomerate at Červný kopec. Currently, there are tens of abandoned quarries and pits within Brno city, which give testimony about the geological history and history of use of the natural resources. These extraction sites are often protected by law as Natural Monuments or Reserves or Important Landscape Elements. Thanks to their values they represent an important resource of the knowledge in the Earth-sciences (paleontology, stratigraphy, speleology), but they have often the significance from the cultural and historical point of view (use of the material for local architecture, anthropogenic landforms related to mining, influence on the urban development). Quarries thus represent a bridge between natural and cultural landscape features or between natural and cultural heritage. The research on quarries (or extraction sites) can bring new insights into the problem of an integrated approach to the protection and conservation of natural and cultural heritage.
