The diploma thesis is focused an the field of stone splitting and especially the splitting tools of hydraulic splitting machines, a splitting knife, thanks to which the stone is split. The first part describes the base material used for knife splitting production. Both types of steel and cemented carbides are described below. Followed by introduction of stone splitting and methods of stone extraction. This part is closed by an overview of products made of splited stone. The experimental part deals with measurements, which was aimed on demonstraion of the impact on the used materials and on the lifetime of the splitting knife. Also on the influence of the knives edge and the quality of the final product. The characteristics of the stone, used in the measurements, were subjected to tests, which were carried out in the Hořice test facility and the results are ilustrated in the graphs. In the thesis is also described the operation of the Sumrakov quarry from where the measured tools are. Also stone splitting machines ,manufactured by Gestra CZ s.r.o., have been thoroughly analyzed.

The diploma thesis is focused on environmental tools related with rural development. This concept is realized in the conditions of a self-government entity - Žlutava municipality and a private company - Kamenolom Žlutava s. r. o. in Zlin region. The proposition of this thesis is divided into theoretical framework of environmental tools and subsequent evaluation of used tools, innovative designing of environmental resources. SWOT analysis was used as an analytic method and after that specific environmental tools were assembled and implemented according to the results. Diversification of these environmental tools was created separately for each subject but also for both subjects altogether. Concrete results represented realistic proposal of these environmental tools: register of legal requirements, research of subsidies, environmental education, green public procurements. The outputs and outcomes of the diploma thesis will be used by the mayor of the Žlutava municipality and the managing director of the Kamenolom Žlutava s. r. o.

Selected quarries and adjacent areas of xerophilous grassland in Bohemian karst were examined for the presence of velvet spider burrows. Selected microhabitat valuables were collected and their significance for ladybird spider analyzed.

This thesis deals with a flooded stone quarry near the village Hradec u Stodu. This quarry is examined from historical, biological and educational point of view. The thesis contains informations about history, ecology and environmental conditions of the examined lokality, results of geological, faunistic and floristic investigation and suggestion on the utilization of this lokality for biology and geology education in the field; work sheets for pupils are completed too. Found organism photogalery is attached in appendices. DVD containing a thorough photodocumentation is also a part of this thesis.
