Zpravodaj Hnědé uhlí 2016, 56(2)
The article deals with the status of the quality in the strategic management of the organization, responding to the developments in the Czech Republic in the last 25 years in the field of quality. It is focused on the introduction of the processes contained in the Blue Guide in the Czech Republic, including some instruments such as certification, accreditation and conformity assessment. The second area is the national quality policy in the Czech Republic as defined by the Board of quality of the Czech Republic. The main aim of this work is the implementation of the research and the findings/verification, whether and how it is used in the strategic...
Measuring of the torque on the shafts of input pinions of the wheel drive gear box of the bucket wheel excavator KU 800.18/K99

Zpravodaj Hnědé uhlí 2016, 56(2)
The article describes the direct measurement of the torque on input shafts pinions of the wheel drive gearbox of the excavator KU 800.18/K99, which was implemented at the beginning of the year 2016. The direct measurement utilises connection of the classic strain-gauge sensors with the modern measuring microelectronic technology. The article provides the basic principles of measurement, description of the installation of sensors and measuring apparatus, measuring results and lessons learned.

Zpravodaj Hnědé uhlí 2016, 56(2)
The article summarizes existing knowledge on the occurrence, geological and geotechnical characteristics of difficult mineable positions in the overburden soils of the Most basin and the possibilities of their detection. The provided summary is the partial output of the first phase of the European research project focused on the highest possible reduction in the fault frequency of bucket wheel excavators working in these difficult mining conditions including the non-minable positions and the geological structure with excessive cutting resistance.
The alluvial system of Libouš affected by synsedimentary peat compaction (lower Miocene, Most Basin)

Zpravodaj Hnědé uhlí 2016, 56(2)
The paper describes geological structure and the development of the one of evolution stages of the Miocene alluvial system of so called "Žatec Delta". This alluvial step influenced peat formation in the area of the current open pit mine "Doly Nástup Tušimice" (Libouš opencast) in the western part of the Most Basin. Asymetric beds of silty channel deposits together with formation of growth faults indicates influence of synsedimentary compaction of underlying peat. Growth faults were formed especially on the periphery of fluvial channel in places of the highest gradient of river sediment load. The most intense synsedimentary compaction of underlying...
