Silicites of the Blovice complex (Western Bohemia) - their probable genesis, position and utilization
(Polskie Towarzystwo Przeróbki Kopalin, 2022) Beránek, Jiří; Vrublová, Dana; Kapica, Roman; Laštůvková, Markéta
This article deals with silicites (lydites) and their characteristics in the environs of Western Bohemian villages of Skasov, TATIN SMALL LETTER Y WITH ACUTEniste and Kbelnice (former Plzen - jih county). These rocks form long and narrow lenticular bodies in adjacent rocks of the so called Blovice complex (the southern part of Bohemicum, the Tepli - Barrandian part). However, the origin of silicites has not been fully clarified so far. Authors of many studies differ in their opinion - whether these rocks originated either in shallow waters or deep (oceanic) ones, which processes made for this kind of silicites, whether microorganisms were involved, et cetera. In the past, these rocks were quarried because of their excellent properties - hardness, strength as well as a minimum inhibition and utilized for soling forest ways as well as roads and for various constructions including basements, walls and even whole houses - residential and farming ones. In the area, there are many evidences of quarrying lydites in the form of various pits and abandoned quarries with remnants of technology (ramps, service buildings, etc.). The article is supplemented (by / with) original photos as well as simplified maps within the frame of this text.
Real-time positioning of equipment and material tracking of waste streams in surface coal mining – A case study
(Polska Akademia Nauk. Komitet Górnictwa, 2021) Vrublová, Dana; Kapica, Roman; Smelik, Stanislav; Smeliková, Markéta
The primary objective of the case study is to improve monitoring, controlling, planning and managing the extraction processes in surface lignite mining. Under the North Bohemian Lignite Basin (also Most Basin) conditions and the Sokolov Basin, wheeled excavators are deployed as the main technology for extracting coal and overlying rock. Their real-time spatial position can be tracked based on data from GLASS technology, inclinometers, and incremental rotary encoders. The measured data is sent to a remote server and stored in the database. it also serves to calculate volumes of extracted masses. Volume calculation, space position visualisation, and wheel boom movements are performed in KVASoftware. It is a program designed for modelling and d e signing quarries. Knowing the position of the wheel against the digital terrain (quarry), the model is essential for the implementation of many risk-elimination applications, namely with respect to the geological conditions, occupational safety, observance of the profile grade line, the area of extraction, qualitative parameters of the raw material, etc. The mathematical model of backfilling extracted materials is also an integral part of the above-mentioned system.
Influence of liquid hydroxide based additives on suppression of slag formation in granulation furnaces
(Polskie Towarzystwo Przeróbki Kopalin, 2019) Nadkanská, Hana; Závada, Jaroslav; Blažek, Vladislav; Mudruňka, Jaroslav
The article deals with the possibility of limiting slag formation in specific heating plant boilers by adding an additive to the batch. The possibilities of reducing slag formation in energy boilers have already been investigated in laboratory conditions where the addition of the NALCO 8270 additive has not led to demonstrable results [13]. X-ray diffraction and X-ray fluorescence of slag samples collected from granulation boilers were performed within the experiment. Furthermore, calculations of the efficiency of the boilers operated in the heat plant were performed using the indirect method. The efficiency was calculated for boilers without dosing and with additive dosing. The results show that using the additive increases the efficiency of the boiler by about 1%.
Composting in bags
(Polskie Towarzystwo Przeróbki Kopalin, 2019) Mudruňka, Jaroslav; Lyčková, Barbora; Kučerová, Radmila; Glogarová, Veronika; Takáč, David; Ossová, Kidra
A progressive method of processing biodegradable waste is its composting in bags which is considered a very advantageous technology from the financial and operational point of view (Diaz, 2007). This composting method is relatively new, it was developed in Germany in the early 1970's, and consequently it spread into other countries as well. Currently, attempts to apply composting in bags in the Czech Republic are being recorded too. (eurobagging.com, 2011)
The system of tracking the position of the bucket excavator's wheel for prevention of risk situations
(Akademie věd České republiky, Ústav struktury a mechaniky hornin, 2018) Kapica, Roman; Vrublová, Dana; Vrubel, Martin
For companies doing business in mining mineral deposits, ensuring safe work is one of the key tasks (Safety First!). One of the important trends in this area is prevention and endeavour to forestall risk situations. Risks need to be searched, technically described, spatially defined, evaluated and categorized by degree of risk. Complex geological and stability conditions can be one of the sources of persistent and significant risks, which are mainly landslides and rockslides threatening both mining equipment and employees. The problem described in this article and its solution concerns the Most Basin (formerly the North Bohemian Lignite Basin). This is a tertiary basin that was founded in the Oligocene. The main mineral is lignite and mining takes place on the surface. The main excavating machinery in the surface lignite quarries in Europe (Czech Republic, Germany, Poland) is the bucket wheel excavator.
3D laser scanning of mining machines at Nastup Tusimice mine in the Czech Republic
(Taylor & Francis, 2014) Kapica, Roman; Vrublová, Dana; Michalusová, Markéta
3D laser scanning of bucket wheel excavators is useful in identifying key geometric parameters and in the creation of mathematical models. Thus, a compact and highly accurate 3D point model of a bucket wheel excavator was obtained. The evaluation consisted of vectorising their important features. These data were used to visualise the spatial position of excavators and track their movements in real time. Knowing the position of excavators, particularly the displacement of the bucket wheel relative to the digital terrain model (opencast mine), coupled with the geological model is important for mine management and calculation of volumes of extracted materials in real time. The 3D laser scanning measurements were carried out at Severočeské Doly mines.
