Economic analysis of the company Výtahy, s.r.o.
Konečný, Petr ; Klečka, Jiří (advisor) ; Sobotka, Viktor (referee)
This thesis economically analyses the company Výtahy, s.r.o. First there are some pages about the company itself, what it produces, few words about its history and crucial moments and the situation on the market. In the theoretical part the chosen methods of economic analysis are depicted. Practical part focuses on the company Výtahy, s.r.o. The horizontal and vertical analysis of the assets, liabilities and profit and loss account is shown. There is a calcuation of net working capital and its demand. The effectiveness of the company is measured also by a system of logical inequations. Important part is devoted to ratio indexes -- rates of profit, return on sales or assets, solidity of the firm, equity ratio or turnaround period of assets or inventories. The economic value added is counted by two methods -- with the model from Department of industry and trade and with the net operating profit after tax model. I applied several of financial health models to predict and analyse, if the company is doing good or bad. I compared the competing companies among themselves through the last five years based on four criteria. And I used three methods for the final order of the companies. The last comparison is done thru Spider analysis and it shows the economical situation of three Czech elevator companies in last two years.
Stability control of double used roadways with combined support
Šňupárek, Richard ; Konečný, Petr ; Ptáček, Jiří ; Koníček, Petr
Double using of roadways in coal mines requires special kinds of support. Combined support consisting from bolting and steel arch supports is described. The paper contains methods of dimensioning and design of combined support in conditions of Ostrava Karviná coal basin.
Strategy of longwall preparation and of the possibility of support strengthening in the coal mines with the rock burst risk
Ptáček, Jiří ; Konečný, Petr ; Šňupárek, Richard ; Koníček, Petr
The contribution presents conclusions of the research project called Miners protection against rock burst in the gates and measures to avoid them after checking the rock burst danger, supported by Czech Mining Authority. The results of research on the reinforced break through support and research on the way and strategy of longwalls driving in the conditions of rock burst danger are described.
Evaluation of subsidence caused by application of single-entry room-and-pillar mining method with stable pillars between mined out drifts using the Continuous Miner Technology with full roof bolting. Stage 2 – Development of model for stable pillar dimensioning for single-entry room-and-pillar mining method with Continuous Miner Technology and calculation of surface deformation
Konečný, Petr ; Byczanski, Petr ; Koníček, Petr ; Ptáček, Jiří ; Šňupárek, Richard ; Velička, Vilém ; Zeman, Vladislav
The model solution of stable pillars dimensioning for single-entry room-and-pillar mining method with Continuous Miner Technology is described. Consequently, the parameters of subsidence trough are calculated as an example caused by application of that technology in selected conditions of Ostrava-Karviná Coal Basin.
Evaluation of subsidence caused by application of single-entry room-and-pillar mining method with stable pillars between mined out drifts using the Continuous Miner Technology with full roof bolting. Stage 1 – Development of mathematical model and calculation of expected surface deformation

Evaluation of subsidence caused by application of single-entry room-and-pillar mining method with stable pillars between mined out drifts using the Continuous Miner Technology with full roof bolting. Stage 1 – Development of mathematical model and calculation of expected surface deformation.
Possibilities of double use of longwall drifts at the Paskov, ČSM and Karviná Collieries
Konečný, Petr ; Ptáček, Jiří ; Šňupárek, Richard ; Velička, Vilém ; Zeman, Vladislav ; Petroš, V. ; Hudeček, V. ; Šancer, J. ; Dvořáček, J. ; Slivka, V.
Analysis of the possibilities of double use of longwall drifts at the Paskov, ČSM and Karviná Colliery with respect to the mining and natural conditions. Conditions for double use longwall drifts, foreign experiences.
Guideline for project planning and support design of longwall drifts intended for double utilization
Konečný, Petr ; Koníček, Petr ; Ptáček, Jiří ; Šňupárek, Richard ; Velička, Vilém ; Zeman, Vladislav
Guideline with principles for selection, realisation and mine support of longwall drifts which are intended for double utilization focused on combined arch and bolt support.
Ochrana zaměstnanců před důlními otřesy v dlouhých důlních dílech a stanovení opatření při zjištění nebezpečných stavů při vedení a provozu důlních děl s cílem zabránit vzniku otřesu. Projekt č. 44-06. Dílčí zpráva o výsledcích řešení etapy č. 5
Konečný, Petr ; Ptáček, Jiří ; Šňupárek, Richard ; Velička, Vilém ; Zeman, Vladislav ; Bonczek, Č. ; Dvorský, P. ; Holečko, J. ; Koníček, P. ; Przeczek, A. ; Stoniš, M.
Řešení projektu se týká ražeb chodeb a úvodních prorážek pro přípravu nových porubních bloků. Snahou je nalézt nové způsoby preventivních opatření, které by v nich omezily na nejmenší možnou míru riziko otřesů. Kromě toho se v projektu řeší problematika zpřesnění lokace seismických jevů a rovněž zkoumá možnost použití vývrtů po trhací práci pro tlakové zavlažování v rámci protiotřesové prevence.
