Item type:Article, Access status: Open Access , Węgiel brunatny - perspektywy rozwoju(2007) Kasztelewicz, Zbigniew; Kozioł, Kazimierz; Kozioł, Wiesław; Klich, JerzyThe paper characterizes the most promising Polish lignite deposits. It also presents the possibilities of using it for energy needs in the perspective of a 100-120 years. The study concerns such strategic deposits like »Legnica«, »Gubin - Mosty« and »Złoczew«. The last is the satellite deposit of »Bełchatów« Mine, making the prospect for Bełchatów Power Plant to be active until 2070.Item type:Article, Access status: Open Access , Rekultywacja terenów poeksploatacyjnych w kopalniach węgla brunatnego w Polsce(2007) Kasztelewicz, Zbigniew; Kozioł, Kazimierz; Klich, JerzyThe lignite mining profile in the range of land obtaining and return under mining activities has been presented in the article. Hitherto existing achievements of the mines in reclamation and utilization of pits have been also described.Item type:Article, Access status: Open Access , Zagospodarowanie terenów pogórniczych w KWB »Konin« w Kleczewie SA(2007) Kasztelewicz, Zbigniew; Michalski, Arkadiusz; Jagodziński, Zbigniew; Czaplicki, PawełHitherto existing achievements of the Lignite Mine in Konin in the land reclamation of the post mining activities have been presented in the article. The reclamation and utilization of the already closed pits and those planned to liquidation in the nearest period have been described.Item type:Article, Access status: Open Access , Węgiel brunatny - optymalna oferta energetyczna dla Polski w XXI wieku(2007) Kasztelewicz, Zbigniew; Kozioł, Kazimierz; Klich, JerzyThe article presents the sector of brown coal in Poland on the basis of active mines. The capabilities to satisfy country energy demands, with use of own natural resources, take into consideration also economic factors and safely of energy supplies. Sector development secures alternative employment for thousands professionally active people as well. Lignite as the cheapest fuel, giving guarantee of energy safety for long years, is a leading motto of this paper. In connection with research and development, as well as production possibilities, it makes the optimum offer for Polish power industry.Item type:Article, Access status: Open Access , Wydajność i czas pracy koparek wielonaczyniowych w kopalniach węgla brunatnego w Polsce(2007) Kasztelewicz, Zbigniew; Kozioł, KazimierzThere are two basic parameters which describe excavators work in Polish lignite mines, i.e. efficiency and working time. Presented indices describe individual types of excavators and an average value for all machines operating in the mine. Former exploitation results prove the proper use of their technical parameters, not only on the field of productivity but also time of work. Received values of those parameters are estimated as an European level. This parameters would be even higher when it had been possible to eliminate limitations which appeared periodically at the mine sites. Those limitations appeared in lignite mining industry on two fields: technical and organizational (shortage of parts, shortage of additional machinery, financial limits, standstills in peak energy demand hours, etc.).Item type:Article, Access status: Open Access , Przemienniki częstotliwości w napędach jazdy gąsienicowych maszyn górniczych i węglowych przenośników taśmowych o regulowanej prędkości taśmy(2007) Kasztelewicz, Zbigniew; Reizer, Ryszard; Szymański, Jerzy; Świderski, JerzyIn the paper modern drive solutions of mobile conveyor belts, caterpillar excavators and spills for surface brown coal mine as well as control methods of systems are presented. In classic drive solutions DC motors were used. Nowadays DC motors are replaced by AC motors. AC motor drives are controlled by advanced frequency converters in which scalar and vector control strategies are implemented. Power electronic recuperation units are used for power saving. Recuperation units return electrical energy to the power grid when the induction motors work as generators. The solution of the multi-motor drive system is discussed on the basis of the biggest brown coal excavator in Poland.
