    Badania elektromechanicznych zespołów napędowych zwałowarki ZGOT
    (Wydawnictwa AGH, 2009) Anuszczyk, Jan; Jabłoński, Mariusz
    Paper presents the results of laboratory and industrial testing of the caterpillar drives of the loading feeder of the spreader ZGOT-15400.120 working in the strip pit Szczerców of the KWB »Bełchatów« Mine. The electromagnetic and electromechanical transient states in the drive systems have been analysed. A new conception of sensorless steering algorithm modification in the CUVC bord controlling of converter has been introdused. After proposed solution the decrease of motors torque oscilations and mechanical vibrations in the low frequencies range of converter work was obtained.

    Zagrożenia osuwiskowe w Zakładzie Górniczym KWB »Bełchatów«. Prognozowanie, monitoring oraz ograniczanie zagrożeń na przykładzie rejonu XIII/N na zboczu transportowym
    (2007) Czarnecki, Leopold; Jończyk, Waldemar; Organiściak, Barbara
    The paper elaborates on KWB »Bełchatów« pit northern sidewall stability issues, related with complex geological structure of the subject area. It describes rock-mass structure of the hazardous area and adjacent areas. Presented are three variants of securing the pit's transportation sidewall, being currently under threat of the large scale rock-slide. Characterized is approved for realization, the way of securing the sidewall by creating the spreader-made ground-buttress. Described are also the results of survey measurements of surface and a deep ground deformations, carried out as part of the first stage of slope stabilising works.
