Abstract

Przedstawiono układy i sposoby wykrywania pełzania przodkowego dla ścianowego systemu wydobywczego (100). Układ zawiera urządzenie wykrywające zamontowane w chodniku podścianowym i sprzężone z urządzeniem wykrywającym. Sterownik ustala położenie sprzęgu przenośnik zgrzebłowy podścianowy - przenośnik ścianowy w oparciu o sygnał z pierwszego urządzenia wskazującego, ustala położenie linii chodnika podścianowego w oparciu o sygnał z urządzenia wskazującego chodnika podścianowego, oraz ustala położenie przenośnika taśmowego w oparciu o sygnał z urządzenia wskazującego przenośnika taśmowego. Ponadto sterownik ustala pierwszą odległość między położeniem sprzęgu przenośnik zgrzebłowy podścianowy - przenośnik ścianowy a linią chodnika podścianowego, oraz drugą odległość między położeniem przenośnika taśmowego a linią chodnika podścianowego. Sterownik generuje wskazanie pełzania przodkowego w oparciu o pierwszą odległość oraz drugą odległość.
