Abstract

Opisano, przedstawione na rysunku, systemy i sposoby monitorowania stanu stropu kopalni przy użyciu ścianowego systemu wydobywczego. Wiele podpór zmechanizowanych obudów ścianowych jest poddawana regulacji przez zastosowanie do stropu kopalni regulowanego ciśnienia obudowy. Stan stropu kopalni monitoruje się w oparciu o regulowane ciśnienie obudowy zastosowane do stropu przy użyciu odpowiadającego siłownika każdej zmechanizowanej obudowy ścianowej. W pewnych realizacjach stan stropu kopalni jest monitorowany przez generowanie i analizowanie graficznej mapy nacisku opartej na regulowanym ciśnieniu obudowy zastosowanym przez każdą zmechanizowaną obudowę ścianową oraz względnym położeniu wrębiarki poruszającej się przez przodek. W pewnych realizacjach zdarzenia zawału stropu wykrywa się w oparciu o chwilowo podobne zmiany regulowanego ciśnienia obudowy zastosowanego przez wiele sąsiednich zmechanizowanych obudów ścianowych, jak wskazano przez graficzną mapę ciśnienia.
