Abstract
Sposób wykrywania pożarów endogenicznych w górnictwie podziemnym węgla kamiennego polega na tym, że w co najmniej jednym chodniku przyścianowym (1) umieszcza się co najmniej jeden światłowód (2), który instaluje się w rurowej osłonie (3) na planowanej długości wyrobiska eksploatacyjnego (4), przy czym światłowód (2) włącza się w centralny układ monitoringu zagrożeń pożarowych (CUM). W miarę postępu wyrobiska ścianowego (4) pozostawia się światłowód (2) wraz z osłoną (3) w zrobach (5) i prowadzi monitoring temperatury w celu wykrycia wzrostu temperatury w zrobach (5). Wynalazek dotyczy również układu do wykrywania pożarów endogenicznych w górnictwie podziemnym węgla kamiennego.The method of detecting endogenous fires in underground coal mining consists in the fact that at least one longwall (1) contains at least one optical fiber (2), which is installed in a tubular sheath (3) along the planned length of the excavation (4) , the optical fiber (2) is included in the central fire hazard monitoring system (CUM). As the longwall excavation progresses (4), the optical fiber (2) along with the cover (3) is left in the goaf (5) and temperature monitoring is carried out to detect a temperature increase in the goaf (5). The invention also relates to a system for detecting endogenous fires in underground coal mining.
