Abstract

System lokalizacji pożarów endogenicznych w zrobach ścian zawałowych w kopalniach węgla kamiennego zawierający rurowe wysięgniki zawałowe charakteryzuje się tym, że w wysięgnikach zawałowych (1) ciągnionych przez obudowę zmechanizowaną ściany, umieszczone są na całej długości wysięgników (1) elastyczne przewody (2), o średnicy zewnętrznej przewodu (2) stanowiącej 90% średnicy wewnętrznej rury wysięgnika (1), które to przewody (2) połączone są z pipetą pomiarową suchą (3) i ssącą pompą powietrza (4).The endogenous fire localization system in the goafs of caving walls in hard coal mines, containing tubular caving booms, is characterized by the fact that in the caving booms (1) pulled by the powered roof support, flexible conduits (2) with a diameter of outer pipe (2) constituting 90% of the inner diameter of the boom pipe (1), which pipes (2) are connected to the dry measuring pipette (3) and the suction air pump (4).
