Abstract
Światłowodowy układ pomiarowy do wykrywania zagrożeń górniczych, zwłaszcza pożarowych oraz tąpań, umieszczony w górotworze, wyposażony w czujniki i skrzynkę kontrolno - pomiarową połączoną z jednostką sterującą charakteryzuje się tym, że stanowi światłowodowy kabel pomiarowy (1) w chodniku nadścianowym (4) i/lub podścianowym (3), którego pętle pomiarowe (12) umieszczone są w otworach pomiarowych w ociosie (8) o głębokości od 1 mb do 2 mb, rozmieszczonych w odległości 30 - 50 mb, przy czym calizna górotworu (2) stanowi ocios przeciwny do calizny ociosu ścianowego (9), światłowodowy kabel pomiarowy (1) umieszczony jest w zrobach (7), równolegle do chodnika nadścianowego (4) i/lub podścianowego (3), przy czym pierwsza pętla pomiarowa (5) światłowodowego kabla pomiarowego (1) rozmieszczona jest w odległości 25 — 50 mb poniżej chodnika nadścianowego (4) i/lub powyżej chodnika podścianowego (3), druga pętla pomiarowa (5) światłowodowego kabla pomiarowego (1) rozmieszczona jest w odległości 75 - 100 mb poniżej chodnika nadścianowego (4) i/lub powyżej chodnika podścianowego (3), trzecia pętla pomiarowa (5) światłowodowego kabla pomiarowego (1) rozmieszczona jest w odległości 150 — 175 mb poniżej chodnika nadścianowego (4) i/lub powyżej chodnika podścianowego (3), a każda z pętli pomiarowych (5) światłowodowego kabla pomiarowego (1) wyposażona jest w czujniki (6), przy czym pętla pomiarowa powrotna (11) rozmieszczona jest na powierzchni spągu chodnika nadścianowego (4) i/lub podścianowego (3), natomiast końcowy i początkowy odcinek światłowodowego kabla pomiarowego (1) umieszczony jest w skrzynce kontrolno - pomiarowej (10).The fiber-optic measuring system for detecting mining hazards, especially fire and rock bursts, located in the rock mass, equipped with sensors and a control and measurement box connected to the control unit, is characterized by the fact that it is a fiber-optic measuring cable (1) in the over-wall heading (4) and / or sub-wall (3), whose measuring loops (12) are placed in measuring holes in the side wall (8) with a depth of 1 m to 2 m, spaced at a distance of 30 - 50 m, with the entire body of the rock mass (2) being the opposite side to the body side of the side wall (9), the fiber-optic measuring cable (1) is placed in the goafs (7), parallel to the over-wall (4) and / or under-wall heading (3), with the first measuring loop (5) of the fiber-optic measuring cable (1) arranged is at a distance of 25 - 50 m below the over-wall heading (4) and / or above the under-wall heading (3), the second measuring loop (5) of the fiber optic measuring cable (1) is located at a distance of 7 5 - 100 m below the over-wall walkway (4) and / or above the under-wall walkway (3), the third measurement loop (5) of the fiber optic measurement cable (1) is located 150 - 175 m below the over-wall walkway (4) and / or above of the sub-wall walkway (3), and each of the measurement loops (5) of the fiber-optic measurement cable (1) is equipped with sensors (6), while the return measurement loop (11) is located on the floor of the top-wall (4) and / or sub-wall walkway (3), while the end and the beginning section of the fiber optic measurement cable (1) is placed in the control and measurement box (10).
