Abstract
Wynalazek dotyczy sposobu wykonania kanalu likwidacyjno-wyjazdowego kompleksu zmechanizowanego z górniczego wyrobiska scianowego w podziemiach kopalni glebinowej z zagrozeniem metanowym w obudowie lukowo-prostokatnej (1), wzmocnionej we wczesniejszej fazie szybkopostepowego biegu górniczego wyrobiska scianowego (5) z kompleksem zmechanizowanym strugowym w kierunku do tego kanalu likwidacyjno-wyjazdowego tak, aby w swej fazie koncowej zblizajacy sie front wyrobiska scianowego (5) mógl dojechac i bezposrednio wjechac do wczesniej przygotowanego kanalu likwidacyjno-wyjazdowego w obudowie lukowo-prostokatnej (1), wzmocnionej w swej czesci stropowej podciagami stalowymi oraz kotwami strunowymi (3a,3b,3c) o nosnosci korzystnie 320 kN. Front wyrobiska scianowego (5) wjezdza etapami z kompleksem zmechanizowanym po wykonaniu odcinkami skosowania (6) pod spodem swego wylotu (5a) do wlotu bocznego obudowy lukowo-prostokatnej (1) kanalu likwidacyjno-wyjazdowego w swojej koncowej fazie stopniowo poprzez przesuwajacy sie punkt jego styku z tym kanalem pod odpowiednim katem.The invention relates to the method of constructing the liquidation-exit channel of a mechanized complex from a mining wall excavation in the underground of a soil mine with a methane hazard in a rectangular arch hatch (1), reinforced at an earlier stage of the high-speed run of the mining excavation wall (5) with a mechanized plow complex in this direction the decommissioning and exit channel so that in its final phase the approaching front of the wall excavation (5) can reach and directly enter the previously prepared decommissioning and exit channel in a rectangular hatch (1), reinforced in its ceiling with steel beams and string anchors (3a, 3b, 3c) with a bearing capacity of preferably 320 kN. The front of the wall excavation (5) enters in stages with the mechanized complex after making bevelled sections (6) underneath its outlet (5a) to the side inlet of the hatch-rectangular housing (1) the liquidation-exit channel in its final phase gradually through the moving point of its contact with this channel at the right angle.
