Description
Przedmiotem wynalazku jest zapora pylowa posiadajaca przytwierdzone do obudowy podpórki podtrzy¬ mujace pozostale elementy niezamocowane stosowane zwlaszcza w górniczych wyrobiskach korytarzowych o zmieniajacym sie w czasie przekroju poprzecznym.The subject of the invention is a dust dam having three supports attached to the housing having other unfastened elements, used especially in mining corridors with a cross-section that changes with time.
Znane i powszechnie stosowane sa zapory pylowe zlozone z podpórek przytwierdzonych do obudowy wyrobiska i ulozonych na nich bez zamocowania klocków na których spoczywa podstawa nakryta pomostem skladajacym sie z luznych desek ulozonych obok siebie. Znane sa równiez zapory, które maja pomost wykonany z podluznych desek spoczywajacych na deszczulkach ulozonych na szynach. Szyny sa przytwierdzone do obudowy wyrobiska albo ulozone na podporach. Skutecznosc dzialania znanych zapór niezaleznie od typu jest znacznie ograniczona na skutek zmniejszenia sie w czasie przekroju wyrobiska powodowanego konwergencja skal. Zmniejszony przekrój wyrobiska powoduje zakleszczanie podstawy (szyn) zapory której uniemozliwia przy wybuchu pylu weglowego zrzucenie pólki z pylem kamiennym i rozproszenie pylu kamiennego.Dust barriers composed of supports attached to the housing are known and commonly used excavations and blocks placed on them without fixing them, on which the platform covered with a platform rests consisting of loose planks placed next to each other. There are also dams that have a bridge constructed from elongated boards resting on slats placed on rails. The rails are attached to the excavation covers or placed on supports. Known firewalls perform well regardless of their type significantly reduced due to the reduction of the cross-section of the excavation over time caused by convergence scales The reduced cross-section of the excavation causes jamming of the base (rails) of the dam, which is prevented by the coal dust explosion to knock down the stone dust shelf and disperse the rock dust.
Istota rozwiazania zapory pylowej wedlug wynalazku polega na tym, ze zapora ma podstawe skladana, której wewnetrzne konce wyposazone w korzystnie przyrnocowane prowadzenia, wzajemnie na siebie nachodza i wzgledem siebie sie przesuwaja.The essence of the dust dam solution according to the invention consists in the fact that the dam has a foldable base, the inner ends of which are provided with advantageously connected leads overlap each other and they move in relation to each other.
Zaleta zapory pylowej wedlug wynalazku jest mozliwosc zachowania stalej swobody ruchu elementów zapory w kazdych warunkach górniczo-geologicznych, umozliwiajaca uruchomienie jej pólek juz przy najslab¬ szym podmuchu spowodowanym wybuchem.The advantage of the dust barrier according to the invention is that the elements can be freely moved continuously dam in all mining and geological conditions, enabling the launch of its shelves at the weakest blast caused by the explosion.
Zapora pylowa wedlug wynalazku jest uwidoczniona w przykladzie wykonania na zalaczonym rysunku, na którym fig. 1 przedstawia zapore w widoku z przodu a fig. 2 - sama podstawe zapory w widoku z góry.The dust barrier according to the invention is shown in the example of the embodiment in the attached drawing, in which fig. 1 shows the dam in front view and fig. 2 shows the base of the dam itself in plan view.
Zapora pylowa sklada sie z podpórek 1 przytwierdzonych do obudowy lukowej, klocków 2 ulozonych na nich równolegle do ociosu wyrobiska korytarzowego, podstawy 3 koncami zewnetrznymi wspartej na klockach 2 z koncami wewnetrznymi zachodzacymi na przemian na siebie. Konce wewnetrzne zaopatrzone sa w klocki 4. ograniczajace dlugosc maksymalna podstawy 3, oraz w prowadzenia 5 boczne przeznaczone dla przesuwu wzdluz swobodnych konców wewnetrznych drugiej czesci podstawy 3. Podstawa 3 pokryta jest deszczu f kami 6 ulozonymi luzno obok siebie.2 101 697 Zapora zabudowana jest w ten sposób, ze zewnetrzne konce jej podstawy 3 nie stykaja, sie bezposrednio z obudowa wyrobiska. Zmniejszenie przekroju wyrobiska spowodowane konwergencja skal doprowadza wprawdzie do zetkniecia sie podstawy 3 z obudowa ale w zadnym wypadku nie spowoduje jej zakleszczenia, poniewaz nastapi przesuniecie wewnetrznych konców wzgledem siebie (skrócenie dlugosci podstawy).The dust barrier consists of supports 1 attached to the hatch housing, 2 blocks placed on the them parallel to the side of the corridor excavation, the base with 3 external ends supported on 2 blocks with inner ends overlapping each other. Inside ends are provided with blocks 4. 3 limiting the maximum length of the base, and 5 side guides for travel along the free inner ends of the second part of the base 3. The base 3 is covered with rain grooves 6 placed loosely next to each other. 2 101 697 The dam is built in such a way that the external ends of its base 3 do not touch, but directly with excavation lining. The reduction of the excavation cross-section caused by the convergence of the scales leads even if the base 3 comes into contact with the housing, but in no case will it jam, because there will be a shift of the inner ends relative to each other (shortening the length of the base).
Elastyczna regulacja dlugosci podstawy 3 pozwala na utrzymanie stalej skutecznosci uruchamiania pólek zapory przez podmuch wybuchu.Flexible adjustment of the length of the base 3 allows to maintain a constant effectiveness of the activation of the dam shelves by the blast of the explosion.
