Abstract

Sposób zwalczania wybuchu pylu weglowego w podziemnych wyrobiskach górniczych charakteryzuje sie tym, ze w swietle wyrobiska (1) rozmieszcza sie przeciwwybuchowe zapory pylowe (2), skladajace sie z hermetycznych pojemników wypelnionych uprzednio porcjami pylu, najkorzystniej pylu kamiennego. Zapora sklada sie z hermetycznych pojemników z uchwytami (3), wypelnionych pylem, które zawieszone sa wahliwie w wyrobisku (1), najkorzystniej na odrzwiach obudowy (1a), za pomoca zawiesi hakowych (5). Hermetyczne pojemniki z uchwytami (3) wyposazone sa w listwe wzmacniajaco - usztywniajaca (3a) z uchwytami (3b) w formie otworów.The method of combating the explosion of coal dust in underground mining excavations is characterized by the fact that in the light of the excavation (1) there are explosion-proof dust barriers (2), consisting of airtight containers previously filled with portions of dust, most preferably stone dust. The dam consists of hermetic containers with holders (3), filled with dust, which are suspended pivotally in the excavation (1), most preferably on the housing legs (1a), using hook slings (5). Hermetic containers with handles (3) are equipped with a reinforcing - stiffening strip (3a) with handles (3b) in the form of holes.
