Abstract
Przedmiotem wynalazku jest okładzina górnicza typu AP, to jest lekka i podatna oraz typu BP, to jest ciężka i podatna, przeznaczona do wykonywania obudowy odrzwiowej górniczych wyrobisk korytarzowych we współpracy z obudową chodnikową wykonaną z kształtowników stalowych typu TH oraz V, zwłaszcza V-25, V-29, V-36 i V-44. Okładzina (1) charakteryzuje się tym, że ma kształt graniastosłupa czworokątnego prostego o podstawie prostokąta lub rombu i wykonana jest z mieszanki betonowej o klasie wytrzymałości na ściskanie co najmniej C 25/30 oraz stopniu wodoszczelności co najmniej W2, przy czym mieszanka betonowa zawiera zbrojenie rozproszone w postaci włókien szklanych i/lub polipropylenowych i/lub polietylenowych i/lub korzystnie bazaltowych, w ilości od 0,1 do 2,0% w stosunku do masy mieszanki betonowej, ponadto okładzina (1) zawiera zbrojenie główne w postaci co najmniej jednego pręta zbrojeniowego (3), o średnicy w przedziale od 6 do 16 mm i długości dopasowanej do długości okładziny, wykonanego z kompozytu bazaltowego lub z włókien szklanych, lub w postaci co najmniej jednego pasa kompozytowego, wykonanego na bazie rowingu bazaltowego lub szklanego, o szerokości od 30 do 45 mm, grubości od 3 do 5 mm oraz długości dopasowanej do długości okładziny.The subject of the invention is a mining AP facing, i.e. lightweight and flexible, and BP type, i.e. heavy and flexible, intended for making the casing of mine corridor headings in cooperation with a pavement casing made of steel profiles TH and V, especially V-25, V-29, V-36 and V-44. The cladding (1) is characterized by the fact that it has the shape of a rectangular prism with a rectangular or rhombic base and is made of a concrete mix with a compressive strength class of at least C 25/30 and a watertightness level of at least W2, the concrete mix containing dispersed reinforcement in the form of glass and / or polypropylene and / or polyethylene and / or preferably basalt fibers, in an amount of 0.1 to 2.0% by weight of the concrete mix, in addition, the cladding (1) contains the main reinforcement in the form of at least one bar reinforcing (3), with a diameter in the range of 6 to 16 mm and a length matched to the length of the cladding, made of basalt composite or fiberglass, or in the form of at least one composite strip, made on the basis of basalt or glass roving, with a width of 30 to 45 mm, 3 to 5 mm thick, and length matched to the length of the cladding.
