Pierwszenstwo: Zgloszenie ogloszono: 30.05.1973 Opis patentowy opublikowano: 17.04.1975 75930 KI. 5b,41/00 MKP E21c 41/00 [cTYTELNIAr Urzedu Patentowego falUnl fennmrtliU) it,,,,, 1 Twórcy wynalazku: Zbigniew Klonowski, Franciszek Rakowski Uprawniony z patentu tymczasowego: Kopalnia Wegla Kamiennego „Miechowice", Bytom (Polska) Sposób eksploatacji grubych pokladów na warstwy systemem scianowym ze sztucznym stropem Przedmiotem wynalazku jest sposób prowadzenia eksploatacji systemem scianowym na zawal gru¬ bych pokladów szczególnie przy eksploatacji wie¬ lowarstwowej poczawszy od warstwy przystropo- wej.Obecnie przy prowadzeniu eksploatacji grubych pokladów na zawal ze sztucznym stropem sciane prowadzi sie z podluznym kierunkiem wybiegu w stosunku do rozciaglosci.Wada tego systemu jest ograniczony zakres mo¬ zliwosci stosowania tylko do pokladów o minimal¬ nych nachyleniach i stosunkowo dobrych stropach, poniewaz w przypadku prostego przeniesienia zna¬ nego sposobu okazywalo sie, ze w systemie po¬ przecznym szczególnie przy wiekszych upadach na¬ potykano na duze trudnosci z utrzymaniem frontu sciany, poniewaz calizna miala tendencje do od¬ spajania sie, co stanowilo powazne zagrozenie dla zalogi oraz co utrudnialo mechanizacje urabiania.Dodatkowym utrudnieniem bylo zsuwanie sie prze¬ nosnika w kierunku upadu oraz zalamywanie sie sztucznego stropu w miejscach jego zmniejszonej wytrzymalosci.Celem wynalazku jest opracowanie sposobu eks- 10 20 ploatacji, który eliminujac wady znanych sposobów umozliwialby prowadzenie eksploatacji grubych pokladów ze sztucznym stropem o wiekszym nachy¬ leniu systemem poprzecznym.Cel ten osiagnieto przez opracowanie sposobu, którego istota jest to, ze front sciany sytuuje sie ukosnie do rozciaglosci i do upadu przy czym do upadu w granicach od 80° dc* 75° tak azeby ze wzmocnieniami sztucznego stropu front sciany two¬ rzyl kat ostry, przy czym belkowe wzmocnienia sztucznego stropu ukladane sa w choinke. PL PLPriority: Application announced: May 30, 1973 Patent description was published: April 17, 1975 75,930 KI. 5b, 41/00 MKP E21c 41/00 [CERTIFICATE of the Patent Office falUnl fennmrtliU) it ,,,,, 1 Inventors: Zbigniew Klonowski, Franciszek Rakowski Authorized by a temporary patent: "Miechowice" Coal Mine, Bytom (Poland) The subject of the invention is a method of carrying out the exploitation with the wall system for collapsing thick decks, especially in multi-layer exploitation, starting from the roof layer. At present, when exploiting thick decks, the walls are collapsed with an artificial ceiling. The disadvantage of this system is the limited scope of its applicability only for decks with minimal slopes and relatively good roofs, because in the case of a simple transfer of the known method it turned out that in the cross system especially in the case of major falls, great difficulties were encountered in keeping up I faced the front of the wall, because the entire wall tended to break apart, which posed a serious threat to the crew and hindered the mechanization of mining. An additional difficulty was the slipping of the conveyor towards the fall and the collapse of the artificial ceiling in places of its reduced strength. is to develop an exploitation method which, by eliminating the disadvantages of known methods, would enable the exploitation of thick decks with an artificial roof with a greater inclination in the transverse system. This goal was achieved by developing a method whose essence is that the front wall is situated diagonally to the extension and to a drop, with a drop in the range of 80 ° dc * 75 ° so that the front wall forms an acute angle with the reinforcements of the artificial ceiling, the beam reinforcements of the artificial ceiling being arranged in a Christmas tree.

Zastrzezenie patentowe Sposób eksploatacji grubych pokladów na war¬ stwy systemem scianowym ze sztucznym stropem, znamienny tym, ze front sciany prowadzi sie ukos¬ nie do rozciaglosci i do upadu przy czym do upa¬ du korzystnie w granicach od 80° do 75° tak, azeby ze wzmocnieniami sztucznego stropu, które stano¬ wia znane belki, front sciany tworzyl kat ostry w granicach od 20° do 30° przy czym belkowe wzmocnienia sztucznego stropu ukladane sa w choinke. 75 930 PL PL1. Patent claim A method of exploiting thick decks on layers with a wall system with an artificial ceiling, characterized in that the front of the wall is led obliquely to extension and to a fall, with a fall preferably in the range from 80 ° to 75 °. In order with the reinforcements of the artificial ceiling, which are known beams, the front of the wall forms an acute angle in the range from 20 ° to 30 °, with the beam reinforcements of the artificial ceiling being arranged in a Christmas tree. 75 930 PL PL
