Description
Przedmiotem wynalazku jest sposób zabudowy pustek w stropie, powstalych wskutek eksploatacji szczególnie w scianach z zawalowym systemem odbudowy.Obecnie gdy prowadzi sie eksploatacje pokladu, nad którym zalega malo zwiezla skala i gdy nastapi miejscowe wypadniecie kamienia ze stropu, czesto w strefie pomiedzy obudowa a calizna dla dalszego postepu sciany zabudowuje sie tak powstala pustke ukladajac na obudowie kant, który rozpiera sciany pustki, taki sposób zabudowy pustek jest bardzo pracochlonny, a przede wszystkim bardzo niebezpieczny, poniewaz ludzie go wykonujacy pracuja pod odslonietym zruszonym stropem.Celem wynalazku jest opracowanie sposobu zabudowy pustek, który dawal by znaczne korzysci i wieksze bezpieczenstwo ludziom go zabudowujacym oraz mógl byc wykonany w czasie, który nie powodowal by koniecznosci zatrzymywania postepu sciany. Cel ten osiagnieto przez opracowanie sposobu, którego istota polega na tym, ze do powstalej na przyklad w stropie sciany zawalowej pustki wklada sie za obudowe co najmniej jeden pojemnik elastyczny i nastepnie wypelnia sie go sprezonym gazem korzystnie powietrzem lub ciecza tak, azeby rozparl sie o sciany pustki stanowiac dla niej obudowe. PLThe subject of the invention is a method of building voids in the ceiling, formed as a result of exploitation, especially in walls with a collapsing reconstruction system. Currently, when the deck is exploited, over which there is only a small scale and when there is a local fall of stone from the ceiling, often in the zone between the casing and the complete the further progress of the wall is built up in such a way that the void is created by placing a corner on the casing that expands the walls of the void, this way of building the voids is very labor-intensive and, above all, very dangerous, because the people who build it work under an exposed unattended ceiling. which would provide significant benefits and greater safety to the people building it, and could be made in a time that would not require stopping the wall progress. This goal was achieved by developing a method, the essence of which is that at least one flexible container is inserted into the cavity formed in the roof of a wall, for example, behind the casing, and then it is filled with compressed gas, preferably air or liquid, so that it bursts against the walls. voids constituting a housing for it.
