Opis patentowy opublikowano: 30.11.1977 93061 MKP E21c 41/00 Int. Cl.2 E21C 41/00 CZYTELNIA] U-eda Patoatowego Puu it Iw -:i ' i| \jam\ \ Twórcy wynalazku: Henryk Gil, Józef Kazek, Piotr Wrega Uprawniony z patentu: Kopalnia Wegla Kamiennego „Gen. Zawadzki", Dabrowa Górnicza (Polska) Sposób wybierania pokladu lub pokladów w filarach szybowych ukladem frontów prostoliniowych Dziedzina techniki. Wynalazek dotyczy sposobu podziemnego wybierania pokladu lub pokladów mi¬ neralów w filarach szybowych ukladem frontów prostoliniowych.Stan techniki Obecnie znany sposób zabezpie¬ czenia szybu przed wplywami deformacji górotwo¬ ru powstajacych od wybierania pokladów w fila¬ rach polega na przechodzeniu z eksploatacja jedno- skrzydlowa frontem przez rure szybowa lub dwu¬ skrzydlowa frontem rozchodzacym sie równolegle w przeciwnych kierunkach od osi szybu. Takie systemy wybierania powoduja koniecznosc wczes¬ niejszego wybierania kostki pokladu w bezposred¬ nim rejonie szybu i podbudowania tak wybranej przestrzeni obudowa np. kasztami lub wypelnie¬ nia podsadzka.Po przygotowaniu bezposredniego rejonu szybu nastepnie prowadzi sie eksploatacje wg jednego z wyzej podanych sposobów. Przy eksploatacji filaru szybowego z kostka w miare zblizania sie frontem do szybu w górotworze otaczajacym szyb naste¬ puje wzrastajace naprezenie sciskajace, które w górnych partiach szybu nie jest kompensowane przez kostke co doprowadza czesto do uszkodzenia obudowy szybu.Przy eksploatacji dwuskrzydlowej nastepuja w górotworze nadmierne odksztalcenia rozciagajace, które sumuja sie z rozciaganiami wywolanymi kostka; taka sytuacja prowadzi równiez do czestego uszkodzenia szybu.Istota wynalazku. Celem wynalazku jest opraco¬ wanie sposobu eksploatacji pokladu lub pokladów stanowiacych filar szybowy, który zmniejszalby, wielkosc auasistatycznego obciazenia górotworu, nad' obudowa szybowa i pozwalal w sposób bezpieczny wybrac w tym rejonie eksploatowany poklad.Cel ten osiagnieto przez opracowanie sposobu, którego istota polega na tym, ze wybiera sie po¬ klad lub jego warstwe ukladem dwóch frontów prostoliniowych znajdujacych sie po tej samej stronie szybu i majacych ten sam kierunek posu¬ wania sie.Skutki wynalazku. Rozwiazanie powoduje znacz¬ na kompensacje odksztalcen rury szybowej, a tym samym pozwala na lepsze utrzymanie szybu. Po¬ nadto umozliwia znaczna koncentracje wydobycia z filarów szybowych i eliminuje koniecznosc wy¬ konania pracochlonnej kostki przyszybowej.Objasnienie figur. Wynalazek w przykladzie wy¬ konania przedstawiono na rysunkach gdzie f%. 1 pokazuje uklad frontów bez kostki przyszybowej, a fig. 2 rozklad odksztalcen w górotworze wzdSuz rury szybowej.Stosowanie wynalazku. Poklad lub jego warstwe w filarze ochronnym 1 dla szybu s wybiera sie ukladem dwóch prostoliniowych frontów 2 i 3 znajdujacych sie po tej samej stronie szybu s i majacych ten sam kierunek posuwania sie.

Cl.2 E21C 41/00 READING ROOM] Patoat U-ed Puu it Iw -: i 'i | \ jam \ \ Creators of the invention: Henryk Gil, Józef Kazek, Piotr Wrega The holder of the patent: the Coal Mine "Gen. Zawadzki ", Dabrowa Górnicza (Poland) Method of selecting a deck or decks in shaft pillars with the arrangement of rectilinear fronts Technical field. The effects of rock mass deformation resulting from the excavation of the decks in the pillars consist in the transition from single-leaf operation with the front through the shaft or two-leaf with the front extending in parallel in opposite directions from the shaft axis. the deck in the immediate area of the shaft and the foundation of the space selected in such a way, the casing, for example, with chaplets or filling with the filling. After the preparation of the immediate area of the shaft, the operation is carried out according to one of the above methods. that the front to the shaft in the rock mass surrounding the shaft is followed by increasing compressive stress, which in the upper parts of the shaft is not compensated by the ankle, which often leads to damage to the shaft casing. ; this situation also leads to frequent damage to the shaft. Summary of the invention. The aim of the invention is to develop a method of exploitation of the deck or decks constituting the shaft pillar, which would reduce the size of the automatic rock mass load above the shaft support and allow for safe selection of the exploited deck in this area. in that the order or its layer is selected by a system of two rectilinear fronts located on the same side of the shaft and having the same direction of advancement. Effects of the invention. The solution significantly compensates for the deformation of the shaft tube and thus allows better maintenance of the shaft. Moreover, it enables a significant concentration of extraction from shaft pillars and eliminates the necessity of making a labor-intensive glazing block. Explanation of figures. The invention in an embodiment is shown in the figures where f%. 1 shows the arrangement of fronts without pane block, and Fig. 2 shows the distribution of deformations in the rock mass along the shaft pipe. The use of the invention. The deck or its layer in the protection pillar 1 for the shaft s is selected by a system of two rectilinear fronts 2 and 3 located on the same side of the shaft s and having the same advance direction. The amounts of the rock mass deformations 4 coming from the front 2 add up to the rock mass deformations 5; p © - 93 0613 93 061 4 walking from the front 3 achieving significant compensation of vertical deformations 6 of the shaft p.
