Abstract
Sposób eksploatacji pokładów węgla z wypuszczaniem węgla znad wyrobiska (podbierkowy) charakteryzuje się tym, że drążenie wyrobiska, wcinkę (zabierkę) wykonuje się znanym sposobem z wykorzystaniem kombajnu chodnikowego (1). Następnie po zakończeniu drążenia zabierki w znany sposób skraca się lub wycofuje podajnik (2) za kombajnem chodnikowym (1). Dalej przystępuje się do demontażu kilku kolejnych odrzwi obudowy (3) z wykorzystaniem manipulatora (1.1), będącego integralną częścią kombajnu chodnikowego (1). Teraz znanym sposobem wycofuje się sam kombajn chodnikowy (1). Dalej, w razie konieczności, wykonywane są wiertarkami (4) zasilanymi z agregatów kombajnu chodnikowego (1) i/lub wiertnicami (5) będącymi na wyposażeniu tegoż kombajnu otwory strzałowe w stropie i ociosach wyrobiska i urabia się znanym sposobem za pomocą materiału wybuchowego węgiel nad wyrobiskiem (tzw. wypuszczanie węgla), który stacza się do przodka. Po wypuszczeniu węgla następuje jego ładowanie na kombajnowy przenośnik zgrzebłowy (1.2) przy pomocy organu urabiającego (1.3) kombajnu chodnikowego (1) i ładowarki (1.4) łapowej lub gwiazdowej, przy jednoczesnym kruszeniu nadwymiarowych brył urobku organem roboczym (1.3) kombajnu chodnikowego (1). Następnie wykonuje się nowe otwory strzałowe wiertarkami (4) zasilanymi z agregatów kombajnu chodnikowego (1) i/lub wiertnicami (5) będącymi na wyposażeniu tegoż kombajnu oraz kolejny cykl wypuszczania węgla - podbierania. Cały system techniczny w obu fazach (faza drążenia wcinki i faza wybierania metodą podbierkową) pozostaje taki sam, włącznie z systemem wentylacji i odpylania powietrza.The method of exploitation of coal seams with the release of coal from above the excavation (pickup) is characterized by the fact that excavation, indentation (take-up) is carried out using a known method using a roadheader (1). Then, after completing the drill, the feeder (2) behind the roadheader (1) is shortened or retracted in a known manner. Then proceed to disassembly of several successive housing frames (3) using the manipulator (1.1), which is an integral part of the roadheader (1). Now the roadheader itself is being withdrawn in a known way (1). Then, if necessary, they are made with drills (4) fed from aggregates of a roadheader (1) and / or drills (5) which are equipped with this combine harvester, boreholes in the ceiling and side walls of the excavation, and using a known method of blasting coal over excavation (so-called carbon release), which rolls down to the ancestor. After the coal is released, it is loaded onto the combine scraper conveyor (1.2) with the help of a digging unit (1.3) roadheader (1) and a foot or star loader (1.4), while crushing oversized spoil lumps with the working organ (1.3) of the roadheader (1) . Then new bore holes are made with drills (4) fed from aggregates of the roadheader (1) and / or drills (5) equipped with this combine harvester and another cycle of releasing coal - picking up. The entire technical system in both phases (chisel drilling phase and pick-up phase) remains the same, including the ventilation and dust removal system.
