Description
Nastepnie wierci sie dlugie otwory 3 dwustronnie z obu stron przodka do polowy jego dlugosci, od strony chodników odstawczych 4 i zaladowuje ladunkiem rozczlonkowanym.Odleglosc pierwszego szeregu otworów od podsadzonego^ czola przodka i odleglosc nastepnych szeregów otworów miedzy soba zaklada sie zgodnie z obliczona w metryce strzalowej siatka wiercen. Sumaryczny zabiór (postep przodka przy jednym strzelaniu) przyjmuje sie dowolny wedlug potrzeb technologii i robót górniczych, lecz nie wiekszy niz dopuszczalna wielkosc odsloniecia stropu. Otwory odpala sie przy pomocy zapalników milizwlocznych stosuac kombinaqe zwlok w ladunkach w otworach i w kolejnych szeregach. Zaladunek urobku odbywa sie z dwóch storn przodka przy pomocy ladowarek.Istota strzelania wedlug wynalazku polega na tym, ze odstrzeliwany urobek uzyska przestrzen na niezbedna wielkosc rozluzowania kosztem uscislenia podsadzki hydraulicznej i wypelnienia przestrzeni wyrobisk rozcinkowych na dlugosci sumarycznego zabioru.Sposób wedlug wynalazku umozliwia rezygnacje z budowy tam podsadzkowych na dlugosci czola przodka 2. Ponadto takie urabianie zloza umozliwia prowadzenie bardziej wydajnej organizacji pracy polegajacej z jednej strony na zapewnieniu duzej ilosci urobku pozwalajacej na dlugotrwale wybieranie go i w zwiazku z tym lepsze wykorzystanie maszyn zaladowczych i odstawczych a z drugiej strony na równoczesne podsadzanie wybranej przestrzeni oraz wiercenie i przygotowywanie nastepnego zabioru. PL PLNext, long holes 3 are drilled on both sides of the face to half its length, from the side of holding galleries 4 and loaded with a disassembled load. The distance of the first series of holes from the raised face of the face and the distance of the next series of holes between each other is assumed in accordance with the calculation of the sheet drilling grid. The total take-off (the advance of the face with one shot) is assumed to be any according to the needs of mining technology and works, but not greater than the permissible size of the ceiling exposure. The holes were fired with time-delay detonators and the corpses were combined with charges in the holes and in the following rows. The excavated material is loaded from two sides of the face with the use of loaders. the length of the forehead of the forehead 2. Moreover, such mining of the deposit allows for a more efficient organization of work consisting, on the one hand, in ensuring a large amount of spoil, allowing for its long-term extraction and, therefore, better use of loading and hauling machines, and, on the other hand, for simultaneous filling of the selected space and drilling and preparing the next harvest.
