Abstract

Kaszt górniczy, stosowany w podziemnych zakładach górniczych do podparcia stropu, składa się belek (1, 2, 3), ułożonych w warstwach jedna na drugiej, poprzecznie usytuowanych. Krzyżujące się belki kolejnych warstw w miejscu styku posiadają wręby o długości co najmniej równej szerokości belek, pozwalające na wzajemnie przenikanie się belek na głębokość dostateczną dla uzyskania styku dolnych i górnych powierzchni najbliższych sobie równoległych belek kasztu. Ułożone jedna na drugiej belki tworzą ściany (I, II, III, IV, V) połączone ze sobą w wyniku wzajemnego przenikania belek kolejnych warstw oraz przestrzenie pomiędzy ścianami (I, II, III, IV) oraz (I, II, IV, V) wypełnione ułożonymi w warstwach klockami (4).The mining castle, used in underground mining plants to support the roof, consists of beams (1, 2, 3), arranged in layers on top of each other, transversely located. The intersecting beams of successive layers at the point of contact have notches with a length at least equal to the width of the beams, allowing mutual penetration of the beams to a sufficient depth for the contact of the lower and upper surfaces of the parallel parallel beams of the groove. Stacked beams form walls (I, II, III, IV, V) connected together as a result of mutual penetration of beams of successive layers and spaces between walls (I, II, III, IV) and (I, II, IV, V ) filled with blocks arranged in layers (4).
