Abstract

Opinka (1) dla podziemnych wyrobisk górniczych ma postać kratownicy utworzonej przez proste pręty podłużne (2) i pręty poprzeczne (3) wzajemnie złączone ze sobą. Co najmniej dwa sąsiadujące ze sobą pręty podłużne (2) mają większą średnicę (D') niż średnica (D) pozostałych prętów podłużnych (2), a odległość pomiędzy tymi prętami (2') wynosi co najwyżej 0,6 odległości pomiędzy pozostałymi prętami podłużnymi (2). Pręty podłużne (2') o większej średnicy (D') są prętami skrajnymi opinki (1). Pręty poprzeczne (3) na swych końcach przeciwnych do skrajnych prętów podłużnych (2') o większej średnicy (D') są wydłużone.The lacing (1) for underground mining excavations has the form of a lattice formed by straight longitudinal bars (2) and transverse bars (3) interconnected with each other. At least two adjacent longitudinal bars (2) have a larger diameter (D') than the diameter (D) of the other longitudinal bars (2), and the distance between these bars (2') is at most 0.6 of the distance between the remaining longitudinal bars (2). Longitudinal bars (2') with a larger diameter (D') are the end bars of the lagging (1). The transverse bars (3) at their ends opposite to the extreme longitudinal bars (2') of larger diameter (D') are elongated.
