Abstract

Sposób wyznaczania wartości wskaźnika wielkości bloku skalnego podczas strzelania milisekundowego urabianego jednym otworem strzałowym załadowanym materiałem wybuchowym MW, mający zastosowanie w górnictwie odkrywkowym do obliczania powstających prędkości drgań, charakteryzuje się tym, że przed strzelaniem dokonuje się pomiaru objętości Vb urabianego jednym otworem bloku skalnego o wysokości H [m], szerokości S [m] i grubości Z [m], przy czym szerokość S to odległość między otworami w szeregu, a grubość Z to odległość od powierzchni urabianej materiałem wybuchowym MW ściany skalnej do osi wypełnionego materiałem wybuchowym MW otworu strzałowego, po czym tak otrzymaną wartość objętości bloku skalnego Vb dzieli się przez standardową objętość laboratoryjnej próbki skalnej Vp o smukłości wynoszącej 3 i wymiarach 5*5*15 cm, przez co otrzymuje się wartość, której pierwiastek kwadratowy jest wskaźnikiem wielkości bloku skalnego WwBS.The method of determining the value of the rock block size index during millisecond blasting mined with one blasting hole loaded with explosive material, applicable in opencast mining to calculate the vibration velocities that occur, is characterized in that before blasting, the volume Vb of a rock block mined with one hole is measured, having a height H [m], width S [m] and thickness Z [m], wherein the width S is the distance between the holes in the row and the thickness Z is the distance from the surface of the rock wall mined with explosive material to the axis of the blasting hole filled with explosive material, after which the value of the rock block volume Vb thus obtained is divided by the standard volume of a laboratory rock sample Vp with a slenderness of 3 and dimensions of 5*5*15 cm, which gives a value whose square root is the rock block size index WwBS.
