Abstract
Sposób określania wartości poziomej radialnej wektora przyspieszenia Px drgań gruntu dla różnych odległości od źródła drgań wytworzonych poprzez odpalenie ładunku materiału wybuchowego, umieszczonego w rozmieszczonych w linii otworach strzałowych, znajdujący zastosowanie w górnictwie odkrywkowym, w celu określenia czy rozkład drgań parasejsmicznych układa się kołowo, w którym pomiaru poziomej radialnej wektora przyspieszenia Px drgań gruntu dokonuje się w punktach pomiarowych, umieszczonych w różnych odległościach od źródła drgań i pod różnymi kątami kierunkowymi ?, z których każdy stanowi kąt pomiędzy linią otworów strzałowych a linią łączącą punkt pomiarowy ze źródłem drgań, które stanowi środkowy otwór strzałowy lub środek linii otworów strzałowych charakteryzuje się tym, że wybiera się od kilku do kilkunastu punktów pomiarowych, dla których kąt kierunkowy ? jest z przedziału od 0° do 90° i mierzy się ich rzeczywistą odległość R od źródła drgań, kolejno wyznacza się wartość średnią tych odległości S, a następnie rzeczywistą odległość R poszczególnych punktów pomiarowych od źródła drgań dzieli się przez wartość średnią odległości S, przez co otrzymuje się wskaźnik wpływu odległości RD dla każdego punktu pomiarowego, po czym mnoży się wartość poziomej radialnej wektora przyspieszenia Px drgań gruntu zmierzonej w danym punkcie pomiarowym przez odpowiadający danemu punktowi pomiarowemu wskaźnik wpływu odległości RD, a wyniki otrzymane dla wartości średniej odległości S punktów pomiarowych od źródła drgań, dla wybranych od kilku do kilkunastu punktów pomiarowych, dla których kąt kierunkowy ? wynosi od 0° do 90°, nanosi się na układ współrzędnych i przedstawia się graficznie przy pomocy wykresu Px=f(?) poziomej radialnej wektora przyspieszenia drgań, z którego odczytuje się następnie, czy rozkład drgań parasejsmicznych układa się kołowo.The method of determining the horizontal radial value of the acceleration vector Px of ground vibrations for different distances from the source of vibrations generated by firing explosive charges placed in line of blast holes, used in opencast mining, in order to determine whether the distribution of paraseismic vibrations is circularly in which the measurement of the horizontal radial acceleration vector Px of ground vibrations is made at measuring points, located at different distances from the source of vibrations and at different directional angles?, each of which is the angle between the line of shot holes and the line connecting the measuring point with the source of vibrations, which is the central hole blasting or the center of the blast hole line is characterized by the fact that from several to several measuring points are selected, for which the directional angle? is from 0 ° to 90 ° and their actual distance R from the source of vibration is measured, the average value of these distances S is determined successively, and then the actual distance R of individual measuring points from the source of vibration is divided by the average value of distance S, by which the RD distance influence indicator is obtained for each measuring point, then the value of the horizontal radial acceleration vector Px of the ground vibration measured at a given measuring point is multiplied by the RD distance impact indicator corresponding to a given measuring point, and the results obtained for the mean value of the distance S measuring points from the source vibrations, for selected from several to several measurement points, for which the direction angle? is from 0 ° to 90 °, plotted on the coordinate system and graphically represented by means of the Px = f (?) graph of the radial horizontal acceleration vector, which then reads whether the distribution of paraseismic vibrations is circular.
