Abstract
In a method for milling an opencast mining surface or for milling off layers of an asphalt or concrete traffic surface with a milling machine removing the ground surface, by milling the ground surface along a predetermined milling track having a predetermined length, by transporting the milled material via a conveying device to at least one container of a truck that travels along next to the milling machine, said truck having a predetermined maximum loading volume per load, and by replacing a fully loaded truck with an unloaded truck when the maximum loading volume of a truck load has been reached, it is provided for the following features to be achieved: calculation of the maximum total loading volume resulting over the length of the current milling track as a function of the current effective working width and a milling depth that has been optimized in relation to a predetermined, preferably maximum milling power, calculation of the number of truck loads required for the maximum total loading volume of a milling track, determination of an effective total loading volume of the current milling track, which results from the volume of the nearest whole number of loads, and adjustment…
