        <p>Высокие скорости проведения траншей необходимы для сокращения сроков строительства и наращивания производственной мощности карьеров. В период нормальной эксплуатации скорость проходки траншей зависит от интенсивности добычи, длины добычного фронта, направления подвигания фронта относительно залегания рудного тела, высоты и числа добычных уступов, находящихся в одновременной отработке, ширины рабочих площадок и других факторов и может определяться по формуле ...</p>

        <p>High trenching speeds are necessary to reduce construction time and increase the production capacity of open pits.During normal operation, the speed of trenching depends on the intensity of mining, the length of the mining front, the direction of front movement in relation to the occurrence of the ore body, the height and number of mining ledges that are in simultaneous mining, the width of working sites and other factors and can be determined by the ...</p>
