        <p>Задача автоматической максимизации производительности самоходных гидромониторов при разработке каменноугольных пластов гидравлическим способом еще не решена, хотя практикой уже давно установлено, что зависимость между производи­тельностью гидромонитора q и скоростью перемещения его ствола ѵ по фронту забоя имеет экстремальный характер. Как видно из рис. 1, вершина А, характеризующая оптимальный рабочий режим, под воздействием изменения горно-геологических условий дрейфует...</p>

      <abstract xml:lang="en">
        <p>The problem of automatic maximization of self-propelled hydraulic monitors productivity at development of coal seams by hydraulic method has not been solved yet, though practice has long ago established that the dependence between the hydraulic monitor productivity q and the speed of its trunk movement v along the face front has an extreme character. As can be seen from Fig. 1, the top A, which characterizes the optimal operating mode, under the influence of changes in mining and geological conditions drifts...</p>
