The designs of submersible hammers and dampers protected by patents for reducing the vibration of the drilling rig of roller drill machines are proposed. The variants of modernizing drilling rigs for drilling hard rocks and faces of complex structures are considered. Particular attention is paid to the joint work of submersible shockers and pneumatic shock absorbers, the preferred schemes for the arrangement of these devices by drilling rigs are indicated. The results of experimental tests of machines with pneumatic hammers are presented to determine the vibration performance and drilling speeds. The pneumatic hammer allows increasing the speed of drilling process to the intensification of the destruction of the plain face by the shock load and the cleavage of the protrusions of the unevenness of the face, the better fitting of the bit to the face and the release of the blades or the bit pins from the drill bit. The choice of a particular type of damper or shock absorber depends on its design scheme and the possibility of changing the design of the drill string. With the complexity of installing a damping device in the mast (with significant dimensions of shock absorbers and drilling of strong heterogeneous rocks), it is advisable to use a set of tools to reduce hydraulic pulsations in the mains and cylinders of the hydraulic system by installing chokes in the oil plants and pneumatic shock absorbers. It is proposed to use the device for the development of pneumatic hammers by a patent-pending drilling method with a hollow piston filled with magnetically active heavy liquid, which will allow controlling the frequency and size of the shock pulses and partially compensating for the drill string fluctuations arising from the uneven immersion of the bit in the array. It is noted that the proposed solutions increase the drilling speed by an average of 15%.

The article covers the issues of increasing the efficiency of tunneling&cleaning combines “Ural”, widely applied at domestic potash mines. It is pointed out that it is possible to provide rational parameters of the process of destroying potash arrays with cutting tools of the executive bodies of mining combines. This assumption is based on the assessment of the drivers load which will reduce the specific energy consumption for ore extraction and will reduce the number of small unenriched classes in breakage products. The authors substantiate rational regime parameters of the operation of the planetary-disk executive bodies in the Ural combines. A method for automatic control of the tunnel&cleaning combine “Ural” is proposed, which ensures the implementation of the process of destruction of the potash massif with rational cutting parameters on the basis of information on the drivers load.

В статье приведены результаты исследований применения фреймворка автоматического создания алгоритмов машинного обучения (AutoML) для решения задач диагностики и оценки технического состояния электродвигателей, применяемых в широком спектре в горнодобывающей промышленности. Представлена работа и функционирование AutoML Фреймворка – FedotIndustrial, разработанного автором. Предложен в качестве экспериментального и практического применения испытательный стенд, на котором при помощи электродвигателей переменного тока формируются условия изменения нагрузки и величины дефекта в виде несоосности. Выявлено, что более информативной является интерпретация данных в виде годографа Парка и диагностической кривой. Установлено что, при решении задача классификации данных с учителем, формируются разметка данных на классы, образующих в совокупности 6 классов технического состояния электродвигателя. Результаты исследований могут быть полезными при дальнейшей разработке предиктивных систем автоматизации и защиты электромеханического оборудования горнодобывающих предприятий.
