While the screen display is suitable only for image display, which although may contain excerpts and flows from other images, but it is not inthis regard is already full. Moreover, exposure and flows must be pre-programmed so that the alignment of current needs and the needs of the current operation is not possible.
Under the image within this application is defined as any display on the screen display device that is useful or desirable for the management or control of the installation, whether actual stationary or moving image installations or parts of installations, a graphical representation, a schematic diagram or view charts of functions and processes, displaying commands and command sequences, operational parameters and settings as a separate data series and data tables. The content and type of graphic representations is determined only by the design of the setup used by the sensors and recording devices and the flow of data to a computing device for managing production processes and from the computing device to control manufacturing processes.
The objective of the invention is to improve the installation of the above purpose, therefore, to provide a simultaneous display of multiple images in parallel to each other and with any change and an arbitrary sequence next to each other and without cooperation the many influences and blending.
The problem is solved due to the fact that with the computing device installation correlated (linked) data storage device intended for information and data collection, which can be shown on-screen display device, and is equipped with a storage device for storing the collected data, which are formed in the installation or part installation and include commands, dimension value, the captured images, the operational parameters of shields and/or fixing the functions performed by each of the shields, and the screen display contains several independent and separated from each partial screen display devices, each of which correlated finished control device, which is independent from the other control devices of the partial screen display devices and which is equipped independent of other program, with the computing device, the installation is made with the possibility of requesting the specified data from the data storage and distribution of these data for the partial on-screen display devices according to the input image through the control of a master device that is powered and programmed (parameterisable) connected with it through the keyboard on the desire of the operator so that the definition is stored by the command, dimension value, the captured images or operational parameters are selected by the operator for retrieving from the data storage and distribution for rendering on one or more partial screen display devices, selected by the operator, and the rest of the requested data selected by the operator, shall be distributed to one or more other partial screen display device in the image (the scheme), type(th) operator through the keyboard.
When carrying out the invention one operator is able to keep control of several critical elements, such as areas of the face, features or parameters (measurement results); to collect and store data related to these critical elements, as in the past period of time, and in real time; randomly choose several, for example four, of the specified element, which simultaneously and in parallel visualized, i.e. displayed on the screen, with no impact on each other and not overlapping each other, and the other elements can be any programmable sequence. These four elements can be current operational parameter extraction machine operating parameter extraction machine in the past, the image of the shields, to which the mining machine at the moment at the result, and the image of the shields, which the mining machine just passed.
Thus, the operator of several independent partial on-screen display devices can display a subset of information elements from a larger set, which greatly increases the reliability and efficiency of the management of downhole equipment.

The data on the drive data of the master computing device (control master device) distributes on the computing device, display control device, a partial display device) according to the specified input device settings. The input device may be a storage device that contains the program for distribution of images. First of all, we are talking about the keyboard, which has the advantage that it can be used at any time to choose the content, way before the delivery and the necessary partial screen display device. Multiple displays (partial screen display devices), located, for example, according to scheme 2×2 or 2+3, can be located in the same plane in the cover of the housing of the computing device and is visible from the outside.

SUBSTANCE: system composed of hydraulic units for underground mining operations is intended for, particularly, underground working supports, actuators and/or pickups, all of them being encased and interconnected or can be connected, via a data transfer system, to the control unit. Note that every actuator is designed to make every hydraulic unit function operate and/or every pickup is set up to read out the hydraulic conditions at the point of measuring whatever quantity of the walking support. Mind that every actuator (3) and/or sensitive element (7, 8) in its casing (4; 18, 19) are wired to readout unit (20; 30), while hydraulic unit (1) for every function (2) or every point of measurement is connected to data element (12; 13) connected in the circuit to allow a readout unit with a receiver and/or transmitted module (20; 30) to effect a contactless inductive data readout therefrom and to transmit the said data to control unit (6). Data element (12; 13) represents a transponder or a transmitter incorporating a receiver coil. The control unit (6) uses this data via the data transfer system to allow an automatic single-valued identification and reprogramming.
EFFECT: faultless connections.

SUBSTANCE: method for extraction and underground use of coal includes cleaning extraction and dumping of coal, fixing and controlling ceiling and transporting coal along face to drift. On the drift, in moveable generator, coal is pulverized for intensive burning with use of jets in water boiler firebox, where high temperature of steam is achieved (about 1400 C°), enough for decomposition of water on oxygen and hydrogen. These are separated, then oxygen is fed back to jets, and hydrogen is outputted along pipes and hoses in drifts and shaft. Variants of underground generator for realization of this method are provided. Also provided is method for extraction of disturbed coal beds by short faces. It includes extraction and dumping of coal on face conveyor, fixing of ceiling behind combine, moving conveyor line and support sections in direction of cleaning face displacement, control of ceiling with destruction and partial filling. Extraction of coal is performed in short curvilinear faces by long stripes along bed, in straight drive without forwarding drifts, with preservation and reuse of ventilation and conveyor drifts, equipped with mounting manipulator robots, with fixing behind combine by automatically operating support deflectors without unloading and displacing sections in area of coal extraction. Extraction and transporting of coal is performed by fast one-drum combine and curvilinear reloading conveyor, supplying coal to drift conveyor or immediately to underground gas or energy generator placed immediately on drift. Also proposed is face scraper conveyor for realization of said method, wherein pans are made with step along front face profile, greater, than along back one, while forming common line curved towards face with constant curvature. Also proposed is a method for controlling complex for unmanned coal extraction.
EFFECT: higher efficiency, effectiveness, broader functional capabilities.
