GAS-MONITORING AND SAFETY DEVICE IN AN UNDERGROUND-MINING ROUTE NETWORK
The invention relates to a gas-monitoring and safety device in an underground-mining route network (1), which senses the entire route network. Each person (3) starting off is equipped with a gas radio device (2) and a staff radio device (4). In the region of each entrance (6) and each exit of the route network and in each offshoot of each branch (7) of a route or of each shaft within the route network, stationary cabinets (5) having radio transmitters and radio signal receivers are mounted for the transmission of the staff data and the measured gas data as signals. The data are transmitted to a central monitoring device (9) for evaluation.
Method for operating a mining machine for coal mining in the underground coal face of a coal mine. The plurality of timbering and walling units (1-18) in longwall face length as well as the cutting machine (21), which can be moved along the coal impact, are automatically or semi-automatically controlled so that the setpoint cross section is determined as drive-through model (38) of the required transit cross-section, which the mining machine requires, for each face cross section along the route of the mining machine and stored in the memory of the face control device. The actual passage cross section is determined in each face cross-section and, including the reference points of the measurement, is superimposed in the face control device to the stored drive-through model. The face control device transmits a signal, which is processable in the sense of the movement clearance, to the operating control of the mining machine as a function thereof that the stored drive-through model fits into the determined actual cross-section without excess at the reference points of the measurement. In addition, condition variables are determined which are not taken into account in the drive-through model. The drive-through model is defined by the contour (contour model) which circumscribes the required passage cross-section as a contour or as a surface. Electronic cameras (36) can serve to detect the actual image data, which are suspended in certain intervals along the face.

The invention relates to a hydraulic circuit for the longwall support in underground mining for supporting a longwall by means of a plurality of support shields, which hydraulic circuit comprises a pressure sensor (19) in the annular piston line (10) of each cylinder/piston unit (4). When a predetermined maximum pressure is reached, the pressure sensor (19) emits a pressure warning signal (28), by which the entire longwall can be depressurized by means of a longwall cut-off valve (11). The pressure warning signal (28) is locked with respect to any control signal for one of the hydraulic valves.
A known metering system for automatically maintaining a predefinable concentration of a liquid corrosion inhibitor in the aqueous hydraulic liquid of a water-hydraulic hydraulic system is characterized in that the measuring circuit can be disconnected from the hydraulic system (controllable valves 14, 15), in that the measuring circuit can be short-circuited between the outlet line and the inlet line by means of controllable valves 16, 17 and can be connected to a source (cleaning tank 18) of a cleaning liquid for a cleaning circuit. As a result, a cleaning liquid for cleaning the concentration sensor can be circulated in the measuring circuit for a predefinable time. For the purpose of calibration, the metering system can be charged with a reference liquid with a known inhibitor concentration, in particular water, in particular water from the public supply. Further sensors (23-25) can be connected into the measuring circuit.
A hydraulic circuit for longwall support for use in underground mining for supporting a longwall by means of a plurality of support shields incorporates a pressure monitoring device in the pressure line between the load maintaining valve and the shield control valve. The pressure monitoring device can be a device for monitoring the piston position of the shield control valve which device signals a deviation of the set position predetermined by the shield control device from the measured actual position of the piston of the shield control valve in the form of a deviation signal. It may also be a pressure sensor which signals the deviation of the set pressure predetermined by the shield control device from the measured actual pressure in the form of a deviation signal. Signaling can be acoustic or optical.

CONTROL DEVICE FOR AN EXTRACTING UNIT IN THE WORK FACE OF A MINE
The invention relates to a control device for an extracting unit in the face of a mine, for actuating the hydraulic actuator in the sense of drawing, stepping, setting, and having a plurality of main valves for connecting the actuator of the extracting unit to a main pressure line and a main return line, and a similar plurality of pilot valves, each associated with a main valve for adjusting same and connected to the main pressure line via a pilot pressure line common to all pilot valves and connected to the main return line via a return line common to the main valves and the pilot valves. The pilot pressure line (13) can be shut off and the return line (9) can be blocked off from the main return line (5) and connected to a measuring device (20) for measuring escaping hydraulic fluid. By selectively blocking off or unblocking the pilot pressure line (13), the inner leak rate of the valve block can be determined separately for the main valves and the pilot valves. The measuring device (20) can be a flow rate meter or other flow meter disposed in a bypass. By setting a check valve (22) in the bypass, the return line (9) is permeated only when a limit pressure is exceeded, but the bypass is always permeated, even when the pressure line is blocked off.

A complete screen control device (partial screen control device 10.1 to 10.4) encompassing the program for controlling the partial screen is allocated to each partial screen. The data is retrieved from the data collecting memory and distributed to the partial screen control devices by means of a data collector and a joint master control device in order to be displayed on at least one of the partial screens according to a pattern that can be entered using a keypad.
The invention relates to a stope supporting structure for face support in mines, wherein in order to actuate the hydraulic cylinders for carrying out the removal functions, an operating pressure is applied to an operating pressure line lain in the coal face. A pressure increasing pump (6) in the form of a differential cylinder (7) comprising a differential piston (8) is inserted between the main valve and the working chamber of the hydraulic cylinder (7), parallel to the pressure line. The small piston surface of the pump piston in the differential cylinder forms a pump chamber which is connected to the pressure line leading to the working chamber of the hydraulic cylinder by means of a return valve opening in the outlet direction of the pump chamber. An impulse-actuated reversing valve (19) controlled by the differential piston (8) is provided in order to recurrently apply the operating pressure to the working chamber.

A plug contact pairing comprising a cylindrical plug pot (1) which is permanently fitted in the machine housing, and a cylindrical plug head (2), which has a rectangular external cross section which is congruent with the internal cross section of the plug pot, forms a sealing seam, which is sealed and closed by a sealing ring, between the front circumferential edge (5) of the plug housing (3) and the rim (4) of the plug pot, when the plug contact pairing is in the closed state. The sealing ring (6) is an O-ring (6) which rests closely elastically on the rectangular external cross section of the plug head and a part of its profile is inserted into notches (7) which are incorporated in the side edges (8) of the plug head, at cross-sectional level of the sealing seam.
A plug contact pairing comprises a plug pot (1) with contact pins (31), as well as a plug head (2) with contact circuits (32) for connection of electrical line ends (25, 26). A profiled ring (securing ring) is used to mount the plug head in an interlocking manner in the plug pot, is incorporated with a part of its cross section in a circumferential groove in the plug head and, during closure of the plug contact pairing, latches with the rest of its cross section into a groove on the internal circumference of the plug pot. By virtue of the shape and material of the securing ring and the slot shape, the plug head (2) can be pulled out of the plug pot (1) only with a tensile force which is greater than the limit value. In one development, the plug head (2) is mounted with an identical connection in the plug housing (3), in which case the mounting ring connection is designed in comparison to the securing ring connection such that the tensile force with which the plug head can be pulled out of the plug pot is less than that by means of which the plug head is held in the plug housing by the mounting ring connection.
The shield control device of a longwall shield for carrying out the longwall functions of the longwall shield in the longwall face working in a mine is associated with a distributing device upstream of a group of functional elements. Each of the functional elements of the longwall shield is associated with an exclusive address code word, on the call of which the internal connection between the shield control device and the functional elements depends. The distributing device is arranged in close proximity to the functional elements. The functional elements are valves or sensors.
