    摘要: A hydraulic circuit for longwall support for use in underground mining for supporting a longwall by means of a plurality of support shields comprises in the annular piston line of each cylinder/piston unit a pressure sensor. Said pressure sensor upon reaching a predetermined maximum pressure activates a pressure deviation signal, which causes the entire longwall to be depressurized by means of a longwall shut-off valve. The pressure deviation signal is blocked for one of the hydraulic valves against each triggering signal.

    摘要: The invention relates to a plug-type coupling for sheathed electrical cables, particularly for use in mining, with a flexible protective sheath which accommodates electrical conductors of the cable. The end of the sheath is gripped in a pullproof and sealed fashion between a pressed sleeve which surrounds it and an inner backing sleeve, these parts forming part of the coupling which also includes a coupling sleeve which adjoins the pressed sleeve and receives an insert which holds contact elements electrically connected to the electrical conductors. According to the invention, the pressed sleeve is joined to the coupling sleeve to form a one-piece connector to which the insert carrying the contact elements can be coupled in a pullproof fashion by means of a snap connection. The distinctive features of the sheathed cable coupling according to the invention are simplicity of construction, ease of assembly and low production cost.

    摘要: A method for determining the active power (P) of asynchronous electric motors of winning and conveying equipment in underground mining. According to the invention, particularly easy and accurate determination of the instantaneous active power of the motors is obtained by storing the individual motor characteristic (P(n); M(n)) of each motor in a computer, by detecting the instantaneous speed (n, n') of the motor with the aid of a tachometer and by comparing this speed with the characteristic stored in the computer, the active power being derived from the torque value or power value assigned to the detected instantaneous speed, as stored in the computer. This particularly rapid and simple calculation of the power value does not require any readings to be taken at the power supply to the motors.

    摘要: 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.

    摘要: A safety device which detects personnel data of persons located in the detection zone thereof, said safety device operating continuously or in regular cycles and reporting to the central controller. The personnel data of all persons located in the longwall mine are stored in a central storage device of the central control and constantly compared to the detected personnel data. If a discrepancy arises between the saved personnel data and the detected personnel data, the central control unit executes a command which halts all functions of the excavation devices and interrupts all moving functions, said command being directed at the switching devices of the associated excavation devices.

The controller utilizes a central unit with a microprocessor and assigned, programmable memory devices for the storage and processing of software as well as a connector unit with connectors or circuits for communication between the controller and other controllers and/or actuators, sensors or the like, that are to be controlled with the controller. Both the central unit and the connector unit utilize a modular design. A collection of modules with different performances and/or functionalities are provided for both the central unit and the connector unit to form the hardware of a controller. The modules can be combined with one another and coupled together according to a modular concept.
