摘要： A longwall support control for controlling the movements of longwall support units in the longwall of a mine that includes a central control system and a plurality of control units, of which a separate control unit (mining shield control device) is locally and operationally associated to each longwall support unit. Each mining shield control device comprises a switching element, which permits separating the bus line or lines in the mining shield control device. The mining control devices may also include signal amplifiers. An identical second bus line (parallel bus) permits retransmitting to the adjacent mining shield control device, incoming signals that do not store a code word assigned to the respectively addressed mining shield control device.

摘要： A pilot operated check valve is provided for use in controlling the hydraulic leg 14 of a hydraulic mine roof support, the valve having means 23 to connect a leg extension port 18 to a return port 17 within the valve, when the valve is used to lower the leg 14. This provides more rapid operation than with prior art arrangements in which released pressure from the leg has to return from an extension port back to a remote spool valve controlling leg extension before reaching a return line.

摘要： A mine roof support comprises a canopy, a base section, hydraulic props for raising and lowering the canopy relative to the base section, a hydraulic valve for supplying hydraulic fluid under pressure to the props via a check valve, and a yield valve connected across the check valve. The yield valve has a valve member movable between a first position in which it co-operates with a valve seat to prevent the release of fluid from the props via the yield valve and a second position in which fluid can be released from the props via the yield valve. One side of the valve member is subjected to fluid pressure downstream of the check valve to urge the valve member towards its second position and the other side of the valve member is acted upon by a spring device to urge the valve member towards its first position. The other side of the valve member and the spring device are also subjected to fluid pressure upstream of the check valve so that more and more of the spring force applied by the spring device is substituted by hydraulic force applied to the other side of the valve member by fluid pressure upstream of the check valve as the latter increases until the fluid pressure acting on the spring device balances the urging force thereof at a nominal yield pressure of the yield valve.

摘要： An arrangement for supervising and controlling synchronous displacement of respective pistons of two cylinder-and-piston units, especially of an advancement and a roof cap displacement unit of a roof support assembly for use in underground mining, comprises first and second conduit systems each having two branches each connected with one of the piston and annular spaces of a different one of the units; a switching valve interposed between pressure and a return conduits and the first and second conduit systems; and first and second shut-off valves respectively interposed in those of the branches of the first and second conduit systems which lead to the piston spaces. Measurement devices measure the extent of displacement of each of the pistons, and a control and regulating arrangement determines from the outputs of the measurement devices which of the piston leads the other and causes that of the first and second shut-off valves which is associated with the leading piston to temporarily close and thus discontinue the action of the pressure differential on the leading piston until synchronism in the displacement of the two pistons is restored.
