摘要： A hydraulic control system, particularly for controlling the operation of roof support props of a mine working, employs control devices operated manually to feed pressure fluid to the working chambers of the props to effect extension or retraction thereof. A two-state valve device is operated when the props are extended to ensure that the correct setting pressure is established. This valve device has a control piston which is actuated to cause the device to establish independent connection between the main fluid pressure line and the associated working chambers of the props charged with fluid by the initial operation of the control devices. The connection established by the valve device is maintained even if the control devices break connection between the chambers and the pressure line. When the correct setting pressure is reached, a further control piston of the valve device is actuated to break the connection established by the valve device ready for the next operative cycle.

摘要： A longwall mineral mining installation has a conveyor and a plurality of roof support units positioned side-by-side on the goaf side of the conveyor. Each roof support unit has a roof shield having an advanceable shield extension. Each unit has a first hydraulic ram for extending its shield extension, and a second hydraulic ram for advancing the conveyor. The extension of each first ram is controlled in dependence upon the retraction of one of the second rams (either the second ram of the same unit or that of an adjacent unit). This control is effected by controlling the supply of pressurized hydraulic fluid to the first rams. In one embodiment this is carried out by a control valve which has a spring-loaded plunger which engages with a series of equispaced cams on the movable cylinder of the associated second ram. In another embodiment, the piston rods of the rams are provided with series of equispaced magnets. The cylinders of the rams are provided with sensors, which sense the magnets and generate control signals. A control box is provided to direct the control signals to control valves associated with the rams, so that the first rams are extended by the same distance as that through which the second rams are retracted.

摘要： A hydraulic control system for use with double-acting shifting rams in a mine working.The system has a pump for supplying pressure fluid and main and return feed lines or conduits connected to the pump and laid along the working. An adjustable pressure-regulating device or devices serves to provide fluid at variable pressure in a further feed line or conduit.Each ram has its working chambers connected to a control device which is in turn connected to the main and further feed lines or conduits and to the return line or conduit. The devices can each be set to various positions to operate the rams in order to extend one of the rams its associated device is set to connect the working chamber used for extension (having the larger piston working surface area) to the further feed line or conduit, and to connect the other working chamber used for retraction (having the smaller piston working surface area) to the to the main feed line or conduit. With the aid of the pressure-regulating device or devices the force of the ram can then be controlled.

摘要： The invention relates to a mine roof support assembly for use in winning mineral material from a mineral mining working having a mineral face. The assembly comprises three roof support units positioned side-by-side along the face, and a goaf shield common to the three units. Each of the roof support units has a roof shield supported on a floor sill. The goaf shield is adjustable in height so as to extend from the floor to the roof of the working. Advance means are provided for advancing the roof support units towards the face, and further advance means are provided for advancing the goaf shield to follow up the advance of the roof support units. The further advance means acts between the goaf shield and the roof support units, and is such as to advance the goaf shield by a distance greater than the distance through which the advance means advances the roof support units.

摘要： Apparatus for controlling the position of a mineral winning machine, such as a plough, movable along a guide at one side of a scraper-chain conveyor employs cantilevered beams extending between the conveyor and roof supports as known per se. Brackets are provided at the goaf side of the conveyor and these brackets are pivotably coupled to the cantilever arms by way of flat pan-like components. Upstanding piston and cylinder units are positioned close to the conveyor goaf side wall preferably within protective walls of the brackets. These units are pivotably connected at their upper ends to the brackets and to extensions of the pan-like components so that the beams are effectively pivotably coupled to the units at positions offset towards the conveyor relative to the pivot connections with the brackets. The space between the conveyor and the supports is relatively unrestricted. The units are extended or retracted to tilt the conveyor and the guide whereby to control the cutting position of the machine.

摘要： The invention relates to an advance mechanism for a roof support assembly constituted by a plurality of roof support units positioned side-by-side along, for example, a longwall face of a mineral mining working. The advance mechanism comprises a pair of hydraulic advance rams and a pair of resilient, generally parallel guide rods. The guide rods are interconnected at one end by means of a head-piece which is attachable to a conveyor extending along the longwall face. The other end of each guide rod is attached to a respective slide piece which is slidably guided on a respective guide rail which is attached to a floor girder of a roof support unit. The hydraulic advance rams are each pivotally attached to one of the slide pieces and to one of said floor girders. The guide rods are provided, adjacent said one end, with outwardly projecting alignment members each of which co-operates with one of said floor girders to align an associated roof support unit during its advance.

摘要： A cutting (winning) machine comprises a frame which is provided with a pair of endless drive tracks. A mast is pivotally mounted on the frame for movement between an upright working position and a non-working position (in which it lies substantially flat on the frame). The frame also supports a platform, which is also pivotal relative thereto in the vertical plane. A carriage is arranged to move along the mast, the carriage supporting a cutting head such as a shearer drum. The mast can be positioned in an upright position at either end of the frame, so that the machine can carry out work in both directions of travel.
