摘要： A coal cutting machine 13, a conveyor 12 and a plurality of mine roof supports 10 extend along the face 11 of a coal mine. The operation of the hydraulic jacks of the roof supports are controlled by pilot valves which are electrically powered and rotationally driven. For example, motorized or cam operated pilot valves can be used. Such pilot valves use much less energy than valves controlled conventionally by solenoids, and the electricity supply can thus be at an intrinsically safe level.The operation of the pilot valves include unitary operation of a given support, remote operation of one support from another and sequential operation of a series of supports. When the system controls a plurality of supports sequentially, sensing means sensitive to a first pressure level in a first support when the first support is set to a mine roof activate another support in the sequence when the first pressure level has been sensed in the first support, while continuing the raising of the pressure in the first support until a second, higher pressure level is detected.A group of supports is controlled by a control station positioned at a face end, and in addition each support has its own individual control position. The control station incorporates a microprocessor which may be reprogrammed underground.

摘要： A self-advancing mine roof support is provided, in addition to the normal manually operable control valve means for controlling raising and lowering of the roof-engaging structure of the support and operation of the advancing means, with an automatic sequence control valve means operable in response to a control signal from a position removed from the support, for example from an adjacent support, and an isolating valve means arranged so that control of the various operations can be effected either by means of the manually operable means or from the safety of a location spaced away from the support being controlled by means of the automatic valve means each independently of the other.

摘要： An underground support, e.g. for the roof of a mine, has a roof engaging canopy 10 which can be raised and lowered in a controlled manner by hydraulic legs 14. Inflatable flexible membrane means, for example in the form of bags 12, are provided on the upper face of the canopy 10, which shape themselves to the mine roof and distribute loading evenly thereto. Inflatable flexible membrane means may also be used to prevent flushing of loose debris between adjacent supports, and on roadway supports.

摘要： Attachment means are provided for attaching a mine roof support to an abutment, (e.g. a flexible conveyor) the attachment means comprising a ram arrangement in the form of at least two rams 25, 26 operable to effect relative movement between the mine roof support and the abutment. The provision of two or more rams instead of the conventional single ram means that smaller bore rams may be used, for example a 60 mm bore as opposed to 41/4 inch bore and this makes it possible to cover or encase the rams in a protective shield without reducing the vertical space available to a miner underneath the mine roof support.
