    摘要: A hydraulic assembly for a mining system is disclosed. The hydraulic assembly may have at least one control valve for controlling a supply of hydraulic fluid to a hydraulic actuator of the mining system. The hydraulic assembly may also have at least one temperature sensor associated with the at least one control valve. The at least one temperature sensor may be configured to measure a temperature of the at least one control valve. In addition, the hydraulic assembly may have a control unit in communication with the at least one temperature sensor. The control unit may be configured to receive the temperature measured by the at least one temperature sensor. The control unit may also be configured to determine that a leakage has occurred in the at least one control valve based on the temperature.

    摘要: The present invention provides a device useful for supporting underground mine/tunnels. The device continuously monitors the roof load coming over the canopy and correspondingly yielding/convergence indicated by the pointer on graduate scale. The roof load coming on the canopy (9) is transmitted to the prop via a set of steel disc springs (5) to increase the yielding and longevity of the present device. The present invention has mechanism for preloading upto the desired load. It is a simple, easily transportable and user friendly device having quick release mechanism from a safe distance.

    摘要: The support 10 of the present invention resembles a conventional Acrow prop which may be used for temporarily supporting a load. In particular, the present invention is arranged to support a surface at a static position. For example, the surface may comprise a ceiling/beam/lintel within a structure wherein the usual permanent supports for the ceiling/beam/lintel are being replaced or deemed temporarily insufficient. However, the present invention can be used in numerous situations where a support 10 is required and for which the support 10 can be quickly and easily installed. The present invention provides (hydraulic) movement means to move the upper end relative to the lower end. In addition, the present invention provides retraction prevention means to prevent the upper end moving towards the lower end whilst supporting the load and prevents the inner core member 14 being forcibly retracted back into the outer sleeve member 12 due to the compressive force of the load. A hydraulic ram 22 has a maximum extension limit and the present invention uses an adjustable mounting/abutment mechanism which means that a relatively small hydraulic ram 22 can be installed in the outer sleeve member 12. This size of hydraulic ram 22 will then be suitable for all heights and the support is not limited to simply being moveable within a restricted range.

    摘要: An arrangement for erecting a columnar supporting element of a hardenable flowable material, for a roof of an underground excavation, has a hollow casing for filling with a hardenable flowable material and is composed of two telescopable casing portions each composed of two open-end semi-circular sections, an element for holding the upper casing portion in contact with the roof of an underground excavation and arranged adjacent to the casing, and elements for connecting the semi-circular sections of at least the lower prop casing portions with one another so as to be pivotable about a longitudinal pivot axis which is parallel to the longitudinal axis of the prop casing, and locking the same with one another.
