摘要： A water spray system particularly, but no exclusively, for mineral mining, comprising a pick (1) having an integral shank (4) by which it is releasably receivable in an aperture (17) of a block (16), a heel (7) extending rearwardly from the pick (1), a hole (9) passing through the heel (7) and a pair of spaced-apart cheeks extending beyond the hole, a spray nozzle (24) received in a bore (22) of the block (16) with a head (25) of the nozzle projection above an upper surface of the block (16) to a location between the cheeks (8), with a water discharge orifice of the head (25) so located beneath the heel (7) and with respect to the through hole (9) of the heel (7) that water discharged from the orifice into the through hole and exiting the through hole induces an air flow wholly or partially through the through hole. Other aspects of the invention are the pick (1), the block (6), a releasable latching system, and a drivable member.

摘要： A system for extraction of a mineral cutter pick (1), and optionally any interposed sleeve (19), the pick (1 ) comprises an elongate shank (4) extending from an enlarged head (2), has a piston (12) coaxial with the shank (4), with one end face (16) of the piston (12) subjectable to hydraulic pressure fluid, and with another, opposite end face (15) of the piston (12) capable of engaging an end face (5) of the shank (4), a sealing ring (14) to prevent passage of hydraulic fluid being carried by the piston (12), whereby axial movement of the piston (12), under hydraulic pressure, in turn axially displaces the pick (1 ), whilst further movement of the piston (12) results in extraction, if required, of sleeve (19).

摘要： A mineral cutting device comprising a plurality of replaceable picks (10, 10A - 10G) and associated water conveying lances (20, 20A- 20G), each lance being tubular and having a hollow, water-conveying interior and being contained, at least partially, within a bore (13, 13A, 13B) in the pick (10, 10A - 10G) when the pick (10, 10A - 10G) has been mounted on the device (1, 1A, 1B), and each lance (20, 20A- 20G) terminating at or adjacent the end of the bore, at a water discharge orifice (23).
The invention also includes a lance for use with the mineral cutting device defined above, the lance (20, 20A - 20G) comprising an elongate, tubular member having a hollow, water-conveying interior, one end of the lance being connected in a water sealing manner to a mounting adaptor (18, 18A - 18F) by which the lance (20, 20A- 20G) is, in use, releasably mounted on a portion of the cutting device in fluid flow communication with a supply source of pressurised water, the adaptor (18, 18A - 18F) also being in fluid flow communication with the hollow interior of the lance.
The invention also includes a mineral cutter pick comprising a head (9, 9A, 9B), an integral shank (12, 12A- 12D) formed integrally with the head (9, 9A. 98) and a bore (13, 13A, 13B) extending along at least portions of both the head (9, 9A, 9B) and the shank (12, 12A - 12D), the shank bore (13B) being formed at least partially in a side (27) of the shank (12, 12A - 12D), which, in use, is the compressive stress side.
In another embodiment, a mineral cutter pick comprises a head (9, 9A, 98) provided with a hard material cutting tip (11), and a shank (12, 12A- 12D) formed integrally with the head, a bore (13, 13A) provided along at least the pick head (9, 9A, 98), with an outer bore end (14) located rearwardly of the cutting tip (11 and an inner bore end (15) intersected by a slot (42) provided in at least a portion of the shank (12D).
