Abstract: A core sampling system comprises at least one hollow drill rod, each drill rod arranged to be connected endwise to an adjacent drill rod so as to define a string of drill rods that define an internal drill rod space for receiving core material during drilling, an annular drill bit connected to a free end of an end most drill rod, and a fluid inlet member arranged such that when the core sampling system drills a hole the fluid inlet member is in fluid communication with an annular space defined between the at least one drill rod and the hole, the annular space in fluid communication with the drill bit and thereby the internal drill rod space. The system also includes a core breaking device arranged to effect fracturing of core material received in the internal drill rod space from surrounding ground material. The fluid inlet member is arranged to receive drilling fluid and to direct the received drilling fluid to the annular space and subsequently to the drill bit and the internal drill rod space, thereby urging fractured core material in the internal drill rod space to move through the internal drill rod space towards the fluid inlet member.

Abstract: A connection device for a core drilling assembly is disclosed, the connection device connectible between a head assembly of a core drilling assembly and an inner tube of the core drilling assembly. The connection device comprises a first connection portion and a second connection portion, and includes a connection mechanism arranged to facilitate engagement of the first and second connection portions with each other and disengagement of the first and second connection portions from each other. The connection mechanism includes at least one locking projection disposed on the first connection portion and at least one corresponding locking path disposed on the second connection portion, the locking path having a locking position such that the first and second connection portions are held together when a locking projection is disposed in the locking position. Each locking projection is engageable with a respective locking path, and the locking path is arranged such that the locking projection is movable through the locking path and receivable in the locking position by moving the first and second connection portions substantially towards each other and rotating the first and second connection portions relative to each other. The connection mechanism also includes a locking member mounted on the first or second connection portion such that rotation of the locking member is restricted, wherein when the locking projection is disposed in the locking position, the locking member is reciprocably movable between a first position wherein the first and second connection portions are restrained from rotating relative to each other and the projection is thereby restrained from moving along at least a portion of the locking path, and a second position wherein the first and second connection portions are not restrained from rotating relative to each other and the projection is able to move along the locking path.

Abstract: A valve system for an inner tube assembly is described. The inner tube assembly is arranged to be used in a drilling system to retrieve a core sample, and is arranged to be insertable into a drill string of the drilling system at a first end of the drill string. The valve system is arranged to be configurable in a first closed configuration, an open configuration, and a second closed configuration. The valve system moves to the first closed configuration when fluid is pumped along an interior region of the drill string towards the inner tube assembly in a direction from the first end of the drill string to the inner tube assembly. The valve system is arranged such that, when in the first closed configuration, a pressure of the fluid increases to facilitate deploying the inner tube assembly towards a second end of the drill string. The valve system moves to the open configuration in response to the inner tube assembly reaching a vicinity of the second end of the drill string and being prevented from moving further towards the second end of the drill string. The valve system is arranged such that, when in the open configuration, fluid can flow to a drill bit located at or near the second end of the drill string. The valve system moves to the second closed configuration when fluid is pumped along the interior region of the drill string towards the inner tube assembly in a direction from the second end of the drill string to the inner tube assembly. The valve system is arranged such that, when in the second closed configuration, the pressure of the fluid increases to facilitate retrieving the inner tube assembly from the vicinity of the second end of the drill string.
