A drill rod for breaking up the edge of a hole comprises a cylindrical body, a buffer and injector nozzles. The drill rod injects air and water through its injector nozzles at the material deposited at the edge of the hole, thus achieving the breaking up thereof without the need to use auxiliary equipment or manual operations. A method for breaking up the edge of a hole is described, including using a rod to break up the edge of a hole, and comprising the stages necessary to perform this operation using a drill.

A drilling apparatus includes a drill and a dust removal pipe for removing dust created in drilling from a proximity to a borehole. The drilling apparatus includes a sampling apparatus for collecting a research sample in the dust removal pipe of the drilling apparatus. The sampling apparatus includes a sampling pipe arrangement, at the end of which there is a sampling pipe, the mouth aperture of which is fitted in the dust removal pipe, element for fixing the sampling pipe arrangement to the dust removal pipe, a suction device for forming suction in the sampling pipe, and a collecting arrangement fixed to the sampling pipe arrangement for separating sampling material from air flowing in the sampling pipe arrangement, and for collecting sampling material. The sampling apparatus includes a length adjustment apparatus for moving the sampling pipe in the longitudinal direction in the dust removal pipe, and a rotating apparatus for rotating the sampling pipe in the dust removal pipe.

A tool insert is removable from a fluid passage in a drill tool body by pressurizing fluid in a removal volume defined between the tool insert and the drill tool body, to by exerting a net fluid pressure bias on the tool insert in a removal direction along the fluid passage. The tool insert can be an annulus sealing assembly mounted in a rotating control device (RCD), with the removal volume being defined radially between a body of the RCD and a bearing assembly of the annulus sealing assembly. A common hydraulic liquid may be used for lubricating the bearing assembly and for hydraulically actuated removal of the annulus sealing assembly.

A drilling machine including a main body, an operating mechanism; a harmonic speed changer, a centralizer; a drainage tube controlling assembly; a dust collection device, a caterpillar track unit, a drill rod storage frame, and an electric motor-oil pump conversion box. The caterpillar track unit is fixed on both sides of the main body, to move the main body; the operating mechanism and the electric motor-oil pump conversion box are disposed on the main body; the main body includes a main frame provided with a mounting plate; the mounting plate is connected to the operating mechanism through a rotary speed changer; the electric motor-oil pump conversion box is disposed on one side of the operating mechanism. The operating mechanism includes a sliding frame assembly, a sliding guide rod, a propulsion cylinder, a compensating cylinder, and a power head.

Systems and methods for controlling dust. One method includes automatically detecting an operating status of a mining machine. The method also includes automatically, with an electronic processor, adjusting operation of a dust suppression system based on the operating status of the mining machine.

A dust suppression assembly is to be fixed on a handheld device. The dust suppression assembly comprises a device interface member having a top end and a bottom end and an intermediate member having a first intermediate end and a second intermediate end, the first intermediate end adapted to be coupled with the bottom end of the device interface member. Further, the device interface member is having a first channel and the intermediate member is having a second channel, the first channel and second channel joins to form a passage for supplying water to the working end of the tool for suppression of dust, while the handheld device is in use.

A collector circuit and associated circulation process, for intercepting and selectively diverting, at least partially, a fluid flow continuously flowing in a fluid circulation system, for drilling rigs. The collector includes a first sub-circuit with a first duct, with a first valve, and a second duct with a second valve; and; a second sub-circuit; The first sub-circuit, depending on the operating configurations of the first valve and the second valve, is adapted to allow the transit of the fluid flow in the first duct, and selectively divert fluid flow towards the second duct. The second sub-circuit is fluid-dynamically connected to the second duct of the first sub-circuit for receiving fluid flow, diverted by the first sub-circuit, and directing it towards a first outlet of the second sub-circuit. The second sub-circuit and the first sub-circuit are independent, and the second sub-circuit is removable from the collector circuit.

A method for dust suppression for an autonomous drilling machine operating at a work site. The method comprises of generating by a perception module perception data of the work site, receiving at least one machine parameter from a machine sensor of the autonomous drilling machine, predicting by a controller a dust level for the autonomous drilling machine at the work site based on one of the perception data or the machine parameter, determining a fluid discharge rate for a fluid discharge unit based on the predicted dust level, and adjusting the fluid discharge rate based on dust level detected during the drilling operation.
