The holes defined in the air intake block may be covered by screens to prevent the entrance of large particles into the air intake block. The air intake block is disposed to provide sufficient suction lateral to the longitudinal axis of the drill steel in order to remove fine particles of quartz and dust from the air adjacent the entrance of the drill hole.
42 In-situ drilling system with dust collection and overload control US09198327 1998-11-24 US06216800B1 2001-04-17 Henry E. Wilson; Gregory E. Hinshaw; William S. McIntyre, Jr.
An apparatus and method is provided for substantially continuously drilling and disposing of drill cuttings and dust to minimize airborne contamination while providing protection against overload. A drill stem with a bit is advanced by a drill head to form the drill hole. A flushing mechanism utilizes vacuum or pressurized water for flushing the cuttings and dust from the drill hole for disposal. A transducer monitors the negative or positive gauge pressure. A controller is utilized to regulate the rate of drilling dependent on the signal level of the pressure being monitored. In the preferred embodiment utilizing air, the passage in the drill stem removes the cuttings/dust and is connected to a transfer duct, which in turn is connected to a filter and the intake side of a blower. The controller is programmable to establish the optimum rate of feed of the drill head. The rotary motion of the drill bit can also be regulated by the controller. Preferably, the threshold level to determine an approaching overload is in the range of 10% to 20% over the normal gauge pressure of 0.5-4 inches Hg. The feed of the drill stem and/or the rotation is slowed or stopped in an approaching overload condition, and automatically reestablished once the condition is past. In the alternative embodiment, the pressurized water flows through the passage in the drill stem and bit forming a slurry with the cuttings/dust. The slurry flows around the drill stem/bit and is deposited outside the drill hole.

45 Dust conveying and collecting system and method US223036 1981-01-07 US4434861A 1984-03-06 D. Franklin Howeth
A conveying and collection system adapted for drilling rigs for conveying drill cuttings entrained with a bailing air flow stream emanating from the drillhole includes a generally tubular head fitted around the drillhole having a flow deflecting surface portion adapted to deflect the flow stream of drill cuttings into a conveying enclosure whereby velocity reduction and change of direction of the flow stream will separate relatively coarse cuttings. A mechanical conveyor may be disposed in the enclosure to convey the cuttings to a point remote from the drillhole. The head may be extended and retracted with respect to the drill rig deck plate by actuators controlled in accordance with the conduction of bailing air to the drill stem. One embodiment of the head comprises an enclosure formed by overlapping helical convolutions of a flat spirally coiled band. The head may be provided with retractable gate members remotely actuated to move clear of an opening in the head which is of sufficient size to permit movement of drill stem coupling members and/or the drill bit through the head during drilling operations. A filter unit has a plurality of separate filter element chambers in which are disposed porous media filter elements arranged side by side along the flow path of a bailing air flow stream entering the filter unit housing so that the lower velocity portions of the flow stream are diverted into the filter element chambers and forced to flow in a vortical manner to provide inertial separation prior to flow through the filter elements. A suction pump on the filter unit is operable to vary its inlet volumetric capacity to provide a partial vacuum condition throughout the collection system to minimize leakage flow of dust laden bailing air out of the system.
46 Method of binding dust US316024 1981-10-28 US4406330A 1983-09-27 Goran H. Jysky
In rock drilling, the dust-laden flushing air from the borehole is drawn through a coarse dust separator and a filter unit. A mixing apparatus is screwed to the bottom of the filter unit and in accordance with this invention the dust that falls from the filter unit is fed in batches to a mixing chamber of the mixing apparatus in which it is mixed with a liquid binder. The dust from the coarse dust separator is directly dumped on the ground and the fine dust from the mixing apparatus is also dumped on the ground.
