  • Publication number: 20070144781
    Abstract: In one aspect, the invention comprises an instrumented drill head for intended use with a drilling machine including a drilling element, such as a drill bit. The drill head includes a case with a rotatable chuck for the drilling element. A first sensor associated with the drill head senses and generates an output signal representative of a first parameter of the drilling operation. A transmitter wirelessly transmits the signal to a receiver associated with a controller. A roof bolting machine including the drill head and a resin inserter is also disclosed, as are related methods of instrumenting a drill head and drilling using an instrumented drill head.

  • Patent number: 6637522
    Abstract: 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 using enhanced computer control. A drill stem with a bit is used to form the drill hole. A flushing mechanism utilizes vacuum or pressurized water to create a bailing fluid flow for flushing the cuttings and dust from the drill hole for disposal. A transducer monitors at least one first parameter of the bailing fluid flow, and a sensor may also monitor at least one second parameter of a flow of a driving fluid under pressure for feeding the drill stem and bit into the earth. A controller is utilized to regulate the rate of feed and/or driving of the stem and bit dependent on the levels of the parameters being monitored.

  • Patent number: 6216800
    Abstract: 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.

  • Patent number: 5951208
    Abstract: A method of roof/side wall roof bolting in-situ includes the steps of drilling a bore hole, loading a rupturable resin cartridge into a lightweight, tubular wand through the delivery end, manually placing the wand with the delivery end adjacent the mouth of the bore hole, pushing the cartridge through the wand for transfer into the bore hole, and inserting the roof bolt to rupture the cartridge and for setting into place in the rock. The related apparatus includes a tubular wand, a flexible pusher that is extensible through the wand and into the bore hole for transfer of the cartridge and a driver in the form of a flexible snake assembly from a reel to push the cartridge. The snake assembly includes a cylindrical head on the end and a plastic retainer fits over the trailing end of the cartridge to prevent retro movement and to provide protection from premature rupture. A handle at the proximate end of the wand provides for easy manipulation of the wand.
