Filed:

Jul 6, 2001

Appl. No.:

09/900570

Inventors:

Henry E. Wilson - Ironton OH
Gregory E. Hinshaw - Proctorville OH
William S. McIntyre - Proctorville OH

Assignee:

J. H. Fletcher Co., Inc. - Huntington WV

International Classification:

E21B 2108

US Classification:

175 25, 175 27, 175 48, 175 71, 175212

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.

International Classification:

E21D 20/00

US Classification:

4052591, 175 40, 175 52, 175 85

Abstract:

A module and related methods of use in drilling a borehole in a face of a mine passage using a drilling element and installing a bolt in the borehole once formed. The module may include a bolt holder for holding a plurality of bolts and a drilling element holder for holding a plurality of different drilling elements. A manipulator moves along an arcuate path between the bolt and drilling element holders to deliver the respective components to a drill head positioned along the arcuate path. The drill head may also slide relative to the mast in two different directions, and includes a drill guide for determining the location of the face to be worked.

International Classification:

E21B 47/00

US Classification:

175 40, 175 24, 175 27, 175122, 175162

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.
