Ground monitoring devices for underground mines play an integral role in preventing ground movement, which can result in rock falls and tunnel collapses. By providing important data regarding the behaviour of surrounding rock, geophysical instruments for mining operations allow mines to react to rock deformation and assess the performance of the ground support systems.
The National Institute for Occupational Safety and Health (NIOSH) Mining Program applied ground monitoring methods in a variety of mines to provide operators with a history of the stability of the mine opening. This allows for the installation of additional support where needed or the removal of personnel and equipment from potentially hazardous situations.
Ground monitoring devices for mines
Simplified Mining Instruments (SMI) provides a range of ground monitoring devices for underground mines, from extensometers to borehole cameras.
For continuous rock monitoring, SMI offers the Miner’s Helper Extensometer. This two-point extensometer utilizes a reflectorized rod which activates when a user-defined amount of movement occurs. The Miner’s Helper Remote Readable Roof Monitor enables users to gather this data remotely, collecting data in the rib box and indicating when user-defined movement occurs using a flashing LED light.
SMI also offers the Miner’s Eye borehole camera, which provides a straight ahead and 90-degree visualisation with an on-screen distance measurement reading for visual inspections of boreholes as small as 1-5/8 inches in diameter.
For roof monitoring, SMI supplies the Sag Flag, which provides a continuous visual indication of roof sag movement via a reflectorized flag and a scale on the plunger.
