MHL SMI Extensometer

The Miner’s Helper Extensometer is a single-point extensometer used to measure roof sag. It utilizes a reflectorized rod that is activated when a user-defined amount of movement has occurred.

Similarly, the Sag Flag provides a continuous visual indication of movement as part of an early warning system and is a great tool for ground control management.

The Miner’s Helper Remote Readable Roof Monitor is used to reliably measure rock strata separations or roof sag. Building on the functionality of the standard Miner’s Helper, this monitor enables the user to remotely gather data from the readout box connected via an electrical cable.

The Miner’s Eye Borescope camera can be used for visual inspections of boreholes, even those as small as 1-5/8 inches in diameter. It provides straight-ahead and 90-degree visualization, with an on-screen distance measurement reading so users can assess the competency of roof geology and pillars.

These products are important to the health and safety of underground workers and help to prevent disasters such as mine roof collapses. All SMI products are available in standard packages and customized for your project. Please call 606-573-1000 to discuss further.
