"LEAVE THE ROCK IN THE MINE"

Longwall

Problem:
When controlling to the floor, all the coals needs to be removed with minimal out-of-seam dilution. Controlling to a thin-layer or set amount of coal at the roof is often desirable.

Solution:
A Longwall Gamma Detector has been developed and patented by GMS. These armored detectors are mounted on the cowl of the longwall machine and are designed to not only give accurate and reliable readings, but also able to withstand this very harsh environment.
