Comtrol International is recognized as a major designer and manufacturer of industrial communications and control systems for more than 25 years. They have equipment for your mine paging and telephone needs (MSHA approved).

MineTracer is an integrated wireless communication and tracking system designed specifically for use in underground mines. MineTracer was developed to address the MINER Act and West Virginia Rules for communication-tracking equipment. The installed coverage area is completely flexible - ranging from 100% travel-entry and work area coverage to zonal coverage.

In the event of an accident, the system operates on battery power continuously for at least 48 hours after the loss of AC power in the mine. Every component of the MineTracer system has been approved by MSHA for intrinsic safety.

With the development of the HazardAvert® System, Frederick Mining Controls, LLC has positioned itself as an industry leader in Proximity Detection and Avoidance. Working in partnership with the Mine Safety and Health Administration (MSHA) to reduce crushing and pinning type fatal accidents, the HazardAvert© was the first Proximity Detection system approved by MSHA.
