Enlow Fork Mine, part of the Pennsylvania Mining Complex in Washington County, Pennsylvania, is a high-production underground coal operation extracting high-volatility bituminous coal hundreds of feet below the surface. To keep development and long wall operations supplied, the mine relies on a slope car hoist traveling more than 800 feet between surface and underground. Historically, the hoist operator could only judge the car’s position by reading the footage on the hoist cable, with no direct visibility into what was happening in the slope. Working with Rajant and integration partner Comtrol International, the mine implemented a real-time wireless video solution powered by Rajant Kinetic Mesh® to give operators and management continuous visibility of the slope car’s movement, improving safety, situational awareness, and operational confidence.
The Challenge:
Enlow Fork Mine depends on a slope car hoist system to move supplies, materials, and equipment between the surface and underground workings more than 800 feet below. Previously, the hoist operator could only estimate the car’s position using a footage counter on the hoist cable. There was no direct visibility into the slope, no way to confirm whether the track was clear, and no visual indication of potential obstructions or unsafe conditions.

Identifying early the need for private network infrastructure that could effectively support fully mobile wireless communications in industrial settings, Rajant Corporation developed its patented Kinetic Mesh® technology—and in turn became the pioneer provider of the most adaptable, scalable, and readily deployed fully mobile network on the market today.
Rajant was established in October 2001, after founders Robert Schena and Paul Hellhake recognized the significant shortcomings in traditional wireless mesh technology, particularly when it came to mobile voice and data networks used by first responders. The Rajant team envisioned a new, more robust mesh technology that would allow these networks to be fully mobile and mobility-enabled, and operate reliably in even the most demanding environments. Enter the Rajant Kinetic Mesh® network.
