As far as productivity, the continuous miner sections would see shorter conveyor belt move times, which mean more time dedicated to production. Joy believes conveyor belt moves could be completed with one worker instead of the two or more workers needed to move feeder-breakers and separate tailpieces. The two or three additional pieces of equipment that would normally be required to move a separate belt tailpiece are freed for use on other projects. The system would also aid in the installation of conveyor structure reducing or possibly eliminating manual belt handling with belt handling devices.
The system would also improve the alignment between the conveyor and the feeder-breaker, reducing issues with coal loading (spillage) and conveyor wear. The stability jacks (roof beam supports) have sufficient traction to pull the conveyor belt. The miners would not need to anchor the feeder-breaker tailpiece to mine roof, floor and ribs.
Seeking to improve its longwall panel advancement rate, a mine in the United States recently purchased two JOY BF-14A-59-64C Feeder-Breakers with mounted tailpieces and has enjoyed increased productivity due to quicker conveyor belt moves. Joy engineers in Millersburg, Ky., designed the feeder-breakers with mounted tailpieces. The roof beam supports (stability jacks) stabilize the feeder-breakers and belt tailpieces and protect them from the high tension associated with moving several thousand feet of belt. When a conveyor belt needs to be moved, the roof beam supports are lowered and the feeder-breaker trams toward the mine face, pulling the panel conveyor belt with it. When the tailpiece reaches its new location, the roof supports are anchored back into the roof. The Feeder-Breakers are processing up to 1,200 tons per hour.
The feeder-breakers are also equipped with many other upgrades and features, including belt spreaders and crawlers with maximum draw bar pull; direct-drive breakers that reduce wear on components such as chains and sprockets; 18-inch reverse crawlers that provide maximum torque operation at low speed and are very well suited for pulling belt structure; three-way dumps for shuttle car unloading; 3.5-inch pitch conveyor chains; and umbilical remote trams.
The Hawk and Eagle Metalarm Metal Detectors use pulse induction technology that offers balance coil detection sensitivity and performance. The Hawk coil is typically used for standard applications with a sensitivity equal to approximately 5% of aperture height; less sensitive settings are available. The Hawk is designed for use on steel cord belts. The Eagle is used where higher sensitivities are required, and is capable of detecting a ferrous sphere equal to 2% of the aperture height.

Gates EFG6K MegaSys hydraulic hose flexes up to one-half the SAE specification, making it easier to install assemblies in tight applications. The six-spiral wire hose is recommended for extreme high-pressure, high-impulse applications on underground mining equipment. Its flexibility saves overall hose assembly length and costs, and reduces the need for bent tube fittings. To lower inventory requirements, the Gates hose is engineered with a constant 6,000-psi pressure rating in all sizes. An optional MegaTuff super-tough hose cover, offering 300 times the abrasion resistance of standard hose covers, solves abrasion and wear problems. The EFG6K MegaSys hose is designed to meet the requirements of SAE 100R15, the performance requirements of EN 856 4SP and EN 856 4SH, and has a MSHA 2G flame resistance acceptance designation. The Nitrile tube is compatible with biodegradable hydraulic fluids, including polyolester, polyglycol and vegetable oil, as well as standard petroleum-based fluids. A new, color-coded layline treatment, used exclusively for MegaSys hoses, makes Gates hoses easy to identify in stock and in service.

Key Improvements to Dowex Marathon C10
Dow Water & Process Solutions announces key improvements to Dowex Marathon C10, an ion exchange resin that can be used for effective removal of contaminants from water in industrial water demineralization, condensate polishing and softening. C10 is a strong acid cation exchange resin with a uniform particle size. The uniform particle size beads exhibit more uniform exhaustion, regeneration and backwash compared to conventionally sized resins. The higher level of cross-linking also shows exceptional stability to compressive, osmotic and oxidative stresses. Improvements to the resin include reduction in mean particle size increasing resin kinetic performance by 15%.

Belt Scale Integrator
The Siemens Milltronics BW500/L was developed specifically for simple applications with belt scales. It features two relays capable of calculating rate, totalized weight, belt loading and belt speed. Based on a patented electronic load cell-balancing feature, the upgraded BW500 and new BW500/L provide unequaled accuracy and improved efficiency in simple and complex applications.
When used in conjunction with a speed sensor and weigh bridge, the BW500/L is well suited for bulk weighing of product in processes as the material is moved on a conveyor belt. This measurement can be used to provide a signal to a control device that can be used for batch or feed rate control. This belt scale integrator can also be used to measure bulk inventory as is moved to and from silos, bins or storage piles.
Plant Monitoring Package
The Senscape package allows users to view the status of monitoring equipment from remote locations. By removing the graphic mimic displays and logic functions found in more costly SCADA packages, users view data in a simple tabular format, making the system more cost effective for simple systems. Plant parameters such as set-point and relay states can be changed by the user where applicable. The alarm summary display ‘pops-up’ over other displays when an alarm is activated. For the display of recent data, the user can view on-screen trends, and data and events can be logged to files for offline analysis. The system connects to the plant via the Modbus protocol over an RS485 serial link network or Ethernet TCP/IP network. Multiple networks including mixing RS485 and TCP/IP are supported.
InSeT Tracking and Communication System Receives MSHA Approval
InSeT Systems’ tracking and communications system has been approved for use by the Mine Safety and Health Administration (MSHA). The system combines wireless technology with an innovative handheld unit carried by each miner that is accurate to within 25 ft after 24 hours of operation. It uses InSeT’s patented Inertial Sensor Tracking system with miniature inertial sensors, proprietary software, and a wireless mesh radio network to display and record the real-time location of miners working underground. The result is a robust system with the ability to accurately track miners, enabling rapid, highly targeted rescue efforts should a mining disaster occur. The handheld part of the unit also allows two-way communication with the person carrying it. The approval number for the product on the MSHA Web site is 23A110001-0. This means the system is approved for use in underground environments such as coal mines, whose gaseous atmospheres present explosion hazards.
