The 14CM15 continuous miner, with a solid-head cutting head system, features a 965 mm (38 in.) conveyor width for standard width entry applications. The 14CM15 comes in multiple models, with various minimum and maximum cutting heights available.

Traction system

The 14CM15 includes our patented OptiDrive AC electronic system, which is coupled to a compact, all-gear transmission to provide smooth, reliable service. The cutter motor feedback and the traction differential features optimize sump performance even in the most demanding applications.  Finally, the brushless AC traction motors are highly reliable and require minimal maintenance.

Cutting system

Joy is known worldwide for the highest performing, most reliable cutter head gear cases in the industry. The 14CM15 includes a solid-head cutting head system, with a variety of cutter bit lacing configurations available.

Hydraulic system

Our hydraulic manifolds, standard on all continuous miner models, reduce hose assemblies and fitting counts to significantly reduce hydraulic fluid leak points.  All serviceable parts for a circuit are in one common location and all pressure check points allow gauge connection/disconnection. Screw-adjusted relief valves are standard, while bolt-on caps permit easy access for troubleshooting/replacement on hydraulic or water segments.

Faceboss control system

Competitive and market pressures mean that you have to produce product at an ever-increasing rate, while always striving to decrease your cost per ton. These goals are only made more difficult by the worsening attributes of available reserves and deteriorating operating conditions.

The Faceboss control system enables your operators to operate equipment at an optimal balance of production rate and cost per ton using a powerful tool set that includes operator assistance tools, automated sequences, advanced diagnostics, machine performance monitoring, and analysis tools. Faceboss is the standard control system platform on all Joy underground mining equipment, which ensures that you receive the same level of optimization for all your Joy equipment.

Learn how Faceboss can help reduce your operating costs.

OptiDrive AC

Joy OptiDrive, an AC variable-frequency drive system, integrates software with the electronic and mechanical systems to provide the following features:

  • Increased tram speed: significantly increases the tractive effort available, improving the equipment’s ability to climb gradients and negotiate difficult roadway conditions
  • Regenerative braking: supplements the mechanical brakes, allowing them to run cooler with extended wear life; regenerative braking is highly effective at automatically maintaining constant speeds when descending gradients
  • Less maintenance: no commutator brushes to inspect and replace mean AC traction motors are typically more reliable, more durable, and require less maintenance than DC traction motors

Learn how OptiDrive can help improve your productivity.

Scrubber systems

The Joy scrubber system - an auxiliary dust control system integrated into the continuous miner - works with the mine ventilation system to help reduce overall local dust exposure. The major system components include:

  • Ductwork
  • Impingement screen
  • De-mister
  • Fan
  • Attenuator

Our scrubber systems can be configured to support localized face ventilation plans by selecting the air volume along with the inlet and discharge locations.

WetheadTM cutter cases

An optional Joy Wethead cooling and wetting system can be integrated in the cutter head to produce a fine spray behind each cutting bit on the cutter drums, thereby:

  • Cooling sparks at point of creation to reduce the potential for frictional ignitions
  • Reducing respirable dust levels to improve operator safety
  • Reducing suspended dust to increase visibility
  • Lubricating the cutter bits to improve cutter bit lifespan

The Wethead system consumes less water (114 lpm (30 gpm) water flow required) than standard miner dust sprays and features a dedicated in-line filtration.

Learn how Wethead keeps your mine environment safer.

SmartZoneTM proximity detection system

The SmartZone proximity detection system is an integrated training device that helps teach your personnel to operate a continuous miner from safe working zones, as well as stay clear of related danger zones. The SmartZone system tracks, recognizes, and logs personnel movements around the machine to provide in-depth analysis for your training initiatives. This option is only available in US and Canada.

Learn how SmartZone keeps train your mine personnel.

SmartConveyorTM

The SmartConveyor uses the latest sound abatement technologies to reduce sound output while improving maintainability. Research results have shown up to a 45% noise exposure reduction for the operator when compared to a standard machine (Mining Engineering, 2011, Vol. 63, No. 7, pp. 83). SmartConveyor combines our patented dual-sprocket conveyor chain, auto-tensioning features, and poly-coated conveyor flights to improve the operating environment.

The patented Joy dual-sprocket continuous miner conveyor chain:

  • Provides 50% improvement in tension strength (over conventional chains)
  • Is driven by two parallel eight-tooth sprockets to provide better torsional rigidity

The increased contact area between the chain and sprocket, coupled with the use of abrasion-resistant materials, significantly decreases the amount of wear, increasing the working life of the components and reducing the probability of abrupt chain breakage. In addition, the cam-style adjusting mechanism automatically compensates for chain slack as the conveyor swings.

Two-way radio remote

The continuous miner two-way radio remote is designed with the operator in mind, featuring large controls for common functions (easily differentiated by feel), common functions loaded to be close to the operators' natural hand positions, and uniquely shaped levers to differentiate functions.
