Productive longwall working environments require a powerful combination of mining operations and specialised expertise. When you choose a Joy-engineered PRS solution, our team works closely with you to tailor the design to meet your specific needs and applications. We’ll then work with your preferred manufacturing partner and collaborate with your selected vendors through installation, integration and operation.
Joy-engineered structures are recognised throughout the mining industry for proven, reliable, long service life with a low cost of ownership.
Higher life-cycle results in lower ownership costs. An intelligent design features an innovative leg feed locking system with no transverse welds and bespoke leg seals. Single, and double telescopic designs and various leg bore sizes are available.
Roof supports keep pace with shearer cutting for excellent productivity and fast cycle times. The modular and expandable Joy Compak Next Gen has a faster cycle time than its predecessor and is 5-38% quicker than other similar market control valves.
Advanced automation for productivity and protection
Add next-level automation with a Joy electro-hydraulic control system integrated with your longwall and mine-wide system. Automatic shearer and roof support gate turn arounds combined with remote management, driving an autonomous face with our next generation RS20n control system and it’s 1 GB/s ethernet high-speed communications backbone. Can be fully integrated with the coal clearance system reducing the total cost of ownership.
The Joy Personal Proximity Detection system (PPD) can prevent the movement of an advancing shield if an operators PPD tag is detected. Full integration into the Joy electro-hydraulic control system eliminating the need for additional fixed components – no plug ins required.
Observe operations with underground or surface video monitoring of your entire longwall operation. Rugged cameras provide real-time video and complements Joy’s high-fidelity 3D visualization system. Integral to remote operations.
Comprehensive OE and extended life tests on all structural, hydraulic and control components can be customised or specified to international standards. All new structural fabrications undergo detailed finite element analysis (FEA) with full engineering support throughout the process.
Smart Solutions
We help solve our customers’ toughest challenges using data-driven intelligence, collaboration and service execution. Our goal is to help reduce costs and increase productivity to help our customers achieve their operating and financial goals.
Faster, more informed decisions about your mining operations can drive productivity. The Joy Faceboss RS20n longwall control monitoring system makes that possible by helping you unlock the benefits of automation and intelligent controls. It enables the connection of intelligent devices, sensors and technologies to the mine’s network to support high levels of longwall automation.
Unlock the power of automation for the journey to zero harm and increased productivity with the global dual solenoid valve for powered roof supports. Its serial connectivity enables a distributed system for fast response. Can be used with any PRS system; common control with shearer and AFC advances Komatsu remote operation capabilities.
To help realize the potential of your longwall mining operations, the Joy Compak Next Gen helps facilitate your shearer cutting rate and delivers exceptional cycle time performance.
Quick Benefits:
*Comparison based on previous model
**Comparison based on previous model (like-for-like designs) without extra add-ons
The improved consistency and elimination of virtually all alignment shears can increase production up to 10%.* Inertia navigation system in shearer measures the straightness of the longwall and the Faceboss system uses that data to make path corrections.
*Based on internal testing vs. longwall without feature
This system advances the journey to zero harm by preventing movement of an advancing shield if the system detects a worker in harm’s way. Full integration into the Faceboss Control System eliminates the need for additional components.
