Continuous miner with roof bolter 14ED25

Overview
Designed for enhanced productivity in low- to mid-seam entry development, the 14ED25 entry driver integrates a bolting system to enable simultaneous cutting and bolting in a single pass. This single-pass capability addresses the entry gate bottleneck encountered during early roof support installation when roof conditions are weak.

Key benefits

• Exceptional reliability and high uptime
• Extended time between major rebuilds (typically 3–6 years)
• Eliminates the entry gate bottleneck by enabling simultaneous cutting and bolting

Features and benefits (highlights)

• Dual extendable cutterheads: Hydraulic cutterhead extensions retract for easier withdrawals and flexible corner cutting. Wide head cuts up to 16 ft in a single pass. Cutterhead power: 656 HP / 490 kW.
• Faceboss Control System: Operator assistance tools, automated sequences, advanced diagnostics and machine performance monitoring provide actionable insights to optimize operation.
• Dual roof drills: One semi-automatic Joy AFX210 roof bolter with tilt capability is fixed on each side of the miner for rapid roof control installation.
• Front and rear ATRS cylinders: Four hydraulic cylinders stabilize the roof during mining and bolting; engaged by push-button, cylinders pulse to maintain contact with the roof and help protect the operator.
• Hydraulic optimization package: Minimizes hosing and component count, simplifies hose routing to improve maintenance accessibility and streamline rebuilds.
