Underground Limestone Mine Tunneling with Hybrid TBM

The Blue Ridge Limestone Project, located in southwestern Virginia, USA, involved the excavation of a 4.2 km-long, 6.8 m diameter access and ventilation tunnel through variably weathered, fractured Ordovician limestone. The tunnel serves a new underground limestone mine producing high-purity aggregate for cement manufacturing. Total excavation volume exceeded 150,000 mΒ³.

Challenge: Highly variable ground conditionsβ€”including intact limestone (UCS 80–120 MPa), f...

Coal Mine Longwall Development Drilling Automation

Automated longwall development drilling system deployed at the Blackstone Coal Mine in Queensland, Australia β€” a high-productivity underground metallurgical coal operation. The project covered two 5.2 km development roadways (gate roads) with 6.5 m width Γ— 4.2 m height cross-sections, requiring >12,000 m of precision roof-bolt hole drilling over 18 months.

Challenge: Manual bolting and development drilling posed unacceptable safety risks (roof fa...

Iron Ore Mine High-Angle Bench Drilling

A Tier-1 iron ore mine in the Pilbara region of Western Australia implemented high-angle bench drilling to improve fragmentation and reduce secondary breaking in a hard hematite deposit. The operation involved 15-m-high benches with dip angles up to 75Β°, processing 85 Mtpa of ore. Drilling covered over 200,000 m/month across 12 rotary blasthole rigs.

Challenge: Conventional near-horizontal drilling (≀15Β° from horizontal) failed to achieve c...

Urban Tunnel Project Under Existing Infrastructure

The Urban Tunnel Project Under Existing Infrastructure involved constructing a 1.2-km, 4.5-m-diameter utility tunnel beneath the historic city center of Lyon, France, directly beneath active metro Line B (operational since 1978), a 19th-century stone arch bridge, and a live gas distribution network. The tunnel serves as a new fiber-optic and low-voltage power corridor to support smart-city infrastructure upgrades.

Challenge: Maintaining millimeter-level ground settlement control (<3 mm) beneath existing...
