Standard Penetration Test (SPT) on Sonic Rig | MC900P | Legion Drilling

SPT Testing in Mine Tailings & Tailings Dams | Sonic Drilling Rig Procedure | Comacchio MC900P | Legion Drilling Australia Watch Legion Drilling Australia demonstrate Standard Penetration Test (SPT) on their Comacchio MC900P Sonic Drilling Rig — specifically suited for mine tailings investigations, tailings dam assessments, and mining geotechnical projects. See the fully automated 63.5 kg SPT hammer in action, driving the split-spoon sampler in precise 150 mm increments to deliver reliable, real-time N-value data for tailings storage facility (TSF) stability and environmental site assessments. *Why Sonic Drilling + SPT is ideal for Mine Tailings & Mining Projects* Sonic rigs excel in mine waste, tailings dams, and variable ground conditions common across Australian mining operations. They deliver near-100% sample recovery with minimal disturbance, while seamlessly supporting SPT testing for accurate geotechnical parameters. This combination provides engineers with high-quality continuous core samples plus reliable in-situ SPT N-values — critical for tailings dam stability analysis, foundation design, bearing capacity assessment, and environmental risk evaluation. 🔍 Standard SPT Hammer Weight & Procedure (ASTM D1586 & AS 1289.6.3.1) According to ASTM D1586 and Australian Standard AS 1289.6.3.1, the SPT hammer weighs *63.5 kg (140 ± 2 lbf)* and drops from **760 mm**. Legion Drilling uses fully automated, safety-guarded SPT hammers for consistent energy delivery and repeatable results — even in challenging mine tailings and waste rock. *Key advantages for mining & environmental engineers:* High sample recovery in tailings and mine waste Minimal cross-contamination risk with temporary casing Excellent access on low ground pressure rigs for remote TSF sites Combined sonic coring + SPT capability on one rig Reliable data for ANCOLD guidelines, tailings management, and geotechnical reporting Legion Drilling is Australia’s premier sonic and geotechnical drilling contractor, trusted by mining companies for tailings dam investigations, mine waste assessments, and contaminated land projects. We operate Comacchio MC900P and other high-capacity sonic rigs from depots in Sydney, Brisbane, Townsville, Albury-Wodonga and Darwin. 👉 Mining companies, geotechnical consultants or environmental engineers — need SPT testing or sonic drilling for tailings or mine waste projects?
