Korean Metals Exploration has identified a new surface mining method which could potentially be used on its projects in South Korea.\u00a0Modern, \u2018cutting-edge\u2019 mining and drilling processes are proposed by the Company. Large diameter Pile Top RC drilling technology is well suited to mining the mineralized veins found within the Company\u2019s projects.<\/p>\n

Novamera Inc.<\/em>\u00a0has developed an innovative and new mining method called\u00a0Sustainable Mining by Drilling<\/strong>\u00a0(\u201cSMD<\/strong>\u201d). SMD uses conventional Pile Top RCD drills used successfully by the Construction Industry and the proven Reverse Circulation Drilling (\u201cRCD\u201d) method to extract ore from steeply-dipping narrow vein deposits.<\/p>\n

Pile Top Reverse Circulation Drill Rig\u00a0<\/span><\/h2>\n

 <\/p>\n

Circulation Drilling (\u201cRCD\u201d) with optimized airlift is a proven method for Pile Top RCD drill rigs. There are several manufacturers of Pile Top RCD drills including\u00a0MH Wirth<\/em>\u00a0(Germany),\u00a0LDD<\/em>\u00a0(UK) and\u00a0Buma CE<\/em>\u00a0(South Korea). The drill string components are of modular design and suitable for any depth and hole diameter up to 4.5 metres. Hole diameter should be selected to optimize rate of penetration and vein width. A Pile Top RCD fitted with a 2-metre diameter drill bit is estimated to be capable of \u201cmining\u201d about 7 tonnes of Ore per hour.<\/p>\n

The Pile Top RCD is capable of drilling holes with inclinations from 90o<\/sup>\u00a0(vertical) to 72o<\/sup>. The working deck has variable geometry to keep it level.<\/p>\n

Drilling depth is increased by simply adding another drill pipe, using an on-board derrick crane. Each Drill Pipe run is 3m in length and is attached by 8 bolts to the next pipe using a pneumatic air-impact wrench. A Drill Rod Pipe Stabilizer is usually fitted to every 3 runs. The Stabilizer is a non-revolving Drill Pipe fitted with arms which expand out to fit to the hole wall, helping to add stability to the RCD drilling process.<\/p>\n
