Production Drilling That Delivers Results
For most metals, extracting the ore requires production drilling and blasting operations. This includes the longhole stoping method commonly used in steeply dipping narrow vein gold operations. Foraco specializes in longhole drilling and blasting, as it demands a high degree of drilling accuracy and controls to minimize dilution. Both pneumatic and electric top hammer drills are used for this mining method that also requires inverse and drop raising operations which provide the opening for blasted ore to break into.
Other production methods include grade control reverse circulation drilling commonly used in open pit gold mining operations. Grade control drilling not only provides confirmation of the ore grades but can also double as a production blast hole.
Some resources like salts of Lithium, Magnesium, Sodium or Potash can be extracted using in situ dilution using underground injection of water which is a natural solvent of many salts. Foraco specializes into “In Situ Leaching” or “Solution Mining” production techniques and deploy part of its water drilling rig fleet to help our customers to inject water or extract brines from deep within the ore bodies.
