Oxiana is exploring for copper and gold deposits in other parts of Laos. Currently, Sepon hosts eight separate gold deposits and the Khanong copper deposit. Each of five gold deposits comprises pits that are mined to extract the ore. Ore and waste are mined from the Khanong pit, which endures 24 h per day, 365 days a year grinding.

All bolts were installed with the friction bolt slot down to allow water to drain from the hole and to keep the gauges as high as possible on the back side of the drill hole. A fourth bolt was installed near an ore pass about 100 ft back from the face. The ore pass was chosen

Friction hoists require motor power only for the weight of the ore payload The use of balance or tail ropes means that in skip/skip configurations, it's only the weight of the ore payload itself that requires motor power as the rest of the system is in balance. As the friction hoist pulley does not have to store

The two main frictions used are static friction and kinetic friction. The coefficient of static friction for steel is around 0.6–0.15 and the coefficient of kinetic friction is around 0.09–0.6. The making of steel involves many processes and stages. The basic raw materials are coal, iron ore, limestone and various chemicals.

Placer gold ore with high gold content mostly exists in the form of particles. Therefore, the ideal method to process placer gold ore is gravity separation. Rock gold ores have a more complex composition than placer gold ores', thus whether to choose gravity separation and flotation separation depends on the specific composition.

The friction resistance is almost independent of the specific pressure between the surfaces. At low pressures the friction varies directly as the relative surface speed ; At high pressures the friction is high at low velocities falling as the velocity increases to a minimum at about 0,6m/s. The friction then rises in proportion the velocity 2.
