Difficulties of Drilling Construction in Sawayaerdun Gold Deposit of Xinjiang and the Countermeasures

Abstract:

Sawayaerdun gold deposit is located in the Midwest of Tarim plate across two secondary tectonic units in Dongelai gold-antimony polymetallic metallogenic belt, where the structure is developed with strong rock alteration. Because of high altitude, bad climate conditions and the steep mountain roads, water supply is very difficult for the construction. According to the difficulties of broken rocks, difficult coring, borehole deviation, poor water supply and bad climate conditions encountered in the construction, the specific technical measures are introduced.

Key words:gold deposit; leakage; safety; water supply; core drilling
