Reverse circulation drilling (RCD) is an effective method for ore body sampling. Its main advantages are speed and low cost of works. RC-drilling is carried out with the help of special downhole hammer diameter 121mm – 159mm. Speed of drilling can reach 40 m/hour. Also one more obvious advantage of this type of drilling is water independence during drilling process, that makes possible to use it in a complex geological environment.
“Rosgeoperspektiva” group of companies pays special attention to introduction and development of RC- drilling technologies.
Drilling equipment stock consists of all the necessary equipment for RC-drilling: ROCK DRILL 5000, WDH 500, MAXCAT 12, Schramm T 685 WS. Efficiency and reliability of this equipment were tested during years of works in different territories (the Chelyabinsk, Sverdlovsk, Orenburg regions of the Russian Federation, the Komi Republic, the Chukotka Autonomous District, the Far East, the Republic of Kazakhstan and the Kyrgyz Republic).
