From August 2013 to October 2014, the drilling team went to Dahutang Tungsten Mining area, Jiujiang, Jiangxi for underground drilling. This mining area is a typical karst stratum, with abundant groundwater and a large amount of water gushing in the borehole, which brings great challenges to the drilling construction.
Our construction team can effectively and quickly deal with complex geological conditions such as karst caves and water gusher to ensure smooth construction and timely completion. In the roadway at 300 meters below, the rich experience and the stable operation of the construction personnel has achieved efficient drilling speed, which fully achieved or exceeded the expectations of clients.
