The new unit was designed for DRAGIN Drilling and is the only one of its kind in the US. The rig itself is a modified CME-95; a drill rig manufactured by the St. Louis-based Central Mine Equipment Company. This unit was designed to tackle deep and large diameter auger drilling projects. The primary modification made to the CME-95 was to increase the rotary toque by approximately 20%. Applications include deep auger drilling (up to depths of 350 feet using 4.25-inch hollow-stem augers) for the delineation of deep contaminate plumes and investigation of new water supplies. This feature has been of particular importance for the ongoing mediation work at the Massachusetts Military Reservation on Cape Cod.
The second modification of importance was the re-designing of the upright frame. The new design allows for the use of a 24-inch O.D. hollow-stem auger. Applications for this feature and specialty equipment include landfill gas vent well and large diameter recovery well installations. DRAGIN Drilling continues to be the sole provider of this 24-inch auger drilling service.
