2.1.1 Geological exploration<br />
Drilling rigs of FDR (Floating Drilling Rig) series are<br />
the basic and the most popular installations applied<br />
for prospecting on building materials and gold.<br />
Mechanical transmission, telescopic mast,<br />
elementary hydraulic circuit makes FDR is the ideal<br />
machine for performing the designated mission.<br />
Drilling rigs of FDR series feature the wide options for<br />
the realization all basic drilling technologies.<br />
Drilling rigs of FDR series are produced from 1991<br />
and proved themselves as reliable, low-maintenance,<br />
effective and easy to operate machine.<br />
Applied drilling technologies:<br />
• standard drilling with the diameter up to 168 mm.<br />
• dry core drilling with the diameters 108…146 mm.<br />
• full-hole auger drilling with the diameter up to<br />
230 mm.<br />
• regular auger drilling with the diameter up to<br />
850 mm.<br />
Positive capabilities of FDR-2:<br />
• As the gear a wide range of wheeled and track<br />
machines can be used: ZIL-131, URAL, KAMAZ<br />
(as well as double cabin), MAZ, transport track<br />
machine ТGM-126, MTLBu, tractors ТТ-4.<br />
• High torque allows building up wells with the<br />
diameter up to 850 mm and the depth up to 20 m.<br />
• The availability of the deck diesel decreases the<br />
load and increases the gear engine life.<br />
• The most simple mechanical and hydraulic circuits<br />
allows the diagnosis and troubleshooting in the<br />
minimum terms.<br />
• The installations of such type are applied in the<br />
prospecting on the building materials more than 20<br />
years.<br />
• High mass of the drilling rig imparts stability in<br />
drilling and moving.<br />
