Deep-hole Drilling

Deep hole drilling investment is larger, higher geological expectations. 

In order to ensure that each borehole achieves the design purpose, a complete set of construction technical scheme must be developed, that is, according to the borehole construction Organization Design. 

The design includes the formation conditions of the mining area and the physical and mechanical properties of the rock, the selection of equipment and power, the selection of drilling tools and drilling methods, drilling structure and technology casing design, flushing fluid and drilling parameters, quality and safety measures, efficiency and construction schedule design, construction organization and management, etc.
