Open hole drill works because the increase in large-scale projects, the construction unit also increasingly need to use submersible drilling rig, and the type of submersible drilling rig very much, so what are these types of submersible drilling rig works ? Now to introduce the main open-air DTH drilling rig works. Open hole drill racks located mainly through beams on crawler rigs are connected and about the hinge axis articulated way through the rack, in order to adapt to a variety of holes. Rack mounted rotary drill for wind mechanism, promote the lifting mechanism, drill, impact break shuttle lever mechanism. Operation is disposed on the frame machine shed, dust removal system, drivers room. Open-air multi-submersible drilling rig main and auxiliary two drill mobile crusher. Unloading and storage of drill performed by shuttle drill body. Usually by crawler, walking long distances and displacement. Open hole drill rig can be divided into two kinds of dry and wet submersible drilling rig drilling rig DTH professional, dry dust is a mixture of dust and gas directly to the separation and capture of mineral processing equipment. Without professional solar water rigs, but poor dust effects, huge and complicated equipment. Wet dust is the use of wind, water, mixing rock, water, wet dust in the bottom of the hole to make it a wet rock powder pellets or magma breaking out of the hole complex. Dust effect, a simple device, eliminating the second dust source, but drilling efficiency is relatively low. How to choose the DTH drill rig quicken rig workers, to do all the preparation work before, even the best have to choose a good mix of mechanical, or can not achieve the desired effect. DTH drill rig in the choice when you need to note the following: First: hard rock drilling larger than reactive. Each pillar drill teeth and are under greater amount of load. Request bit body and columns teeth having high strength. Second: When drilling in Drillability good soft rock drilling faster   relatively large slag best selection of three or four vane airfoil III: Comparative development drilling in the joints broken in When  to reduce skew. The best choice for a good middle-oriented depressed or protruding type drill. Fourth: When rocks containing clay middle slag hole drilling   best choice is often blocked by the side slagging drill. Fifth: When drilling in relatively good toughness  best selection of wedge-shaped rock drill teeth.
