6 FAQs about [Going abroad to operate down-the-hole drilling rigs]
How do drill rigs work?
Conventional drilling rigs use the power of an electric motor or a diesel engine, which is transmitted to the turntable through the operating system to drive the drill bit connected to the drill rod to grind and cut the rock to achieve the purpose of drilling. This kind of drill first solves the ground power.
What is down-the-hole drilling (DTH)?
Down-the-hole drilling (DTH) essentially involves a drilling hammer at the bottom of a drill string. It relies on three elements for drilling holes: bit loading (weight), rotation and air. These active elements combine to be efficient at crushing rock. As the drill string slowly rotates, the drilling hammer is forced into the rock repeatedly.
How long did it take to drill a 12,000 ft hole?
The original estimate for completion of a 12,000-foot hole was 30 days using the conventional rotary technique, which was reduced to 13 days using the DTH method. Before DTH was used, drillers would typically case the vertical portion of the well and convert to rotary drilling to drill at a tangent.
What are the disadvantages of a DTH drilling rig?
Conventional drilling rigs have cumbersome groundwork in bedrock drilling, frequent lifting and lowering of the drill, large labor consumption, slow speed, and comprehensive calculation of capital consumption, and these disadvantages are difficult to change. DTH drilling rigs mainly use compressed air.
How does DTH drilling work?
With DTH drilling, contractors can change the drill that they were using for the current directional bore to a rock drill when they encounter rock by connecting the drill with a compressor and a steerable hammer. Well drilling also needed changes to be made to rotary drilling when the well needed to take a turn.
Which drilling method is best for cities?
The DTH method is the most productive and cost-effective method. It is environmentally friendly, as it produces lesser noise and vibration compared to other drilling methods making it ideal for cities.
