6 FAQs about [Can the down-the-hole drilling rig be threaded with cables]

How does a cable drilling rig work?

It is a very old technique, slow but steady and only requires one person to operate the rig. A derrick is raised to support the cable tool. The cable tool is a drilling “bit” that is repeatedly raised and dropped in the hole to break up any formation encountered. Then the cable tool is swapped out and a bailer is lowered into the hole.

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 a DTH drill rig?

A down-the-hole drill, usually called DTH Drilling Rig, is basically a mini jackhammer screwed on the bottom of a drill string. The speedy hammer activity breaks hard stone into little flakes and dust and can be dismissed evident by the air exhaust in the DTH hammer.

How to drill a hole with a drill bit?

Specific operation method: whenever drilling begins, the operator must swing the drilling tools gradually to the bottom of the hole. When the frequency down the hole reaches 700~900 times/min and the pressure of the drilling tool on the drill bit reaches about 3kN, it can be the best impact speed.
