6 FAQs about [Huangshi Pneumatic Down-the-Hole Drill]

What is a down-the-hole drill?

A down-the-hole drill, usually called DTH is mainly a pneumatic powered rock or ground drill, in which the percussive hammer is located directly behind the drill bit, so the percussion mechanism follows the bit down into the drill hole.

Are pneumatic down-the-hole hammers suitable for directional drilling?

Pneumatic down-the-hole hammer, serving as rock-breaking tool, possesses appeal for directional drilling due to its high rate of penetration. However, corresponding experimental studies on existing hammers for directional drilling have rarely been reported, and a model for evaluating their output performance is absent.

What is down-the-hole hammer drilling?

Down-the-hole hammer drilling technology has demonstrated great application potential as a quick and easy drilling technique. LEANOMS is dedicated to enhance the performance and efficiency of down-the-hole hammer drilling technology and will actively investigate and invent in the process of constant development.

What is a down the hole hammer?

One of the most commonly used tools in the drilling industry to meet such challenging scenarios is the Down the Hole Hammer (DTH hammer). DTH hammers are most used in hard rock formations and are designed to tackle complex tasks like drilling in populated areas without putting existing structures at risk.

How does a down-the-hole hammer work?

Along with helping to cool the hammer head, the exhaust gas empties the chiselled rock chips from the hole. The down-the-hole hammer may be lowered as the drill hole deepens as its outside diameter is less than that of the drill hole. In deep hole drilling, this design clearly shows a benefit in down-the-hole hammer drilling.

What technical concerns affect down-the-hole hammer drilling?

Important technical concerns influencing down-the-hole hammer drilling have been investigated in-depth and discussed: drilling limitations, reasonable matching of drill bits, and acceptable hole depth of gas-liquid mixed drilling.
