A DTH (down-the-hole) drill is basically a
mini jackhammer attached on the bottom of a drill string. It is one of the
fastest ways to drill hard rock. It is rotary with percussive type drilling.
The direction of drilling is usually upwards instead of downwards. It can drill
up to 500 feet or 150 meters per day. In DTH drilling, the percussion mechanism
generally called the hammer mechanism. Hammer is located directly behind the
drill bit. It is commonly used for drilling long holes, for blasting, water
wells, shallow gas and oil wells. In mining industry, it is used for sampling
using reverse circulation technique.
The key benefits are included allows plowing
narrow bodies, low cost of development, and simple equipment for drilling &
loading. Beside this, few of the disadvantages are included security problems
at the time of working and control of ore grade can be difficult.
According to study, “Global
DTH Drill Market 2019 by Manufacturers, Regions, Type and Application,
Forecast to 2024” the key companies operating in the global DTH drill market
are Bulroc, Sandeep Drilltech, Mincon, Drill King, Rock-Tech International,
EDM, Mindrill Systems & Solutions, Dynadrill and Prodrill Equipment,
Rockmore. The key players are investing heavily in mounting their capacity to
meet the rise in demand for metals and ores, due to the growth of the
automotive sector.
Based on type, DTH drill market is segmented
into electric drive DTH drills and internal combustion DTH drills. Based on
tool type, market is segmented into convex front, flat front, concave front,
speed bit and rocket bit. Based on drill depth, market is segmented into up-to
50 m, 51 to 100 m and above 100 m. Based
on mounting type, market is segmented into truck mounted, track or crawler mounted
and others. Based on drill type, market is segmented into horizontal drilling
and vertical drilling. Based on operation type, market is segmented into deep
hole drilling, well drilling, foundation drilling and blast hole drilling. In
addition, based on end-use industry, market is segmented into construction
industry, mining & quarry industry, oil & gas industry, water-well
drilling and others.
The DTH drill market is driven by rise in
mining activities, followed by increase in blast hole drilling for open pit
mining, rise in demand for the rare earthy metals & natural resources, and
growth in demand for underground drill equipment. However, rise in prices of
raw materials and increase in government regulations related to the drilling
operations may impact the market. Moreover, growth in technological
advancements through artificial intelligence (AI) and Internet-of-Things (IoT)
is a key opportunity for market.
Based on geography, the North-American region
dominates the DTH drill market owing to rise in miming activities and increase
in replacement & up-gradation of underground infrastructure in the region.
The European and North-American regions are estimated to witness higher growth
rate due to increased horizontal drilling & unconventional drilling
activities and growth in economy over the forecast period. In upcoming years,
it is anticipated that future of the market will be bright on account of rapid
urbanization, growth in oil & gas discovery activities and intense
competition among construction companies along with stringent timelines to
accomplish infrastructure projects during the forecast period.
