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.
