The mining sub-hole drill is slow and prone to getting stuck? ANNENG's advanced model is stable and fast, and it's hassle-free.
When using ordinary sub-hole drills in mines, the biggest headache is that drilling through hard rocks is slow and it often gets stuck. This requires a lot of time to deal with and can delay the construction schedule by half a day. The machine parts are also not durable, and they need to be replaced frequently, causing costs to rise rapidly. What's more, it doesn't work well with Hydraulic Mining Drilling Rigs or other equipment, and there are frequent interruptions in work. ANNENG's Advanced Down-the-Hole Drilling Equipment for Mining precisely addresses these issues. The drill is sturdy, has automatic anti-stuck function, and can be used smoothly with other equipment. Compared to ordinary drilling rigs, it is better at drilling deep and hard rocks in mines, is fast and stable, and doesn't delay work.
ANNENG's sub-hole drill is specifically designed for hard rock mining in mines. It has sufficient air pressure and strong impact force, and drills through hard rocks at a speed more than half faster than the old model. The drill rods and drill bits are made of alloy reinforcement, which is very wear-resistant. The core parts can withstand 1500 hours of high-intensity operation and are much more durable than ordinary machines. It is different from Hydraulic Well Drilling Rigs, which are used for drilling wells, and unlike Small Remote Control Drilling Rigs, which can only handle light tasks. This drill focuses on drilling in complex mine strata and deep into hard rocks. It can work seamlessly with Hydraulic Mining Drilling Rigs, removing the surface rocks first and then drilling deeper. The entire process is not interrupted. The machine also has intelligent sensing, which can monitor the changes in drilling pressure in real time and automatically adjust the impact frequency when encountering hard rock layers, minimizing the risk of getting stuck. The operation interface is simple and it is easy to use in mining environments.
The impact air pressure of this machine can reach over 24 MPa, with 1800 to 2200 impacts per minute. In hard rock areas, it can drill more than 12 meters per hour. The drill bit diameter ranges from 90 to 165 mm, and the deepest drilling depth can reach 50 meters. It is sufficient for both blasting holes and exploration holes. The anti-stuck system reacts very quickly, taking only 0.3 seconds to adjust, without the need for manual monitoring. The drill rod is made of high-strength alloy steel, which is very durable and can be used for half the time compared to ordinary drill rods. The machine has a moderate weight, is easy to move, and does not require specially leveled ground when working with Hydraulic Mining Drilling Rigs. The dust and water resistance are well designed, and it can work stably even in dusty and humid mining environments.
Product features
1.Fast and durable: Sufficient air pressure, sturdy drill tools, fast drilling through hard rocks, core parts are 50% more durable than ordinary sub-hole drills;
2.Automatic anti-stuck: Can sense pressure in real time, adjust parameters by itself, reduces the probability of getting stuck by 70%, and doesn't require frequent shutdowns for handling;
3.Smooth operation: Works smoothly with Hydraulic Mining Drilling Rigs, making multi-device operations in mines smooth, and it can work seamlessly with Hydraulic Mining Drilling Rigs.
Tips
1.When drilling hard rocks, set the air pressure to 22-24 MPa for higher crushing efficiency;
2.Check the wear of the drill bit every day. Replace it immediately if the alloy teeth wear more than 3 mm, otherwise it will affect the drilling accuracy;
3.When working with Hydraulic Mining Drilling Rigs, plan the drilling location and transportation route in advance to save time.
This machine can be used for both blasting holes in metal mines and exploration in non-metal mines. When stripping rocks in open-pit mines, together with the Hydraulic Mining Drilling Rig, the surface layer is broken first before drilling deep holes, doubling the working efficiency; when reinforcing the mine slopes, precise drilling is carried out to install anchor rods, ensuring safety as well. Compared to ordinary Drilling Rigs, it performs much more reliably in the high-dust and hard-rock environment of mines.
After being used in a copper mine, it was able to drill 120 meters more per day, and the construction period was directly shortened by a quarter. The intelligent anti-stuck system reduced the wear of the drill tools, and the cost of replacing parts alone saved 80,000 yuan in a year. When used in conjunction with the Hydraulic Mining Drilling Rig, the entire mine worked 30% faster, and the machines rarely stopped for maintenance, operating normally every day. Mine engineer Mr. Zhao said, "The sub-bit drill used to drill at most 80 meters per day and often got stuck, requiring handling 5 times a week. After replacing with this ANNENG model, it can drill over 120 meters per day in hard rock areas, and stuck situations now occur not even once a month. It's so convenient!" Manager Wang of the mining project also said, "This machine works very well in conjunction with our Hydraulic Mining Drilling Rig, without any interruption in work. It didn't have any errors in a dusty environment, and is much more reliable than ordinary Drilling Rigs." Mr. Liu, the equipment purchaser, even repurchased it three times: "After comparing four sub-bit drills, this one drills faster, is more durable, and is particularly suitable for hard-rock operations in metal mines. The people in the mining area all think it's very useful."
