The essence of rock drilling with a DTH drilling rig is to make the DTH hammer dive into the hole during the rock drilling process to reduce the energy loss caused by the impact energy transmitted by the DTH drill rods, thereby reducing the impact of hole depth on rock drilling efficiency.

The combination of dth drill bits and air compressors greatly improves project efficiency, which is usually 15 to 20 times that of hydraulic drilling rigs. If a well is drilled at the same time, if it takes 15 days with an ordinary hydraulic drilling rig, it will only take one day with a down-the-hole drilling rig. Greatly save labor and fuel consumption costs.

However, while meeting the requirements of rapid drilling, it also has to bear corresponding costs. First,dth hammer bit price itself is often much higher than that of the hydraulic one; and the loss of the dth hammer drill bits, the footage is fast, and the wear is also quick.

How to reduce loss costs and save money? Here is a summary of some practical experience, I hope it will be useful to you:

1. Choose the right dth hammerbit

DTH hammer drill bits are selected based on rock conditions (hardness, abrasiveness) and drill type (high wind pressure, low wind pressure). Different forms of alloy teeth and tooth arrangement methods are suitable for drilling different rocks. Choosing the correct dth hammer button bits is the prerequisite for obtaining the best results;

2. Pay attention to installing the down-the-hole drill bit

When installing a down-the-hole bits, place the drill bit gently into the drill sleeve of the down the hole hammer. Do not hit it with force to avoid damaging the drill bit shank or the drill sleeve;

3. Ensure adequate air pressure

During the rock drilling process, it is necessary to ensure that the air pressure of the down-the-hole drilling rig is sufficient. If the dth hammer works intermittently, or the blast hole powder discharge is not smooth, the compressed air system of the down-the-hole drilling rig should be checked to ensure that there is no rock slag in the hole during the drilling process;

4. Check for metal objects in the air

If a metal object is found falling into the hole, it should be sucked out with a magnet or taken out by other methods in time to avoid damaging the drill bit;

5. When replacing thedth hammer drill bits, pay attention to the size of the blast hole.

When replacing the drill bit, pay attention to the size of the drilled blast hole. If the diameter of the drill bit is excessively worn but the blast hole has not yet been drilled, the drill bit cannot be replaced to avoid drill sticking. The job can be done with an old drill bit that has been used and has about the same worn diameter.
