Use and maintenance of down-the-hole impactor（DTH hammer）
Down-the-hole impactor（DTH hammer） is the same as the pneumatic percussion drill. It is a rock drilling tool with a wide range of uses. The following describes the use and maintenance of the down-the-hole hammer.
1. Because the joints and joints of the DTH hammer are all right-handed threads, the dth hammer should always be kept right-handed during drilling.
2. When opening a hole, the down-the-hole hammer should use the smallest impact and propulsion force to make the drill bit enter the rock steadily.
3. It is very important to match the propulsion force with the weight of the drill. The thrust of the propeller must change with the weight of the drill.
4. The rotating speed usually adopted by the dth hammer is generally 15-25 rpm. The faster the speed, the faster the drilling speed, but in hard rock, the speed should be reduced to ensure that the drill bit is not excessively worn.
5. Because blockages and cavities may cause sticking, the impactor should be used to blow regularly and the bottom of the hole should be cleaned regularly.
6. During the connecting process, rock debris and various impurities will fall into the dth hammer. Therefore, the threaded end of the loose drill pipe must be covered to ensure that the drill pipe does not stick to rock debris and dust.
7. The reasonable lubrication of the impactor can never be ignored, otherwise it will accelerate the wear of the impactor and even cause damage.
