DTH drilling refers to a method where the drilling bit is located at the end of a drill string, below the surface of the ground. This technique is distinguished by the use of high-performance percussion hammers, which are positioned on the drill bit. DTH drilling involves the use of compressed air to deliver rapid impacts, breaking rock into smaller fragments. This method is particularly effective in hard rock formations, making it a preferred choice for mining operations and various drilling applications.
(1) When using the drilling rig to drill, the driver should be placed in the drilling position, so that the front end is against the rock, and the distribution should be careful to let the drilling rig move forward, so that the drill bit touches the rock; When opening the hole, first quietly let the drilling rig drive, when the drill rod is in place in the rock, it is allocated to the full open position.
