rotatsioonpuurimissüsteemis

rotatsioonpuurimissüsteemis is a drilling method used in various industries, particularly in civil engineering and mining. It combines the principles of rotary drilling with a percussive action, allowing for efficient penetration of hard and fractured rock formations. The system typically involves a down-the-hole hammer or a top-hammer drill rig that imparts a rapid series of blows to the drill bit while simultaneously rotating it. This dual action effectively breaks up the rock and clears the borehole of cuttings.

The rotation ensures that the hammer blows are distributed evenly across the rock face, preventing the bit from getting stuck. The percussive force shatters the rock, and the rotation grinds the broken material into smaller pieces. These cuttings are then flushed out of the borehole by a drilling fluid, such as water or air. The drilling fluid also helps to cool the drill bit and the hammer, extending their lifespan.

rotatsioonpuurimissüsteemis can achieve high penetration rates, even in challenging geological conditions. It is commonly employed for drilling blast holes in quarries, tunnels, and construction sites, as well as for installing anchors and piles. The system's effectiveness is dependent on factors such as the rock type, the size of the drill bit, the power of the hammer, and the pressure of the drilling fluid. Different types of rotatsioonpuurimissüsteemis exist, varying in their power source and specific design features to suit diverse drilling applications.
