Today, DTH drilling rig manufacturers take you down-the-hole drill in how to solve common problems in, drill are often used to cut rock, rock is a very strong, very smooth surface, often due to the rock itself caused rig running drill and drill, so how do we avoid this situation?
Because bit shock Assembly diameter greater than the diameter of the drill rod, length and longer bit with help from far distance of the soldering, and Rod a certain degree of flexibility, so on the rocks in irregular cutting for prone to "run drills" phenomenon, is the axis of the rock drill. In this case if you continue drilling will cause the drill Rod bending, or even "don't drill" phenomenon, causes the drill to not work, and may also result in serious damage to the rig itself. For this problem to be addressed, according to drill carefully studied the works designed a drill enabling locators mounted on the front of the rig it on both legs. Through the use of proven, positioned well, "run drills" a good solution to the phenomenon.
