INITIAL DRILLING CONTROL METHOD OF ROCK DRILL

摘要

The present invention relates to a method for controlling the operation of the drill to precisely puncture the position when drilling the rock by using a puncher used to drill holes in the rock, it is mounted to the drift (14) In order to prevent the drill from deviating from its original correct position when hitting and rotating the drill hitting the rock, at the beginning of the drilling operation, the impact force is set to a predetermined value rather than the normal value so that the drill only strikes and moves forward and backward. Forming a depth of the hole to a predetermined depth by striking at a small rate and advancing the drift 14 forward and backward; When the drill is inserted into the rock by a predetermined depth, the process is performed to increase the rotational speed and the impact force of the drill by increasing the hydraulic pressure supplied to the drift 14 so that the rotational speed and the impact force of the drill are restored to their normal values. Provides an effect that increases.
