AI Technical Summary

Problems solved by technology

[0004] The disadvantage of the prior art method is that when the operator is adjusting the various operating parameters, he / she cannot perceive the impact of the adjustment measures on the overall drilling state and the overall cost of drilling
Therefore, it is very difficult to optimize drilling by adjusting the individual absolute values
Adjustment of a single drilling parameter has a positive effect on one target criterion indicating drilling success, but it has a negative impact on other target criteria at the same time
For example, an increase in impact energy speeds up drilling and therefore reduces drilling costs, but unfortunately at the same time the life of the drilling equipment is reduced, which in turn greatly increases drilling costs

Embodiment Construction

[0018] The rock drilling installation shown in FIG. 1 comprises a base 1, a power unit 2 arranged on the base, a control room 3 and in this case three drilling arms 4 which are movable relative to the base. . The free end of each drill arm 4 is provided with a conveying beam 5, and a rock drill 6 is movably arranged in the conveying beam. The rock drill 6 , the delivery beam 5 and the drill boom 4 form an assembly referred to herein as the drilling assembly 7 . For the sake of clarity, FIG. 1 does not show other auxiliary equipment required for drilling, such as devices associated with the exchange of drill rods 8 and drill bits 9 . The rock drilling rig also includes a control unit 10 arranged on the support 1 , preferably connected in a control room with the device for controlling the rock drilling rig. The control unit 10 receives via lines 11 from a sensor 11 arranged in the drilling assembly 7 measured data concerning, for example, percussion pressure, rotational pressu...

Abstract

A method and a control system for controlling rock drilling. A control unit of a rock drilling apparatus is provided with one or more control modes, each determining the drilling variables to be measured, their threshold values and the operating principles according to which the operating parameters of drilling are controlled to achieve a desired control criterion.

Description

technical field [0001] The present invention relates to a method of controlling rock drilling, the method comprising drilling rock with a rock drilling apparatus comprising a base, a delivery beam, a rock drill movable relative to the delivery beam and means for controlling A control apparatus for rock drilling, the method further comprising providing a memory of a control unit with default setting data for drilling, measuring operation of the apparatus during drilling, and adjusting operating parameters of the drilling to achieve the required control operation . [0002] The invention also relates to a control system for a rock drilling installation comprising a stand, a delivery beam, a rock drill movable relative to the delivery beam, a control unit with a user interface for controlling the drilling and At least one sensor for measuring the drilling operation. [0003] Rock drilling employs a rock drilling apparatus that includes a base, a delivery beam and a rock drill t...
