Abstract (en)
[origin: WO2022139654A1] The present invention relates to a method for optimising at least one drilling parameter during an ongoing drilling process, the drilling being carried out by a percussive drilling machine (105), the drilling machine (105) being set to drill at an operating point, the operating point of the drilling being determined by the setting of a plurality of control parameters.The method comprises determining a first plurality of drilling machine operating points (401a-d; 402b-d; 403c-d; 404a-d), the operating points (401a-d; 402b-d; 403c-d; 404a-d) being set by said plurality of control parameters. Furthermore, percussive drilling is performed at each of said first plurality of operating points (401a-d; 402b-d; 403c-d; 404a-d) and at least one resulting drilling parameter is evaluated for each of the plurality of operating points (401a-d; 402b-d; 403c-d; 404a-d). The method also comprises determining a new plurality of drilling machine operating points (401a-d; 402b-d; 403c-d; 404a-d) to be drilled based on said evaluation, and subsequently drilling the new plurality of drilling machine operating points (401a-d; 402b-d; 403c-d; 404a-d).
