1981 1.4 Objectives The objective of this paper is to present and analyze a methodology developed in Peru for the progressive implementation of tele-operation and autonomy in large-diameter rotary blasthole drills used in surface mining operations. The proposed approach seeks to reduce operator exposure to hazardous conditions, improve drilling process consistency, and enable a new model of human–machine interaction while maintaining human supervision as a central element of the operation. 1.4.1 General Objective: To develop and implement a progressive tele-operation and autonomy model for rotary blasthole drilling that enhances safety, operational efficiency, and the transformation of traditional operating practices in surface mining. (Iversen et al., 2013a) 1.4.2 Specific Objectives: • To reduce operator exposure to high-risk conditions through the gradual physical separation between personnel and the drilling environment. • To increase drilling consistency and repeatability through the application of supervised autonomous functions. • To redefine the operator’s role from direct manual control to supervisory and exception-based management. • To develop the technical and organizational capabilities required for the sustainable adoption of teleoperated and autonomous drilling systems in large-scale mining operations. 2. METHODOLOGY The implementation of tele-operation and autonomy in large-diameter rotary blasthole drilling was addressed through a structured and progressive methodology developed and validated in surface mining operations in Peru. The methodological approach recognizes that successful adoption of these technologies depends not only on technical availability, but on the coherent integration of autonomy frameworks, safe technical architecture, operational readiness, and organizational change management. The proposed methodology was designed to enable a controlled transition from conventional cabinbased operation to remote operation and supervised autonomy, while always maintaining human supervision and prioritizing risk reduction and operational stability. 2.1 General Methodological Framework The methodological framework is based on a progressive transition model that enables the gradual decoupling of the operator’s physical presence from the drilling environment. This framework was designed around the coordinated evolution of three critical dimensions: • System autonomy level, • Operational process maturity, • Workforce readiness and adaptation. Each stage of the model is validated before progressing to the next, ensuring that technical, operational, and human-related risks are identified and managed in a timely manner. This approach prevents abrupt implementations and allows lessons learned to be consolidated at each phase of the transition.
