standardization of OPC interfaces for SCADA interoperability, highlighting its importance for multi-platform environments. 2.4 Advanced Analytics and Machine Learning The accumulation of integrated, high-resolution drilling data has opened opportunities for advanced analytics and machine learning. A growing body of research focuses on predicting drilling performance, optimizing bit selection, estimating ground hardness, and detecting anomalies indicative of equipment degradation or geotechnical variability. Although standardized benchmarking methodologies are still evolving, energy-intensity-based models have demonstrated potential for improving drill-and-blast alignment and reducing comminution energy consumption [3], [9]. These approaches align with Mining 4.0 frameworks that seek to transform raw telemetry into predictive and prescriptive intelligence. 2.5 Digital Decision Support and Artificial Intelligence Beyond analytics, recent trends emphasize the integration of artificial intelligence (AI) into operational decision support systems. Conversational AI, natural language querying, and augmented analytics platforms facilitate rapid access to operational intelligence for technical and managerial stakeholders. AI-based dashboards and virtual assistants enable drilling supervisors to query performance indicators, investigate anomalies, and receive proactive recommendations without extensive statistical expertise. Automation platforms such as n8n [10] and AI-driven workflow engines facilitate the orchestration of industrial data pipelines and conversational analytics. However, most implementations remain at early maturity levels, with limited large-scale case studies demonstrating full integration of AI into operational drilling environments.
