Design a modern and professional front cover for a technical book titled "SAP S/4HANA Plant Maintenance Guidance Book". The book is targeted at professionals in the coal mining sector, including engineers, planners, department heads, managers, group leaders, mechanics, plant admin officers, and technical officers. The design should reflect themes of technology, industrial operations, and mining, with a clean, minimalist layout. Incorporate visual elements such as mining equipment (e.g., excavators, dump trucks, conveyor belts), digital schematics, or system interfaces that subtly reference SAP systems. Use a modern color palette (e.g., dark blues, greys, and accents of yellow or orange to symbolize industrial safety and energy). Include the full title prominently on the cover and optionally add a subtitle: "A Practical Guide for Plant Maintenance in Coal Mining Operations Using SAP S/4HANA". The cover should be sized for A4 format and convey clarity, reliability, and expertise.
