1396 5. Construction and Cleaning of Garland Drains: New garland drains are constructed around OB dumps and mine pits, while existing ones are cleaned and deepened to effectively channel surface runoff away from working areas, illustrated in Figure 9. 6. Repairing Old Benches in Dumps: Existing benches are reinforced to prevent collapse and to facilitate proper water flow through designed pathways. 7. Table Top Water Coursing: Measures are taken to ensure that rainwater flows smoothly over dump tops without causing erosion, through proper grading and water course channels.

Civil and Electrical Works: Essential civil infrastructure such as retaining wall, culverts, and parapets are constructed or repaired for slope stabilization and erosion control and is shown in Figure 10. Electrical installations, particularly related to dewatering pumps and mine lighting, are inspected and upgraded for safe operation in wet conditions. Figure 10: Construction of Retaining Wall.
