  2. Safety Performance With an understanding that all incidents are preventable, and all tasks can be completed without harm, extra focus, training and improved supervision must occur to reduce the Frequency of incidents. May Safety performance was not acceptable level with one recorded LTI. LTI recorded when a workmen was unreeling a jumbo trailing cable suddenly jumbo roll back and hit on the workman resulting in swelling and multiple injuries. First Aid case reported when a workman was moving the cable bolt drum for align in the pipe in this process his left hand index trapped between cable drum and machine part which caused laceration in left hand index finger . First Aid case reported when a workman was unloading the rock bolt from PC-4 And stacking on the sidewall and another workman which was standing inside the PC and giving rock bolt to him in the process rock bolt hit on the left arm and scratched on the same.

  3. PERSONAL INJURIES

  4. PropertyDamage Frequency of equipment damage and near incidents across May was higher than expected and we see this is an area that needs improvement across the board.

  5. Property Damage

  6. Near Miss/ Incident Comparison

  7. Safety Positives • Action Plan • Continuing delivery of SOPs to all employees.( role specific SOP completion has been targeted to ensure coverage of specific requirements) • To complete SOP coverage for all new employees before release into the work teams. • Safety Tools box talks and campaigns on:- • Heat Exposure and associated illnesses . • Contact with electrical source. • Manual Tag Board management (issues from April have identified gaps in cultural practices compared to SOP requirements). • Continuous awareness of handling and hanging of Trailing cables. • Line of sight remote loader operation and required controls including man holes • Traffic and pedestrian flow changes around the HEMM workshop • 4. Safety tool box talks are being delivered to all employees at start of every each shift. • Reviewing, briefing and enforcement of all SOPs. • Ensuring that supervision is adequate for all employees performing tasks.

  8. Performance Review May was an another positive month for development. • Overall mine performance for May month was 1408.80 meters. • AAC performance 676.97 meters. • RDC performance 731.82 meters. Production Drilling • Production Drilling for this month is 11049.1 meters.

  9. Performance Trend Line Including approved slyping

  10. Development Performance for May Including approved slyping

  11. AAC Development Performance For May

  12. Production Drilling Survey Data Pending Meters

  13. SOLO Performance • Total All In Meters for May = 10122.5 mtrs • Availability vs. Utilization combined was 60.5% vs. 47.5% (Excessive back reaming, bogged Rods as Percussion not used) • Total combined Power Pack Hours = 450hrs • Total combined Percussion Hours = 192hrs • Drilling Utilization = 62% • Completion Rate from Designed Meters was 86.3% • Combined Percussion Rates for Month at 54.6Mtr/per/hr • 803mtrs achieved in 21hrs of Drilling time. • Drilling areas becoming more readily available for Month of Jun

  14. SOLO Drilling Day wise (in meters) SOLO-1 SOLO-2

  15. SOLO Downtime • Site Preparation continued to be a source in Downtime of 11%, still high considering it’s a factor we control. • Daily Service is indicated with maintaining Rig Temperatures down. • Firings attributed to North Side only. • Drifter change out in latter part of Month, Drifter strip down continuing. • Solo 2 Mechanical mainly attributed to Compressor pump issues and Feed Rail dislodgement from BoomSolo also being affected by heat issues in Stopes.

  16. Total Tonnes of Ore and Waste Moved

  17. Haulage Trending Tonnes

  18. Shotcrete Performance

  19. No. of Blasts V/S Millers Sprayed As per Geo-Tech requirement and back log included

  20. Long Round Performance(Including B1 & B2) Pull in meters No. of Blast

  21. B1 Performance Per Blast 3.8

  22. B2 Performance Per Blast

  23. Graph Indicators • This month AAC has achieved 94.97% of our target • Shotcrete machine breakdowns and idle times are high and require additional management focus to increase total Shotcrete placement.-Use of Shotcrete bore holes to be optimised • This month hauling little bit less then pervious month tonnes. • Production Drilling was below from target. • Long round “pull length” slightly below than compare to pervious month, however the overall results must improve to achieve the maximum “pull length” in each and every round blasted. • Additional focus required to expedite consistent development in Block 1.

  24. Improvement Opportunities and Special Focus Areas • To increase the “pull length“ on all rounds (AAC are currently reviewing processes to identify improvement opportunities • Optimising the use of B1 and B2 for longer drill rounds and replacing one boom by split feed boom to utilized in scaling, rock bolting etc.). • Additional works on improving the secondary ventilation (standards and management of vent in headings) • Training of AAC Supervisors re standards- efficiencies and correct cycling. • Standards to be driven to ensure that all “last rounds” are supported without delay. • Cycling of P1 headings and ensuring that they are not missed (maintain focus on daily targets but not at the expense of sacrificing critical headings).

  25. Kaizen Projects

  26. Suitable Tool for Paste Fill Pipe Cleaning There is at times some paste fill line got chocked. So modify the jumbo drill bit to clean them.

  27. Cable Hanger Stand To put cable hanger on one place cable hanger stand fabricated. Stand Cable Hanger

  28. A-Shift Timing 06:25

  29. B-Shift Timing 14:25

  30. C-Shift Timing 22:25

  31. Improvements • Solo-2 has had a number of parts removed to keep Solo1 going due to no Critical Spares on-site. • Additional experienced personnel for the Solo drills have been sourced to support the process. • Continued focus on improving the utilization of equipment. • Chatter Singh has been undertaking multiple training sessions on various equipment's and gaining competency authorisations. • AAC is currently identifying operational training improvement opportunities to support departmental requirements. • Communications between HEMM, OEM’s and AAC regarding maintenance schedule times has improved. • PDI personal’s training started on different equipments. • Scope of work and proposal being compiled for amalgamation of HZL and AAC safety and Training Departments.

  32. Indian Manpower Availability and Absenteeism

  33. AAC Disciplinary Action
