6. Intense coordination with Organization Leader/direct supervisor for client requirement.
7. Review seiswatch parameter related Open Stope mining activity and trigger rate activity (with seismic distribution).
8. Provide BG seismic update notification for blasting and update status of seismic protocol, seismic event rate at concern area.
9. Review Early warning lighting system for BG production area.
10. Review seismic condition outside & inside cave lines or caving BG and database seismic closure and hydrofract closure time, the performance of the seismic activity rate tracker.
11. Review the exclusion zone & exclusion times into working places after production blasts for BG.
12. Re-assess the required configuration, the sensitivity, the location accuracy of seismic network & the suitability of currently employed sensors.
13. Review Seismic Moment Tensor Inversion (SMTI) BG Mines- analysis for Mw>0.5, PPV analysis related mining (blasting) impact to facilities accommodation.
14. Review monitoring system function and availability monitoring devices per area concern (road access closure and mining infrastructure).
15. Monitor & analyze trend of deformation monitoring at Operation Support area and conduct pre[1]checklist data.
16. Review system troubleshoot related to deformation monitoring device connection, software upgrade and license.
17. Monitor & analyze TARP of rainfall station for road access closure and mining infrastructure.
18. Evaluate alarm & any issue on radar data, review system health check & availability monitoring devices for all monitoring system, review system troubleshoot related to monitoring device connection, software upgrade and license and review all inventory of monitoring device - in the case for replacement or calibration.
19. Review daily monitoring which associated to geotechnical hazard, rainfall, and Open Stope mining).
20. Undertake collaboration on data analysis, interpretation & inform concern area and recommendation from monitoring data to client.
