Implemented the site Ground Control Management Plan to insure safe and zero-harm mining operations daily. This includes but not limited to – visual inspections of pit walls, berms, dump and stockpile slopes; critical monitoring of mining areas using Slope Stability Radar and prisms.Reviewed pit and dump designs to allow stable structures both during developmentand completion of projects; monitoring of all pits and dumps on a regular basis; reporting of all hazards to pit supervisors and concerned personnel on a timely manner.Performed modelling, data processing and analysis of engineering solutions related to site geotechnical workDeveloped proposals and supervised programs of geotechnical investigationsAssisted the Chief Geotechnical Geologist in development and construction of department annual operation budgets and cost review by ensuring prudent cost control and that operating expenses are within approved budget.Participated in the Performance Management System, ensuring the performance evaluations of self and the subordinates are submitted in a timely manner

Drill and Blast Engineer :Scheduled drill and blast activities to ensure safe, efficient and continuous mining operations Produced drill designs and loading sheets for production blasting, wall control and secondary blasting Produced delay plans for both non-electronic and electronic blasting considering vibration control, minimizing dilution and achieving efficient fragmentation Reconciled actual blasting results against designed parameters for improvement of drill and blast activities Analyze Underground Workings in relation to mining activities Did minor pit redesigns in order to achieve operational drill and blast activitiesPrepared three-month Drill and Blast requirementsPerformed other drill and blast functions to ensure that mining plans materialize Performed other technical functions to ensure safe and efficient operations Assisted the Senior Mine Engineers and Mine Engineering Superintendent in preparing mine plans and mine designs Mine Production Engineer (short term mine planner)Constructed realistic weekly production schedules consistent with monthly targets considering the following - available mining areas, available dumping locations (ARD management included), equipment availabilities and productivities, process plant requirements, grade control drilling, presence of underground workings, and any other constraints. Identified areas of scheduling difficulties and ensure these are addressed. Monitored development of dumps in accordance to design, safety, and environmental standards Performed workplace safety and environmental inspections to identify and address hazards Constructed/modified pit and dump designs to adhere to safe design criteria (berm widths, batter intervals, batter slopes, ramp widths, ramp gradients) while also considering operational efficiency, traffic, and drainage management.
