Summary
Professional geologist and engineer with 7 years’ experience across mining exploration and exploitation. My mine geologist & geotechnical skills and experiences include geological collection, validation, interpolate and define the basic 2D & 3D geological & geotechnical model for mine planning, geotechnical open pit, waste dump, hauling road, and other civil project area that related to mining project (geotechnical issues on port area and bearing capacity for building), Hydrogeology testing; Packet Test, Slug Test, Pumping Test to define K, S, Pore Pressure, and others hydrogeology parameters. Moreover, I could create and manage Ground Control Management Plan (GCMP) for mining area to provide a comprehensive management plan that addressing all known issues pertaining to ground control management of mining operation. My previous work experience and leadership roles in both mining company & mining contractors make me an ideal candidate for your company because I could handle mine geotechnical engineer works and manage daily mining operations to controls design vs actual of mining face. I also have IELTS certificate with overall score 6.5. Therefore, i have enriched my knowledge, experiences, and as well made me an International culture person.
