correo electrónico: jeff.oke@mdeng.ca

El Sr. Jeffrey Oke ofrece pericia en el diseño de soporte para minas subterráneas. Cuenta con experiencia con modelación numérica 3D y particularmente desarrollando modelos calibrados capaces de reproducir la interacción del soporte con la roca masiva más la reacción complete de la roca. Su área de experiencia incluye la colección de datos geotécnicos, análisis e interpretación para la clasificación de la roca y delineación de dominios. En adición el Sr. Oke tiene una compresión geomántica y mecánica de tierra y mecánica de roca. Al momento está completando su doctoral en modelación numérica y emperica con análisis analítico de sistemas de soporte con arcos en minas subterráneas en Queen’s University.

Áreas de Pericia:

  • Modelación Numérica
    • Experiencia significante en capturando la respuesta de sistemas de soporte completas en excavaciones subterráneas.
    • Modelación Numérica 3D y 2D
    • Software de Itasca y RocScience
  • Diseño y verificación de excavaciones subterráneas y taludes en tajos
  • Ingeniera de estabilidad para taludes diseñadas y naturales y evaluación y mitigación  de los mismos
  • Diseño de soporte, evaluación y revisión
  • Caracterización geo mecánica del sitio
