MINE STABILITY
SGSI
has supported the minerals extraction industry with rock mechanics
and rock stabilization both on the surface and underground. SGSI
led a program of core and rotary drilling, instrumentation (including
Time Domain Reflectometry), and analysis, including numerical computer
modeling, for the Cove Mine pit slope failure in Nevada. SGSI also
led the pre-mining slope stability and design investigation at Eldorado
Gold's La Colorada mine expansion near Hermosillo, Mexico.

Iron Mountain Mine, CA |
SGSI
personnel have completed numerous ground control studies for coal
and metal mining throughout the U.S. These studies have entailed research,
in situ testing, measurement of ground stress and stress changes,
laboratory geomechnaics testing, down hole logging and core drilling,
and numerical computer simulations. We have also provided conventional
geotechnical services in support of mine infrastructure improvements,
such as mill and concentrator expansions requiring heavy machine foundations,
and ore loading facilities.
SGSI personnel have provided reserves estimates and mine planning
support, using computer programs such as Medsystem and other geologic
software. SGSI offers the latest in computer analysis for underground
and surface mine stability, including finite difference, finite element,
boundary element, and limit equilibrium codes.

Services for Abandoned Mine Remediation
SGSI personnel
have been providing abandoned mine related services since the early
1980s. We have served OSM, the U.S. Forest Service, the U.S. Bureau
of Mines, and many State agencies in issues of acid mine drainage
abatement, instabilities arising from subsidence, highwalls, and
mine waste embankments; and many other environmental and physical
safety issues. Our staff has background in research as well as remediation.
Many of our clients are interested in SGSI's capabilities in rock
excavation and rock blasting.
