Geological and Geotechnical Engineering Back |
Geological Engineering
Increase mine capacity, lower grades, changing regulatory climates, depleted low-cost reserves, and water create many challenges that threaten operating cost or compromise safety. Imagination, knowledge of the character and make-up of rock bodies, state-of-the-art analytical and field tools, and solid production experience allow WEIR to help clients solve their most difficult ground problems at either the feasibility stage or mine operations stage.
Geotechnical Engineering
The mining industry requires
specialized geotechnical engineering analyses and design. WEIR has and will
provide unique and cost effective geotechnical services to the mining industry.
WEIR can provide these services throughout the life of the mine, from conceptual
design through reclamation and closure.
Subsidence Engineering
The mine subsidence services of WEIR fall into two primary categories. The
first is the evaluation and minimization of subsidence associated with active
underground mining, the second is the analysis and mitigation of subsidence
associated with abandoned mines.
Active mine subsidence prediction is undertaken by WEIR utilizing numerous complementary modeling programs. The subsidence analysis is commonly conducted in conjunction with the pillar design and strata control program for a mine.
Mine subsidence as a result of the failure of abandoned mines utilizes some
of the same predictive tools as active mine modeling except that the time
constant, for when an event is going to occur, is highly variable. The majority
of the modeling task is focused on ranking the potential for subsidence to
occur and the magnitude of possible displacements. WEIR also evaluates structures
to determine if they have been impacted by subsidence.
