Assessing and estimating mine reserves form the foundation for studies
such as mine design, mineability, or mining valuation. As foremost mining
consultants, John T. Boyd Company (BOYD) utilizes the latest geologic
and mine planning software for three-dimensional mine modeling and mine
State of the Art Software
- Maptek - VulcanTM
- Other In-House
Example Computer Modeling Projects Include (client name withheld):
- Conducted an independent analysis of remaining
Borax reserves at an operation in California using the Vulcan modeling
software. Our assignment included:
- Development of an accurate and reliable geologic
model for future mining projections.
- Delineation of ore grade and mineralogic haloes.
- Determination of data variability and optimal
drill grid selections for future development.
- Prepared an independent assessment of the remaining
reserve base of a large multiple-seam coal deposit in Kalimantan, Indonesia.
Scope of work included:
- Supervised exploration of the deposit, compiled
and interpreted geologic and geotechnical data.
- Developed a detailed geologic model, reserve
estimates, and mining feasibility utilizing Vulcan software.
- Provided detailed maps and reserve tabulations
to our client.
- Developed a geologic model and reserve base estimate
of an anthracite deposit in eastern Pennsylvania. The steeply dipping
beds in an asymmetrical syncline deemed it necessary to block model
the reserve using Vulcan software. The developed geology and reserve
model were integrated into a comprehensive mine plan for the deposit.
The utilization of GIS can be found everywhere including mine resource
management, asset management, environmental impact assessments, mapping,
sales, and marketing. Boyds GIS staff performs technical data analysis
or database creation. We produce 3D terrain modeling, professional maps,
analysis reports, and customized web-based GIS applications.
Example GIS related projects by Boyd include:
- Engaged the use of GIS to delineate and identify
existing mineral and coal port facilities situated along the Kanawha
River. Developed a database using public information on port facilities
and digital topographic mapping. Applied graphic output and attribute
data to assess potential inter-model transport facilities associated
with new mine development.
- Retained by financial institution to graphically
identify coal reserve holdings of a major coal operator throughout the
continental United States. Utilized supplied lease and fee ownership
information to establish the coal holdings of the operator in an attribute
database (GIS format). This database was then assimilated with public
geographic data to facilitate desired mapping capabilities, whereby
ownership was graphically represented in over ten (10) states.
- Assessed the economic feasibility of a proposed
underground mine employing GIS database management. Utilized existing
public domain database information (topographic mapping, digital elevation
model, Orthorectified aerial photography,) client prepared mine plans
and supporting database information to isolate economic cost centers.
Conducted multiple scenario analyses to evaluate alternative facility
layouts, overland belt conveyor corridors, and refused disposal alternatives.
In addition, performed an analysis to assess projected subsidence liability
risk relating to private structures, major pipelines, railroads, agriculture
production, highways and public water supplies. Results of analysis
used to address and modify projected economic variables included in
the project feasibility study.
- Provided expert witness services associated with
litigation. Assimilated extensive public, client, and contract engineering
expert databases to evaluate historical environmental and reclamation
activities at a lignite mining operation. Applied GIS database management
to assess historical environmental practices and policies used by mining
- Completed an evaluation of coal reserves within
a modified highway right-of-way using GIS incorporating both public
database and developed information. Emergency corrective action needed
to repair landslide damage to state highway. Needed repairs resulting
in the condemnation of private lands containing coal resources. Consolidated
supporting data relating to property ownership, highway designs, digital
elevation models (topographic mapping), and coal seam information into
GIS format resulting in the quantification of coal reserves affected
- Provided consulting services to a major coal operator
in assessing potential liability exposure resulting from mine subsidence
from over one hundred years of mining. Investigated extensive areal
coal extraction in multiple coal seams. Developed a comprehensive GIS
database of historical mine maps with supporting attribute files describing
variable extraction practices (entry widths, secondary recovery, pillar
size, etc.), projected subsidence profiles, assigned subsidence probability,
and local and regional real estate valuations. Incorporated available
public GIS data relating digital topographic mapping, orthorectified
aerial photography, and land use mapping in to the project GIS to evaluate
