Since any mineral deposit is unique, it requires a
particular mine layout and adaptation of the proven exploitation
methods as well as a fine tuning of subsurface infrastructure systems
before starting a mining project. Inclination, spatial distribution of
areas with different thicknesses and grades influence the efficiency
of conventional mining. Therefore, an optimised mine layout is one
key item for the overall efficiency of the ore extraction.
ERCOSPLAN
GROUP OF COMPANIES
provides consulting and planning services to
support the costumer during any stage of the mining project,
beginning with the first concepts for new
operations,
followed by design and method studies for
debottlenecking and/or extension for running operations
and
finally up to the mine closure and site
reclamation.
The high standard of services is
guaranteed by well experienced project teams of mining engineers,
geotechnical and civil engineers for shaft and underground
constructions and even by the in-house cooperation with geologists,
rock mechanical specialists as well as process engineers to consider
the broad interactions of the natural resource up to the final
product.
Starting with a mine layout and
mining method engineering, both tailor-made, regarding the deposit‘s
particular geology as well as the hydrogeological and rock mechanical
limitations of underground extraction, the service comes up with a
mine design optimised for maximum production capacity and minimum
operation cost.

An important topic in our
service are mine safety concepts based on risk assessment of any
realistic impact and completed by the elaboration of prevention
strategies which are practicable under the industrial scale of
operation.
The extraction technology and the equipment
selection for mine transport, mine ventilation and services follow the
national and/or international standards of our clients, considering
the global market and the industrial experience in mine practise. Both are
detailed stepwise during the basic and detail engineering phase.
 Backfilling
of salt and potash mines whether during underground extraction or
after production shut-down is one of our focal points. Driven by the
long-term practise of slurry backfill operations in the Central German
potash industry we provide excellent know-how for backfilling of
processing residues and re-use of industrial waste or the combination
of both.
Beside traditional planning
tools our engineers and computer specialists use recent planning
software such as AutoCAD, INVENTOR and other software in co-operation
with our R&D partners.
