Our cement solution includes a number of raw material management
levels that provide processes and procedures for head office and
operational technical staff.
Level
1
The calculation of the resource, reserves and life of the quarry
allowing you to quantify your mineral resource assets and protecting
your natural capital
Level
2
Maximising the life of the operation by scheduling the raw material
in the long term to meet corporate and operational objectives. For
example, schedules can be produced against multiple targets
including lime saturation factor, silica modulus and aluminium ratio
targets. In addition other targets can be set to reduce contaminants
like MgO and Alkalis. The purpose of schedules is to deliver a
practical, consistent quality of feed to the crusher by reducing the
variability and standard deviation in the raw material from the
quarry.
Level
3
Plant process flow optimisation (PPFO) allows the operation to adapt
to market conditions including a change of product/s specification
and pricing. PPFO permits the quality-controlled raw material from
the quarry to be modelled through the crusher and pre-homogenising
cycles. The introduction of external stockpiles or sweaters allows
the raw feed to be corrected to a very high plant specification
before entering the raw mill. Multiple product opportunities can be
considered by adjusting quarry outputs, alternative additives and
plant targets.
Level
4
Operational Scheduling by linking the quarry and plant. Short term
schedules are generated within the life of quarry schedule so that
the long term objectives can be honoured. The short schedules are
updated with operational survey data and blast hole information to
drive the daily production planning. Information from the plant
(either from LIMS or cross belt analyser) can be used to reconcile
the actual with planned raw material that allows modifications in
the production planning to be made. Real time production planning is
possible using live analytical data, truck dispatch systems with GPS
equipment.
In 2003, 3 out of the 5 largest global cement producers (Lafarge,
Cemex and Italcementi) use Datamine Software in their quarry
planning cycle. In total the Datamine Group has over 35 cement
sites using its software for a range of uses including; databases,
geological modelling, quarry optimisation and long term planning,
quarry design, short term planning, virtual reality and
environmental impact analysis. |
