performance as described before are mining environment and mining engineering. Each component has variables and some variables have sub-variables such:
1. MINING ENGINEERING
Mining engineering is one of quantitative parameter that have to measure in case of mining performance evaluation.
a. Reserve Addition
The additional mine material raw material that produced from proven reserve based on all factors of feasibility study fulfilled.
b. Mining Operation
Mining operation means total area that can be opened for extracting ore material and waste rock and also volume of material produced from ore or
called run off mine ROM. c.
Production and Processing There have several aspects in production and processing that have to
consider such as synchronization of run off mine, processing and total content of mineral.
d. Stockpile
Stockpile regard to stock of ore material which will produce mineral, consist of low level ore and high level ore.
e. Shipping
Shipping will determine the capacity of ship vehicle in volume of composite material.
2. ENVIRONMENT MONITORING
Environment is also one of critical point in mining activity that has been directly infected to environment sustainability and local community
livelihood and indirectly infected to mining company performance. Monitoring of environment around mining area involves the calculation
and evaluation of physical and chemical condition of air quality, water quality and soil quality.
a. Cutting
Cutting determines vegetation area extraction that will use for extracting raw material.
b. Cover Soil Peeling
Cover soil peeling is the next step after cutting which extract the top of soil surface. It consists of peeling for mined new area and hoarding for
mined out area. c.
Sprout Soil Peeling Sprout soil peeling is the next step after cover soil peeling which extract
the next level of soil surface. It consists of peeling for mined new area and hoarding for mined out area
d. Mining Environment
Mining environment determine mine work area which consist of the active, mined out and tailing area.
e. Washing dan Purifying
Washing determines kind of chemical and water for washing and purifying determines tailing volume and processing.
f. Reclamation
Reclamation determines the recovery of mined out area, consist of soil hoarding and regevetation.
g. Air Quality Monitoring
Consist of aspects like sulfur oxide, nitrogen dioxide, etc. h.
Water Quality Monitoring Consist of physical and chemical aspect.
i. Environment Cost Rp
Environment cost is accounted in year or each quarterly.
