    of water (a process called ‘hydraulic mining’) are used to extract the ore. Placer mining is usually aimed at removing gold from stream sediments and floodplains. Because placer mining often occurs within a streambed, it is an environmentally-destructive type of mining, releasing large quantities of sediment that can impact surface water for several miles downstream of the placer mine. 1.1

    The upper level is used for undercutting the ore zone to initiate caving. The lower production level is used to extract the bulk of the ore through funnel like excavations from the upper level. In the lower level, load haul dumpers collect the broken ore and take it to a crusher before being taken to surface for processing. This type of mining, known as block caving, is a well-established and

  • Process mining Wikipedia

    Process mining is a family of techniques in the field of process management that support the analysis of business processes based on event logs. During process mining, specialized data mining algorithms are applied to event log data in order to identify trends, patterns and details contained in event logs recorded by an information system. Process mining aims to improve process efficiency and

    In underground mining, miners tunnel into the earth’s crust through the kimberlite pipe. Tunnels are constructed on two levels about 25m vertically apart. The upper level is used for undercutting the ore zone to initiate caving. The lower production level is used to extract the bulk of the ore through funnel like excavations from the upper level. In the lower level, load haul dumpers collect the broken ore and take
