comparison of data mining methods for the signal detectionthere are several different proposed data mining methods for the postmarketing surveillance of drug safety. adverse events are often classified into a hierarchical structure. our objective was to compare the performance of several of these different data mining methods for adverse drug events data wtautona mine worlds deepest mine ~ incredipediathe tautona mine or western deep no.3 shaft, located in south africa, is the deepest g mine in the world with miners working 2.4 miles below the earths surface. known as one of the most efficient mining processes, 5600 miners roam through 500 miles of tunnels removing the g containing ore. the tautona mine exists within the west witts area slightly south west of johannesburg in the north3. mineral and rock mining maristas checkpointtechnology applications and basic decisions about design and mining method rest on considerations like the type of ore being mined, composition of surrounding rock, shape and orientation of the ore deposit, geologic features underground, and the first mine declared the deepest in the world was also tautona when it was at 3,581 metres.mining weekly tautona on r1,6bn expansion coursesep 24, 04· lazare points out that this method of development has proved itself in terms of productivity and safety. it was a departure from this development technique that saw tautona experiencing four fatalg extraction g extraction refers to the processes required to extract g from its ores.this may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. g mining from alluvium ores was once achieved by techniques associated with placer mining such as simple g panning and sluicing, resulting in direct recovery ofabout chronus mining inc.chronus mining inc. was first established in august 04 by founder, david fairbank, after his huge success working in the tautona (from 88) (closed) g mine. with increasing technological developments around this time, david reached out to dr. albert finch, a talented machine engineer who developed the early g7 drill, which
