the stageloader/crusher is the most significant source of respirable dust in the headgate area. the breaking action of the crusher on the coal and rock generates large quantities of dust, which can mix with the ventilating airstream and be carried the entire length of the longwall face. in the us, all stageloader/crushers are fully
capacity axial fans used to ventilate underground mines typically generate a flow rate of 150,000 to 300,000 cfm and have a sound power level of lw = 122 to 125 dba, which is equivalent to a reference sound pressure level of 86 to 88 dba at a distance of 100 feet.2 rock crushers (jaw and cone) have
equipment such as belts and belt drives, crushers, screens, ventilation fans, and around semi-stationary mobile equipment including scalers, and face and floor drills. table 2 lists the results of the sound level measurements for both the surface and underground equipment. for convenience, equipment such as screens, cru c figure 3.
the liquid percentage at 1450 0 c can be estimated using the formula. % liquid content (1450 0c) = 3.0 x a+2.25 x f+s. where a=al 2 o, f=fe 2 o 3, s= mgo+k 2 o+na 2 o+so 3 in clinker. the normal range of liquid phase is 22-27%. burnability is a reference value for raw meal indicating how difficult it is to burn.
crushing, etc., generate particulates that then disperse into the air. these partic-ulates come in a wide range of sizes and many remain in the air indefinitely. such dusts often can harm both people and equipment. so, plants should strive to elim-inate or at least minimize dust generation and emission. preventing the generation of dust gener-

the process flowsheet is a conventional cyanide leach-style circuit typically used to process free milling gold ores. the plant incorporates primary jaw crushing, secondary cone crushing, crushed ore product screening and storage in a crushed ore bin. crushed ore is reclaimed from the bin via two belt feeders that feed to a milling circuit.
for system 1 (individual extract fans with background trickle vents in windows) and decentralised system 3 (continuous mechanical extract) installations we use an anemometer and cone to measure the flow rate of each extract fan. for centralised system 3 and system 4 (continuous mechanical supply and extract) we use the same equipment to set the

gold cone filter the patented gold cone filter has allowed many facilities to reduce the number of filters they have to use and change. the innovative cone of filter media expands the usable area of the filter allowing a reduction in the number of filters by at least a third. the design has also led to long filter life with low pressure drop.
