2019-8-31 “My instruments transform air speed to electrical currents, these mining companies use a telemetry system called SCADA which measures the standard output of airflow,” he said. Safdy was established in 1990, manufacturing the solid-state air flow systems used underground to help monitor ventilation for South African mines; which is so crucial for a healthy environment. SAFDY solid-state airflow sensors were originally designed for the South African diamond and coal mining

2012-8-29 Instruments such as the vane anemometer measure average speed in only one direction. Unless the anemometer is properly aligned with the direction of the airflow, the resultant air speed values will not be accurate. Uultrasonic anemometers have been designed for measuring airflow velocities in three-dimensional space.

2020-3-24 Ultimately, the determination of the amount of airflow required for an underground mining operation or other sub-surface facility can depend on several factors, including the equipment fleet, ambient temperature, rock type, mining method and airway type (or use). Obtaining a universal, repeatable protocol for determining airflow quantities

1999-1-25 Common instruments of this type are Davis', or Taylor's Biram type anemometer, or Airflow Development's model AM5000. Both Taylor and Davis are widely used in U.S. mining industry but unfortunately, Taylor is no longer available. Just like its counterpart in U.S., AM5000, which is widely used in the Canadian mining industry, is also no longer available.

2018-11-10 Airflow in the mining face can be treated as low-density homogeneous fluid, and therefore, the friction between airflow and drum blades can be approximated to 0. As shown in Fig. 1 , the turbulent airflow from coal cutting (TACC) was migrated along the normal direction and tangential direction of drum blade and the axial direction of the drum ...

2016-1-1 The results indicate that an airflow velocity in the range of 1–2 m/s is the ideal velocity in order to provide a stress/strain free climate and also guarantee thermal comfort for the workers. Therefore, an optimal airflow velocity of 1.5 m/s for the miners' thermal comfort is suggested.
