Mine managers are responsible for surveying and managing mine ventilation systems using handy tools like mining anemometers. A mining anemometer, just one of the tools that mine managers depend on to protect their teams, is used in underground mining operations to measure the volume of air that is entering and exiting a mine. Using a mining anemometer ensures that there is enough airflow in the mine to prevent dangerous gases from accumulating, and is one way that mine managers measure and evaluate the mine’s ventilation system in order to maximize efficiency and plan for future systems. In addition to utilizing a mining anemometer to measure air flow, mine managers also employ tracer gas, to measure the resistance of individual airways in a mine, an aneroid barometer to determine pressure loss, and mine ventilation simulations to help select ventilation equipment. All of these methods work toward a common goal, keeping mine workers safe and protected every day that they are on the job. Weight: 280.95 Grams, (10.87 Dwt).
