2. The many ways mining activities impact biodiversity. Mining affects biodiversity at multiple spatial scales (site, landscape, regional and global) through direct (i.e. mineral extraction) and indirect processes (via industries supporting mining operations, and external stakeholders who gain access to biodiversity-rich areas as the result of mining).
Mine Ventilation Systems One of our most important roles when ventilating an underground mine worker safety: making sure airflow is sufficient in quantity and quality. Mine Water Treatment We have the experience and technical skills to evaluate, design, and build water treatment systems that are tailored to the unique factors of your mine.
Coal Mining Coal can be extracted from the earth either by surface mining or underground mining. Once coal has been extracted, it can be used directly (for heating and industrial processes) or to fuel power plants for electricity. Surface Mining If coal is less than 61 meters (200 feet) underground, it can be extracted through surface mining.
Design of the UPHES plant in the studied underground coal mine. The gross head is 450 mH 2 O, but a net head of 439 mH 2 O is considered (80 m below the current flood level in the reservoir). Below the lower reservoir, some mine voids are kept dry to create extra water storage capacity from a possible pipe burst, so any escaping water ...
Backfilling costs in underground mining operations must be critically examined to identify potential cost savings (Stone 1993). Although paste backfilling is somewhat expensive, it is indispensable for most underground mines as it provides crucial ground support for mine safety and mining operations.
In an underground mine, the feed tends to include more foreign objects than in a surface operation.
