ventilation at coal mines

  • Underground Mine Ventilation Technical Aspects of

    3. Ventilation of underground mines. Underground mines of all sizes require a formal, planned ventilation system to deliver fresh air to all working places. Mine ventilation is the process of supplying sufficient fresh air to the U/G workings to achieve these purposes, ensuring proper distribution & use of the air, and controlling the return to surface of contaminated air.

  • Ventilation Basic Mining Process/Terminology

    Ventilation. Good quality air has to be provided for personnel to breath, to dilute both natural and introduced (e.g. diesel exhaust) gases, to dilute or carry away dust and to provide cooling for personnel and machinery. A small quantity of air may flow through mine workings naturally but this would be insufficient and uncontrolled and therefore it is necessary to provide a

    E ffective management of airflow through underground mines is essential for the safety of mineworkers and for the efficiency of operations. Breathing in dust particles or a toxic gas such as carbon monoxide can have lifelong health consequences, and in some cases just a few seconds of exposure can be dangerous. Modern ventilation systems employ a network of shafts, raises and adits, combined

    Overview of mine seals in US coal mines. Seals are widely used in underground US coal mines to isolate mined-out workings, thereby reducing the ventilation load for the mine. With increased longwall panel sizes being realised by current mining equipment, large, mined-out areas of coal mines must be either ventilated or isolated from active workings by mine seals.
