The bill amends the Code of West Virginia regarding the ventilation requirements for underground coal mines. It establishes that in areas where coal is being cut, mined, drilled for blasting, or loaded, a minimum ventilation of 3,000 cubic feet of air per minute is required. This is in addition to the existing requirement that the quantity of air passing through the last open crosscut between the intake and return must not be less than 9,000 cubic feet per minute. The bill emphasizes the importance of maintaining adequate airflow to dilute and carry away harmful gases, ensuring the safety of miners.

Furthermore, the bill outlines various provisions related to the maintenance of ventilation systems, including the use of flame-resistant materials for brattice cloth, the necessity of repairing damaged ventilation devices immediately, and the requirement for a system of bleeder openings to prevent gas accumulation in abandoned areas. It also specifies that production activities must cease during the installation of ventilation devices and that operators must ensure the air quality meets specific standards. Overall, the bill aims to enhance safety measures in underground mining operations by reinforcing ventilation standards.
