Face ventilation system for coal mines

Patent ·
OSTI ID:5494840
A coal mine ventilation system which is described insures proper ventilation near the working area. The basis system employs a mining machine on which is mounted a panel on a movable frame, a conventional line curtain fixed to the mine floor and roof and located adjacent to the panel, and an air control fluid spray system. Fluid sprays may be mounted on the machine opposite the panel to promote airflow towards the mining face. Additional sprays may be mounted on the machine panel to provide an effective barrier between that panel and the fixed line curtain.
