Face ventilation in underground bituminous coal mines
Performance characteristics, efficiency, and operating pressure of jute line-brattice systems were studied under varying underground conditions; various fabric grades and installation methods were used; test results indicate that line-brattice system efficiency is dependent upon method of ventilation, method of installation, porosity of fabric, and size of tight rib area.
