## Abstract

The final rule will allow the use of intake air passing through belt air courses (belt air) to ventilate working sections and areas where mechanized mining equipment is being installed or removed in underground coal mines. The use of belt air, under the conditions set forth in the final rule, will maintain the level of safety, and therefore not reduce protections, currently afforded miners in underground mines while implementing advances in mining technology. The final rule amends existing safety standards for ventilation of underground coal mines. This final rule also amends other standards.
