Cost-Effectiveness of Dust Controls Used on Unpaved Haul Roads. Volume 2. Data

摘要

The basic objective of the project was to determine the cost-effectiveness of dust controls used on unpaved mine haul roads. Field testing was conducted at three surface coal mines (two in Wyoming, one in southern Illinois) for a total of 20 weeks. The highest control efficiency measured for a chemical dust suppressant, 82 pct, was for calcium chloride 2 weeks after application. Chemical dust suppressants (primarily salts and lignons) can be shown to be more cost-effective than watering under some conditions. Volume II contains basic data.
