Apogee Coal Company, DBA Arch of West Virginia, faced the challenge of drilling and blasting over one million cubic yards of high temperature overburden at its Ruffner surface operation near Logan, West Virginia. The overburden was removed above the Upper Five Block seam that was previously deep mined, abandoned, and later engulfed by fire. Borehole temperatures were measured above 700 F. This paper presents the development, adaptation, and execution of a working blast plan. The plan specifies products, temperature and exposure time limits, and hole loading procedures. Previous blasting guidelines are reviewed along with test data on selected products. Problems that were encountered are discussed and a pictorial history of the project is presented.
