A highwall measuring approx 150' long, 180' high, & 75' wide collapsed resulting in fatal injuries to 2 miners that were working beneath the highwall. One was operating an excavator & the other was operating a bulldozer. Examination of the remaining highwall indicates the highwall failure originated at the toe of the columnar section above the Pittsburgh Big Vein coal seam.
