ti First Quarter 1995 ENGINEERING INSPECTION SOMERSET MINING COMPANY EAST YARD GOB DISPOSAL PILE On March 27, 1995, I performed a visual inspection of the east yard gob disposal area at Somerset Mining Company's, Somerset Mine. Both Bear Coal Company and Somerset Mining Company have approval to dispose of coal mine waste in the gob pile. Page 2.05-19ii, dated 12-10-92, of Somerset Mining Company's approved permit document includes the requirement to inspect the coal mine waste pile for stability quarterly. The inspection is to be performed by a registered engineer or other qualified professional specialist experienced in construction of earth and rockfill embankments. The quarterly inspection report is to note the volume of waste material placed in the pile since the last inspection. The gob disposal area was dry. Nothing was observed during the inspection that would indicate the pile has a potential for failure. Compaction tests were performed for fourth quarter 1993, second quarter 1994, and fourth quarter 1994. Gob material has consistently passed compaction tests. Compaction tests will be scheduled during the second quarter 1995. Somerset hauled approximately 942 cubic yards of material to the gob pile during the quarter. Bear Coal Company did not haul any material to the gob pile during the quarter. A failure of the pile would probably not be a hazard to human life. The pile is located above a large flat bench referred to as the east yard. The bench is 80' to 100' wide directly below the pile. If the coal mine waste pile failed, it would very likely be contained in the east yard. The overland conveyor and conveyor drive on the bench below the pile might be damaged by a failure of the pile. _,:-R°~ ' •;' :: C.
