WHILE THE OPERATOR WAS DRIVING THE VEHICLE NEXT TO A 40 FOOT-HIGH COAL PILE. THE TRANSMISSION FLUID HOSE PROBABLY DEVELOPED A MAJOR LEAK, SO THE EMPLOYEE PARKED THE SCRAPER NEXT TO THE PILE. IT IS CONJECTURED THAT THE OPERATOR SHUT OFF THE FRONT ENGINE AND WAS MOVING TO SHUT OFF THE REAR ENGINE WHEN A COAL PILE SLIDE OCCURRED. EMPLOYEES FOUND THE REAR ENGINE STILL RUNNING AND EMPLOYEE #1 COMPLETELY BURIED BY COAL. HE WAS FOUND MIDWAY BETWEEN THE FRONT AND REAR ENGINES ON THE SIDE OF THE VEHICLE CLOSEST TO THE COAL PILE. CONTRIBUTING FACTORS TO THE SLIDE INCLUDED PILE UNDERCUTTING AND RAINFALL ON THE PREVIOUS DAY.
