Before 5:00 pm, Bryan Cabell, Belt Examiner, finds belt alignment problem; His attempts to realign unsuccessful, Cabell calls for assistance. Belt is shut down 5:05 p.m. to avoid damage to belt material.
Cabell reports smoke to longwall headgate; Cabell sees smoke increasing in intensity and calls again for help. First AMS Alert and Alarm signals occur 5:14 p.m. for Sensor First AMS alert and alarm signals 5:14 p.m.
Cabell calling for Fred Horton. Brown first answers pager phone at 5:14 p.m. and Horton joins call. Alert and alarm signals for Sensor 81 occur at 5:16 p.m First AMS alert and alarm signals 5:14 p.m.
Cabell is on phone with Horton when Callaway and Rose arrive at drive at 5:18 p.m. Flames are visible in fire area. Three men begin fighting fire, but only fire extinguishers could be used in the attempt. First AMS alert and alarm signals 5:14 p.m.
Cabell has asked Brown to evacuate 2 Section. Brown begins to call, then sets off warning strobe light to gain attention. First AMS alert and alarm signals 5:14 p.m.
Brown shuts off belts at 5:39 p.m. Order to evacuate issued by Horton minutes later at 5:42 p.m. after Plumley calls Brown to find out why belts are stopped. First AMS alert and alarm signals 5:14 p.m. First notification to evacuate 5:42 p.m.
Plumley assembles crew and boards mantrip. Crew members are not aware of severity of the fire. First AMS alert and alarm signals 5:14 p.m. First notification to evacuate 5:42 p.m.
Mantrip hits thick smoke in primary escapeway and crew must abandon vehicle. Miners begin donning SCSRs. Miners must now walk through smoke to escape. First AMS alert and alarm signals 5:14 p.m. First notification to evacuate 5:42 p.m. 9
Ten miners find door between primary escapeway and belt (alternate escapeway) and begin moving to fresh air. First AMS alert and alarm signals 5:14 p.m. First notification to evacuate 5:42 p.m. 10 miners reach fresh air 9
Crew members Don Bragg and Elvis Hatfield are discovered missing from the 2 Section crew. Three miners return to smoke-filled intake to begin search to no avail First AMS alert and alarm signals 5:14 p.m. First notification to evacuate 5:42 p.m. 7 miners wait in fresh air 9
Ten crew members resume evacuation out alternate escapeway First AMS alert and alarm signals 5:14 p.m. First notification to evacuate 5:42 p.m. 10 miners continue evacuation in fresh air 9
First AMS alert and alarm signals 5:14 p.m Longwall section loses power. Crew members decide to leave section and begin to move to intake. First notification to evacuate 5:42 p.m. 10 miners continue evacuation in fresh air 9
Ten members of the 2 Section crew arrive outby the fire area at approximately 6:13 p.m First AMS alert and alarm signals 5:14 p.m. First notification to evacuate 5:42 p.m. 9
ACCIDENT INVESTIGATION CONCLUSIONS
The fire occurred as a result of frictional heating when the longwall belt became misaligned in the 9 Headgate longwall belt takeup storage unit; This frictional heating ignited accumulated combustible materials and the belt; The lack of a fire suppression system allowed the fire to spread; The lack of water compromised fire fighting activities; The lack of separation between the No. 7 Belt entry and the primary escapeway for 2 Section allowed smoke and CO to inundate the primary escapeway;
CONCLUSIONS (cont.) Examinations of the mine were inadequate and failed to identify obvious hazardous conditions; Examinations of safety systems failed to identify deficiencies which contributed to the severity and extent of the mine fire; The response to AMS alarm signals was not appropriate; Miners were not evacuated when the fire presented an imminent danger; Escapeways were not properly marked and escapeway drills were not properly conducted;
CONCLUSIONS (cont.) The 2 Section was using belt air to ventilate the working section without an approved change to the ventilation plan and without implementing required additional safety measures; Adequate training was not provided for personnel responsible for installing and maintaining the AMS; Adequate training was not provided for personnel responsible for responding to AMS signals.
