Type of Report:  Final Report

 

Abstract:

 

Historical perspective, chronology of fire-related events, and observations of

temperature and thermal conditions over 20 years since fire was discovered. 

Examination of complex interrelationships between  mining, geologic structure

and current mine pool elevations.  Examination led to identification of

boundaries expected to prohibit spread of fire and resulting region to which

fire could conceivably spread if left unimpeded for a long term.  Composition

and integrity of rock strata above and between individual mine workings

(ventilation / transmission / potential fire control options). Results of

airborne thermal imagery/evaluation of mine.

Abstract:

 

Report presents results of study of Centralia Mine Fire during 12/81-3/83. 

Activities consist of review of data and background infofmation on the fire and

previously attempted control methods; review of geology, mining, and hydrology

in area; evaluation of physical character of overburden and identification of

thermal effects; ventilation study of mine workings; and review of proven

experimental methods for containing and extinguishing underground mining fires. 

The basic findings of the study are provided in this report.

Type of Report:  Volume 2

 

Abstract:

 

Report presents the study of temperature and gas data; definition of fire

conditions; origin of fire zones; types of fuel being consumed; location and

extent of active fire zones; and degree which other zones receive heat and gases

from active zones.  Report identifies ventilation patterns; potential sources of

ventilation; rates of air flow; and secondary processes to ventilation flow. 

Information is provided relative to the determination of the recent projected

progression of the fire.
