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.
