Jharia Coalfield (JCF) in India has one of the
densest congregations of surface–subsurface coal fires in
the world. Evaluation of spatial dynamics and trend of coal
fires propagation through ASTER thermal data has indicated
that the magnitude of coal fires in JCF has been
fluctuated with time from 2000 to 2009. The area located
around western, eastern and southeastern parts of the JCF
covering Shatabdi opencast, Barora; Sijua opencast; Godhar
colliery, Kusunda; Bokapahari; Kujama; and Lodna is
under intense coal fire. From 2000 to 2004, spatial extent of
coal fire has shown a minor decrease of 6.74 % and then
shows a substantial increase of 11.93 % between 2004 and
2009. Systematic analysis of the results has revealed that
the movement of coal fire in JCF is structurally controlled.
Propagation of the coal fires has been observed in Kustor,
Bastacolla and Lodna collieries, and fire appears to be
spreading along the strike of coal seams toward Jharia
Township. |
