Objective of the paper is to substantiate and implement the
integrated approach aimed at the studies of filtration and mass-transfer
processes within roof rocks of coal seams in the context of their
underground gasification. Integrity of the studies is substantiated by the
use of analytical calculations as well as physical and numerical modeling.
Zones with different permeability have been determined and values of
specific water inflow have been identified basing upon the performed
numerical modeling and involving multicomponent transformations within
roof formation.The research data actuality is in the studies of spatial and
temporal dynamics of rock technogenic rock permeability above
gasification channel depending upon their geological structure which will
favour the substantiation of efficient engineering solutions to control a
process of underground coal gasification under difficult hydrogeological
conditions.
