Technological aspects of technogenic disturbance liquidation in the areas of coal-gas deposits development

The objective of this work is to develop the technological
measures for liquidation of technogenic disturbances that have arisen
within the residential areas. Based on the results of geophysical studies, the
causes and factors of Earth’s surface caving occurrence that arose in the
result of natural-technogenic processes activation in underworked massif
and are caused by the soil subsidence under buildings and constructions,
have been determined. The solution of the problem was carried out with
the use of methods for observing the natural pulsed electromagnetic field
of the Earth and electric tomography in the area adjacent to the place of
caving. The conclusions about the possible causes of the caving trough
formation and its further development have been formulated, as well as the
technological scheme for its liquidation have been developed. The
developed new technological scheme allows conducting the effective
liquidation works in conditions of proximity to the residential buildings
and maximally reduces these scopes of works at ecological and protective
measures.
