Abstract:

Purpose. To develop the tools for technogenic gas deposits survey in the undermined coal-bearing rock massif.

Methodology. Authors have determined the rock-mechanical state and permeability of rock in the undermined coal-bearing massif under triaxial loading by means of numerical methods on the base of the parameters obtained during testing the samples of these species on uniaxial compression with application of the hypothesis of equivalence triaxial and uniaxial stress state.

Findings. Rock-mechanical state and gas saturation of a rock massif characterize unambiguously the spatial and reservoir parameters of technogenic gas deposits. The analysis of an undermined massif concerning the formation of the gas deposit and the assessment of its spatial and reservoir parameters can be performed by four characteristic points by means of the mathematical model describing the state and behavior of the massif with a specific structure.

Originality. Using the compaction threshold as a parameter characterizing the shell of a technogenic gas deposit we are able to register the uncontrolled flows of methane between the layers of the deposit or to the surface. The part of rock massif within the rock shell characterized by the compaction threshold can be considered a technogenic gas deposit.

Practical value. We can estimate the expedience of use of operating and abandoned mines as gas reservoirs, and search and substantiate the ways of gas production.
