Abstract:
Purpose. Development of tools for anthropogenic gas fields prospecting in undermined rock massifs.
Methodology. The spatial parameters of anthropogenic gas deposits have been identified by numerical simulation based on the results of uniaxial compression tests of enclosing rocks material.
Findings. We have determined that the anthropogenic deposits located in inhomogeneous layered massifs with different geometric and strength parameters of layers have complex shape, extended along weak layers and compressed along strong ones. The shell of the anthropogenic reservoir which prevents the outflow (inflow) of methane is dedicated to that part of the massif which is characterized by the lowest values of permeability. And it has a clear quantitative description.
Originality. Spatial parameters of the anthropogenic gas fields are uniquely characterized by the geomechanical condition of the undermined massif. To determine these parameters we have proposed the step by step procedure during which the stress-strain state of the rock massif is investigated on the model which is loaded similarly to the sample of rock during its controlled deformation tests in laboratory. This allows us to provide matching of the process studied on the model to the real process.
Practical value. Evaluation of the exploitation prospects of undermined massifs of operating and abandoned mines as reservoirs of gas; search and justifying of decisions on how to extract the gas from such reservoirs.
