Mathematical Modeling of Hydraulic Fracturing in Coal Seams

  • Published:
Journal of Mining Science Aims and scope

Abstract

Hydraulic fracturing of coal seam is considered as a process of development of discontinuities in rock mass elements due to change in hydrogeomechanical situation on filtration of fluid under pressure. Failure is associated with excess of the effective stresses over the rock tension strength. The problem on filtration and failure of massif is solved by the finite-element method using the procedure of fictitious nodal forces.
