ELASTOPLASTIC FILTRATION OF LIQUID IN UNSTABLE SEAMSB. Kh. Khuzhaerov, I. E. Shodmonov, E. Ch. Kholiyarov, and A. A. Zokirov UDC 532.546 Equations of elastoplastic filtration of liquid in seams, whose skeleton can fail under large effective stresses, have been derived. On the basis of their numerical solution the influence of the seam instability factor on the filtration characteristics has been established.
