The crack propagation of hydraulic fracturing of coal is actually a fracturing problem of semi-infinite layered media. It is necessary to discover a fundamental solution for layered coal, if the crack propagation of hydraulic fracturing is simulated by finite element or boundary element method.  The relations between the displacements and the stresses on the surface of semi-infinite body are obtained in introducing the infinite boundary conditions. The displacements and stresses in an arbitrary point of the semi-infinite body are easily deduced by using the transfer matrix equation. The results can be degenerated to the classic Mindline’s solution in a semi-infinite body.
