This paper presents a theoretical investigation of the cross sections for dissociative electron attachment and dissociative excitation processes in vibrationally excited CH radicals induced by electron impact. Resonant electron-CH collisions are analyzed using the ab initio $\mathrm{R}$-matrix method, while nuclear dynamics are explored within the local complex potential framework. A comprehensive set of vibrationally resolved cross sections and rate coefficients is provided for both the ground and first excited electronic states of the CH molecule. These findings contribute to a better understanding of the kinetics of nonequilibrium systems containing CH molecules with applications in plasma technologies for ${\mathrm{CO}}_2$ reduction, combustion processes, and various astrophysical contexts.
