Based on Bogoliubov's chain of equations the kinetic theory of rapid particles in crystal is developed. For one-particle distribution function under iteraction of particles with thermal oscillations and valent electrons a local kinetic equation is obtained. With the account of the explicit form of the collision term in the kinetic equation the basic characteristic of a subsystem of particles in the dechannelling problem – diffusion function $B(\varepsilon_\perp)$ in the space of transversal energies is found. It is shown that the functional dependence provided by $B(\varepsilon_\perp)$ is different in three regions of $\varepsilon_\perp$, corresponding to channelling, quasichannelling and chaotic motion of particles. It is also shown that the diffusion function has a break when the transversal energy equals to the top of the potential barrier of a channel.
