The invention provides an automatic control method, a storage medium and a system for a support of a fully mechanized mining face. The automatic control method comprises the following steps of generating control instruction packets each for controlling a support assembly to execute on/off actions; generating graphical display marks each associated with one control instruction packet; acquiring anoperation mode of each graphical display mark, and obtaining an execution action of each support assembly according to the operation mode of each graphical display mark; and collecting the control command packages associated with the execution actions of all support assemblies to obtain an automatic control scheme of the support. According to the scheme, a user can finally generate the automatic control scheme of the support merely by operating the graphical display mark, and various control schemes of the support are realized by selecting the operation combinations of the graphical display marks, so that the operation is simple and easy to implement, and the automatic control of the support is more flexible and efficient.
