Abstract: In view of ambiguous status of concept, mode and key technologies of intelligentized coal mining, the paper briefly described concept and difference of unmanned technologies, intelligentized technologies and digitization technologies. In combination with the development course and technological means revolution of coal mining technologies, it put forward two kinds of technology mode of intelligentized coal mining ,namely one is the intelligent self-adaptive mining technology mode, the other one is technology mode of working face automation + visual remote intervention half mode intelligent drilling. It also respectively analyzed and researched key technologies of the two kinds of coal mining technology mode. The research results show that the two kinds of technology mode can realize intelligentized mining and meet the demands of practical application， its development trend is crossing and paralleling development in the future, so as to realize intelligent control on coal mining face.
