This paper has made a brief analysis of the museum construction based on the application of the internet, digital information, and varieties of technologies characterized by mature development and adaptability to public demands. According to the mineral-crystallization classification program, the authors put forward a reasonable scheme for mineral classification, designed seven functional structures and corresponding sub-structures, and set up the standard for displaying mineral contents. With such means as 3D technology, multimedia technology and word messages, the mineral digital museum aims at displaying minerals to the audience on the network from the macroscopic shape to the abstract morphology of the crystal as well as its micro-crystal structure and smallest unit structure. It is therefore concluded that the digital museum can play an important role in scientific teaching, promotion of national popular science educationand fostering of creative talents, and can also build a good platform for people's understanding of the mineral world.
