The application of big data has begun to play an important role in the construction of smart mines, which will surely promote the rapid development of the integration of industrialization and industrialization in mines, thereby improving the production efficiency of mining enterprises. With the deepening of the construction of smart mines, the accumulation of massive data has become a new ecology, and data has become the means of production and potential productivity factors in the production and management of mining enterprises. In order to make full use of and exert the commercial value and potential of massive data productivity, this talk starts from the analysis of the current situation of smart mine big data, studies the concept, characteristics and application of mine big data, briefly describes big data technology and methods, puts forward the basic plan of big data application platform according to the needs of smart mine, and analyzes the key technology and specific applications that can provide reference for the construction of smart mines.
