Research on big data analysis and decision system of intelligent mining in transparent working face

In order to better realize the intelligent analysis and decision-making of the mining process of the working face, a transparent working face model was constructed. Through the application of big data fusion technology, model digitization technology, analysis and decision-making technology and machine learning technology, a set of “predictable, predictable” technology was established. Intelligent mining big data analysis and decision-making platform based on judgment and pre-control. The hardware environment and the cluster environment are built, the storage capacity indicators of the virtualized cluster are standardized, and the homepage interface of the big data intelligent analysis and decision-making platform, the geological data interface, the shearer planning interface, the electric hydraulic control planning interface and the coal mining process interface are designed. At the same time, it summarizes the key technologies of intelligent mining big data analysis and decision-making system such as data fusion technology, model digitization technology, analysis and decision technology, machine learning technology and equipment fault self-diagnosis technology. The intelligent mining big data analysis and decision-making platform mainly includes data operation center, data fusion system, algorithm cluster system, decision-making interaction system, verification and evaluation system, etc. The platform realizes the unification of various communication protocol data of different equipment in fully mechanized mining face. Conversion, correlation, classification and storage, and based on mining technology, fully mechanized automatic control technology, inertial navigation technology and radar ranging technology to continuously update and update the transparent geological model, analyze and obtain precise control decision information for fully mechanized mining equipment. Through industrial experiments, geological data was collected and analyzed, a three-level intelligent mining model of transparent working face was established, and the overall design architecture of a transparent working face intelligent mining big data analysis and decision-making system was built, and the use of big data analysis and decision technology was realized,The cutting model is revised in real time, realizing intelligent and precise mining.
