Concept, realization path and key technologies of intelligent mining based on transparent longwall face

Taking transparent coal seam, transparent fully-mechanized mining equipment and transparent decision-making and control as core, concept of intelligent mining based on transparent longwall face was put forward, namely based on enhanced geological perception of coal seam in fully-mechanized mining face, comprehensive perception, information integration and analysis, intelligent production decision-making and adaptive control of fully-mechanized mining equipment are realized in mining process. Realization path of intelligent mining based on transparent longwall face was pointed out from four levels of perception, analysis, decision-making and execution, that is, advanced detection of coal seam, equipment-environment model correlation, pre-mining planning and decision-making and intelligent control wihile mining. Three key technologies of intelligent mining based on transparent longwall face were described, which were geological exploration technology, fully-mechanized mining equipment positioning technology and 3D laser scanning technology. Intelligent mining based on transparent longwall face aims to achieve intelligent decision-making and autonomous implementation of fully-mechanized mining equipment, which can lay a solid foundation for realization of unmanned mining.
