Discussion on Key Technologies and Engineering Practice of Intelligent Tunneling in Coal Mine

Intelligent coal mine is the major demand and important development direction of coal industry technology innovation in the new era. The purpose of intelligent driving construction of coal mine is to realize the intelligent, efficient, safe and healthy operation of driving operation, so as to achieve the ultimate unmanned/few person tunneling. However, due to the complexity of coal mine driving process, the development of intelligent driving is far behind the intelligent mining face. This paper analyzes the research progress in the related fields of coal mine intelligent tunneling, and discusses the main technical problems to be solved in the future:（1）the intelligent perception and analysis technology of advanced geological environment information based on unified data fusion is proposed to improve the visualization level of mine information and provide information basis for environmental recognition and intelligent decision-making;（2）the research and development can be highly integrated The new intelligent tunneling equipment with the functions of precise attitude positioning, autonomous navigation, adaptive cutting, remote operation and monitoring and monitoring can further reduce the working staff of the working face;（3）the automatic drilling and bolting equipment with high adaptability is the key to improve the tunneling efficiency, and the support operation can be completed efficiently by means of automation, providing necessary safe working space for equipment and personnel;（4）The network control multi-level and multi block information decision-making center is established to interconnect self-decision-making, mutual communication and command transmission among equipment, so as to realize the coordinated linkage of complete sets of tunneling equipment. Taking Ji_15-17-12110 intelligent heading face in Shoushan No.1 mine of Pingdingshan Shenma Group as a typical case, this paper further expounds several key technical problems and realization approaches of intelligent tunneling system.
