System engineering and key technologies research and practice of smart mine
In order to overcome the problems existed in the construction process of complex giant system of smart mine,the overall technical framework of smart mine construction was proposed,and a detailed description was made from the aspects of smart mine system model construction,underground space reconstruction and model dynamic update,machine vision measurement technology,radio frequency explosion-proof test method of gas environment,mine safety closed-loop control system,smart mine standard system,etc.The smart mine was divided into information sensing support layer,edge computing layer,cloud data center,multi-type network,intelligent mine production management and control platform,in-telligent mine production system and intelligent mine operation and maintenance management system.The smart mine technology architecture based on the deep integration of multiple systems was built.Based on the knowledge map and in-formation extraction of smart mine,a smart mine system model driven by data innovation,based on communication net-work and centered on data computing power was constructed.A 3D visual space model based on machine vision percep-tion information and supplemented by other perception information was constructed,and a 3D vision and spatial recon-struction framework of mine underground scene was proposed to realize the reconstruction and dynamic update of the 3D space of underground mine.Based on machine vision technology,the identification algorithm of downhole equipment pos-ition and coal-rock interface was developed to realize the simultaneous aerial measurement of fully mechanized mining equipment group and coal-rock interface.The limitations and shortcomings of the current explosion-proof standards on the power of 5G base stations in the underground gas environment were discussed,and a special test device for radio-fre-quency electromagnetic energy explosion-proof was designed and developed,which provides a method for reference to improve the power threshold of underground 5G base stations.The technical framework of mine disaster closed-loop man-agement and control system,which integrates comprehensive perception of disaster information,independent decision-making of prevention and control plan,and coordinated control of prevention and control equipment,was proposed to real-ize advanced prediction and early warning and coordinated prevention and control of underground disasters.The frame-work of intelligent coal mine standard system was constructed,the typical cases of intelligent construction of coal mine and metal mine in China were analyzed,and the development trend and suggestions of intelligent mine construction were put forward.
