Research On Dynamic Management System Of Fully Mechanized Mining Face Production Process Based On True Three-dimensional Environment

The 13 th Five-Year Plan of Coal Industry defines the direction of future coal development.Digital mine technology has made significant breakthroughs.Coal enterprises need to change urgently.The information,digitization and internalization of coal mines are the general trend.In recent years,great breakthroughs have been made in automation and internalization of mechanical equipment in fully mechanized mining face.On this basis,many experts put forward the forming factors of digitized,intelligent and unmanned fully mechanized mining face.The traditional management mode of fully mechanized mining face can not fully meet the production needs.In this paper,the advantages and disadvantages of a large number of three-dimensional modeling and the structure of traditional production management system of fully mechanized mining face are compared and studied.The theory and technology of three-dimensional modeling,GIS theory,computer algorithm foundation,geostatistics,computer simulation technology,three-dimensional visualization technology,database management technology and other fields are comprehensively applied.By analyzing the characteristics ofthe production process of fully mechanized mining face,the author develops a fully mechanized mining face.Dynamic management system of production process.This system is based on AutoCAD 2014 platform,and uses Visual LISP language and Microsoft Access 2007 database,which are configured in the integrated development environment(IDE)of the CAD system.This paper has carried on the following level research and discussion:(1)Based on the real situation of fully mechanized mining face,the author constructs the true three-dimensional environment of fully mechanized mining face,designs the dynamic management information system of production process of fully mechanized mining face,and establishes a platform for the digitization,visualization and internalization of production management of fully mechanized mining face.In order to meet the needs of the production process of fully mechanized mining face,the corresponding modules are designed and developed,and the overall design of the dynamic management information system for the production process of fully mechanized mining face is completed.(2)By analyzing the characteristics and methods of a large number of three-dimensional modeling,the author puts forward a production process model of fully mechanized mining face,which is based on the AutoCAD platform arc spline curve production process modeling method,to model the production process of fully mechanized mining face.At the same time,the production process model is revised by the newly revealed data from the actual productionmeasurement,which can accurately guide the dynamic process of the production process of fully mechanized mining face.(3)According to the true three-dimensional environment and the production process model of fully mechanized mining face,the author constructs the computer algorithm,which provides the theoretical basis for the production process of fully mechanized mining face.(4)Applying Access 2007 database software to manage the data of fully mechanized mining face,dividing the fully mechanized mining face,realizing real-time monitoring of production and recovery rate of fully mechanized mining face through one-knife coal,effectively carrying out production control.(5)Based on the demonstration model of production process of fully mechanized mining face,the dynamic demonstration of production process of fully mechanized mining face is made by using computer simulation technology,and the visualization effect of production process of fully mechanized mining face is improved.Mining technicians can use this model to guide the production process of fully mechanized mining face in real time and improve the utilization rate of machinery.The visualization effect of fully mechanized mining face is improved,and the model and system formed promote the development of digitization,visualization and internalization of fully mechanized mining face.
