Establishment And Research On The Management And Control System Of Mining Equipment In Open-pit Mine Based On The Analysis Of Operational Data Characteristics

Mining is the protection of national economic development,mining technology and means of mining as the basic industries of the national economy grows rapidly with the rapid development of science and technology.In the case of open-pit mine,for example,its production efficiency and benefit depend on the operation efficiency of the equipment and the ability of the entire production system.The continuous improvement of the technical level of open-pit mining equipment speeds up the development speed of mining engineering,but brings challenges to the production organization and management.In recent years,the operation of mining equipment in open-pit mine has developed from a single management to system management and control.Combined with the mining process constraint,how to carry out effective coordination control and auxiliary decision support for the mining and hauling equipment has become an urgent problem to be solved in the field of production management.Therefore,it is of great practical significance to carry out the characteristic analysis of operation data and the research on the management and control system of the mining equipment in the open-pit mine.The process of collaborative management and control of mining equipment in open-pit mine,usually requires a combination of mine production management system and real-time monitoring system of mining equipment,and an establishment of an optimization dispatching and auxiliary decision support system based on studying on the data index and distribution of mining equipment in open-pit mine.In view of this,the paper is carried out the research work on the construction of the management and control system of the mining equipment in the open-pit mine from the point of view of processing algorithm and data feature analysis on the basis of relevant research.The main work of this paper is summarized as follows:1)It studies the architecture of management and control system in open-pit mine.With dispatching and control of shovel and truck implemented in production process as the starting point.In order to improve the operating efficiency of equipment and operating personnel enthusiasm,reduce work intensity and energy consumption and for the purpose of collaborative optimization control,the paper puts forward the step by step implementation strategy of the management and control system of open-pit mining equipment and the construction of cloud computing platform.2)In order to achieve effective control of open-pit mining equipment,the characteristics of the operation data of the mining equipment was studied in the paper.A new method for the matching of playback time sequence of loading and unloading was proposed in the paper which realized the intelligent identification of production equipment operation state and the automatic statistics of production based on the constraint conditions of mining technology,and focuses on the main data sources and processing methods of truck dispatching system in open-pit mines.In the aspect of equipment operation monitoring,this paper put forward the method of expression,simplification and updating based on geographic information attribute data.Finally,the multi-level data structure of open-pit mine was studied,and the effective management of this kind of data was realized.3)The real-time data acquisition and communication architecture,transmission protocol and data conversion method was studied which is based on the truck dispatching system of open-pit mine.The distribution rules and time related statistical indicators of the operation data was proposed in the paper.According to the analysis of temporal index data,the equipment operation data flow and time series prediction method was instructed.Taking into account the practical problems of production management of open-pit mine and the non-stationary time series,it was established in the paper that the Markov chain preconditioning method and the optimal estimation time series model which could provide more data support of real mining technology situation for mine operation control system.4)On the basis of the above research,the data mining framework of mining and hauling system in open-pit mine was studied which combines big data and cloud computing platform in this paper.Taking Fushun West Open-pit Mine Truck Dispatching System as an example,it analyzes the content and format of data collected during the operation of the open-pit mining equipment,and the correlation analysis,cluster analysis and time series analysis are realized by data mining of the big data and cloud computing platform and the Spark-based Computing Engine,which has been used to analyze the correlation among the data of the mining and hauling operation system.5)According to the different levels of information production in open-pit mine,the research and development of Pingshuo opencast mine production management system and Fushun West opencast Mine Truck Dispatching System and Yimin opencast mine decision support system was described based on the mining equipment management system in this paper.Through the practical application,it proves that the management and control system of open-pit mine can do very well of-in the mining equipment management and scheduling control in actual production.With the development of technology,this paper focused on the researches researched and developed developments of the key content of data services,and management and control system of mining equipment and other key contents on the cloud computing application platform in open-pit mine instead of limited in the current level of the development and construction of mine information.In summary,according to the control system of mining equipment,this paper studied the processing method of the operation data of mining equipment and analyzed the characteristics of the data and the distribution rule of the relevant indicators were studied in this paper for thecontrol system of mining equipment.The rule mining and knowledge discovery of the operation data of mine mining equipment operation data was realized through by improving time series model and improved data mining platform.This paper also developed and implemented the corresponding management and control system.A data service based on cloud computing andan open open-pit mine transport equipment management and control platform were constructedby the actual demand of open-pit mine as the background.
