Theoretical And Application Study On The Dynamic Visual Mining And Excavating Management System Of Coal Mine

As a mainstay industry of energy sources in our country, the coal industry has a very important position in national economy. It become a inevitable trend of producing and technology management that Informationization and digitalization of coal mine built in 21 centuries. Nowadays, integrated research on CAD, GIS and visualization is a foreland of development and construction of digitalization technical in coal industry realm.The thesis taking the method of system engineering as instruction, AutoCAD system as work's environment, and making use of the theory of graph and database theories and integration technique, integrated computer application technique such as CAD, GIS and visualization with traditional coal subject, invent the mining and excavating engineering dynamic visual archetype system of coal mine through deep studying related technique that include mining engineering space present of coal mine , engineering designed, the plan drawn up, filling and modifying diagram for survey, safe information management, 3D mold set up and visualization technique. The main research contents includes six parts:①the mining and excavating engineering dynamic visual management system structure of coal mine ;②the present research on the structure of mining and excavating engineering graphic's element storeroom and attribute ;research on the system of inputting based-graphics ;③The GIS data structure of the mining and excavating engineering study;④The management research on designing mining and excavating linking plan ;⑤the safe information management study of mining and excavating engineering;⑥some contents about 3D visualization design and carrying out of the mining and excavating engineering etc.The thesis put forward to developing the project that "the mining and excavating engineering dynamic visualization management system of the coal mine" in virtue of analyzing the application technical such as CAD, GIS and graphic visualization research ,condition, existence problem and development the trend of coal mine etc. It is the first time lead "visualization" and "integration " thought into the production control system of the coal mining and excavating.The paper studied professional graphic element aggregate structure of in the mining and excavating engineering dynamic visualization management of the coal mine. Analyzed composing and classification about the pixel gather of mining and excavating engineering , discussed the mean of information of the pixel space a method, established the structure model of the pixel data of the mining and excavating engineering. The data's model successfully integrates "geometrical attributes" of the pixel with "no- geometrical attribute" together. It is adapt to the attribute mine's graphic with "engineering meaning" processing data. Further more, it studied common and professional pixel of the digging engineering's dynamic management system based on the platform of AutoCAD system, and set up the inputting system of mining and excavating engineering's basically original graphic.According to the data's structure theories of GIS, considering the actual problem, the dynamic management system of the digging engineering was divided the space and attribute information of the mining and excavating engineering into two pattern of data managements, one is common embedded database management bonding with pixel and graphic to save in database of graph; Another is relation database management system that was used in GIS in common and independence from saving graphics .The thesis taking the result of the system engineering research of he coal mine as foundation, combining all kinds of problem and their solution that the writer met in practice of researching and developing computer in coal mine, systemically and thoroughly analyzed the mine mining and excavating engineering design of coal mine , establishing link-up mining and excavating plan about coal mine and the problem about measure graphic of filling and modification. Based on the AutoCAD system environment, the thesis put forward a new method about developing mining and excavating link-up management information system of coal mine and main calculating way process, constructed some sub- system like the design, plan and measure of the digging engineering, diagraph etc. It achieved the dynamic visualization management of mining and excavating engineering come true.In respect that the characteristic of lower degree of informationization , management's weaker ability of safety management and lacking necessary supervision to the safe information, a module of " mining and excavating engineering safe information management system" was designed in the paper. It Carried out a optimization management of safe information integration. The mold raised the safety management level in production and the processing ability of trouble rescue in coal mine. It is come ture that the work of safety and rescue was informationize in mine, and accelerate informationization progress and raise whole level in corporation of the mine industry .The discourse analyzed the 3D model data's characteristic of the mining and excavating engineering of coal mine and the data structure of 3D. Then studied and discussed the way that establish the curved surface's mold of coal seam and the tunnel's 3D mold method based on the graphic platform of the AutoCAD system.
