Mining Geography Information System--TT-MGIS2000 is developed by the Mining University of China with the support of the Beijing Oriental TITAN Technology Co., LTD, using the developing control of TITAN GIS and adopting the mode of groupware in the half of bottom layer, and is the first basic landform of national Mining GIS orienting to our Mining fields. This system is integrated by many groupware specially for Mining except for the basic function of general GIS software.

Collectivity Frame of System

In the standard of groupware, TT-MGIS 2000 is divided into basic groupware and Mining groupware.

In the standard of Multi-document Windows, TT-MGIS 2000 is also divided into Figure Window, Data Window and Export Window, as the picture shows. Figure Window is mainly used to show picture layer (including terra object classification and Themes), edit and analysissitus analyze in Themes, etc. Data Window is mainly used to show, edit and query property data; Export Window is mainly used to custom Themes map, groom figure, and print and export, etc.

The Main Functions of System

the function of basic groupware

TT-MGIS 2000 has general functions as follows: graphics file parse, graphics file convert, layer edit, layer show, Themes create, Themes graphic and property data mutually query, Themes graphic analyze in analysissitus, basic tool and export, etc.

the function of Mining groupware

Electronical Mining Map: including mining graphic management in plane classified by layers, levels and species; automatically create drilling histogram, section plane map; layer maintenance including extending laneway, editing the controlling spot of lead, drawing line of working face and arc, extending hollow area in working face and automatic filling up, etc.

Excavate security: including machine and electricity equipment management, ventilation and networks management, mine drainage system management and carving out design, dissoluting simulation, gas analysis, emergency command, emerging water analysis, water and geology, emerging water forecast, transportation management ,etc. special application groupware.

resource environment: including "three down" coal reserves, "three down" coal exploiting trends, concomitant resource management and protecting coal pole design; "three down" coal exploitation design and project contrast; sink in exploitation forecasting and seeking parameter; visual evaluation of exploitation damage, analysis of the state of sink soil and soil again cultivating and programming, etc.

corporation management: including material management, manpower management, production management and laborage benefits.

key technology

Duality data structure detached by graphic category: In TT-MGIS2000, spatial data is graphic data, and non-spatial data is property data (that is subject property), through duality data structure detached by graphic category, spatial data and non-spatial data can be connected through key word.

Three logic levels in graphic data: In the organization of graphic data, it adopts three logic levels including Feature, Feature Classes and Theme.

Attribute library management based on theme: It can organize mining attribute data in the manner of Theme, and deliver determining nature related to the essential of graphics and quantitative characters. When designing the attribute database, it is divided into two parts including ground part and well part, and both include Feature, Surface, Network, TIN and Raster etc. five kinds of Theme attribute database.

Defining engineering file according to workspace (*.TMS): Two workspace file can include several mining graphic window and (or) attribute data window and (or) several mining graphic export window, and can save color and linetype of Feature and Theme graphic element. It can satisfy the requirement of the environment of not continuous work and keeping the memory of work fruit.

Laneway analysissitus and management based on center line: It can freely create crewel laneway according to the requirement of drawing and importing graphics, basing on central line and around instance, and leave central line and crewel each other to different layer for management.

Standard mining information classifying and coding project: Mining graphic information classes adopt linetype classification, and its code is composed of main code and assistant code.
