Basic Information Platform for Digital Mine Based on 3DGIS
Digital Mine: it means to establish an information model in range of coal mine
based on 3D coordinate and to describe all information of each
point in mine. Organizing and storing mine information according to
3D coordinate, with effective, convenient and visual search and
display methods, it makes related personnel be able to master and
utilize various mine information rapidly, exactly and completely.
Which is to say, digital mine is integration of information frame
based on 3D coordinate and its mutual relations and received
information embedding in the frame. Thus there are two levels to
explain digital mine: the first level is to digitize fixed
information (relatively fixed information directly related to space
position such as landform, geology underground, excavating plans,
finished project underground and so on) and establish a digital
mine based on 3D coordinate, describing the mine and mine body
completely and detailedly; the second level is to embed all related
information (relatively dynamic information indirectly related to
space position such as managements of storage, electromechanical,
human resource, production and technology) based on the first level
to form a multidimensional digital mine.
Basic Information Platform for Digital Mine Based on 3DGIS: With its core business for production systems for coal mine
including geology survey system, shaft and laneway system,
excavating surface, underground power distribution, transportation
system, ventilation system, water supply and drainage system, fire
preventing and extinguishing system, evacuating route system,
hoisting system, coal preparation system, loading system, etc,
based on principle of data integration, fusion and share, Basic
Information Platform for Digital Mine Based on 3DGIS classifies
information of coal mine into fixed information and dynamic
information according to concept and development target of digital
mine and view of mine manager how to use the information. The fixed
information includes geological information such as laneway, coal
bed based on geology survey, and the dynamic information includes
information of environment underground, devices and personnel
during production process. Based on these, starting from realizing
digitization of basic information of coal mine, and taking
consideration of different information generating and collecting
modes of each subsystem, the platform smoothly integrates various
basic information from different data sources together under a
space reference coordinate with 3DGIS technology, displays the
information vividly with 2D vectorgraph or 3D model through
software, provides data interface for analyzing and decision-making
of each subsystem and assists safe production process
scientifically, so as to prepare solid ground for higher
informationization of production and business management for
enterprises.
Basic Information Platform for Digital Mine and application
systems: Basic Information Platform for Digital Mine provides mine-used
objects and its basic data with a system for storing, organizing
and managing, accessing, integrating, representing and release, and
its bottom provides API of DLL, COM, Web Services. Application
systems for mine need to be developed upon the platform. Thus,
Basic Information Platform for Digital Mine is the basic for other
application systems, and upon the platform the application systems
for mine can be developed rapidly and professionally, upon mutual
dependence.
Design Principles of Basic Information Platform for Digital Mine:
Principle of Standard: formulating standard data exchanging format,
standardizing basic data of various systems for mine;
Principle of Basic: emphasizing basic, originality, atomicity of
system data for digital mine;
Principle of Openness: open interfaces for secondary development;
Principle of Service: providing all the system data in service mode
for decentralized integration;
Principles of advancement, reliability, economization,
applicability, and expandability.
