Definition, connotation and progress of digital mining technology under the new situation

3.9 Integrated command and dispatch system

The integrated command and dispatch system of the digital mine is not a simple integration of monitoring, industrial automation, personnel positioning and communication systems, plus some things such as production scheduling logs and reports. It is based on the 3D visualization platform to realize the monitoring, communication and personnel positioning system, as well as the strong integration of production technology management, safety management and mine ERP, mainly to achieve the following functions.

1) Normal production period: you can see the day and cumulative safety information, output information, cost information, reserve information, equipment information, coal quality (ore quality) information, sales information and geological models in 3D mine models, shaft engineering, stope or working face, production equipment, personnel analysis and various monitoring and monitoring systems through a scheduling interface, if necessary, drilling Detailed data of any part, any time, and automatically generate the required statistical charts.

2) Decision analysis period: As long as the business requirements are input, the system can use data mining tools to automatically retrieve the required data, documents, graphics, multimedia and three-dimensional models for the decision-making team to perform overlay, cutting, transformation, calculation and simulation analysis, and can call the relevant method library to assist decision-making when necessary.

3) Disaster relief command period: Once a disaster occurs, in addition to decision analysis and fault diagnosis, the time and space management capability and rapid response function of the system can be fully utilized to realize scheduling optimization and visual emergency command software to minimize losses.

4, digital mine construction standards

In order to establish a real digital mine according to the definition of digital mine, it is necessary to have a complete set of construction specifications, in order to form local, industrial and even national standards, so that it has a unified measurement of digital mine. Its specifications shall include the following.

1) General principles of digital mining technical specifications, including principles and general technologies such as networking, software, data acquisition, communication and control.

2) Classification and coding specification of mine information.

3) Technical specifications for mine data warehouse, including basic architecture, data types, subject layer, metadata format, index format, data cube structure, etc.

4) Monitoring and monitoring communication interface technical specifications: collection - storage (real-time database) - control and other communication protocols, triggering mechanisms and time-bound control.

5) Technical specifications for mine safety monitoring systems, including various monitoring contents, spatial layout, time layout, technical indicators, etc.

6) Mining industrial automation subsystem technical specifications, reliable, automatic, intelligent, closed loop, linkage, easy integration and reduction of personnel as the standard.

7) Technical specifications for mining 4D GIS, including dynamic spatial information management of geology, reserves, surveying, hydrology, facilities, etc.

8) Technical specifications for mine production technology management subsystem, all production systems except geodesy.

9) Technical specification of mine essential safety guarantee system and software system.

10) Technical specifications for mine ERP system.
