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

3.6 Intrinsic security guarantee system and software system

One of the important differences between mining enterprises and other production enterprises is that there are many dangerous sources that are difficult to detect and identify in mining production (especially underground mining), such as rock burst, roof collapse and collapse, water inrush and flooding, fire, gas outburst and explosion, coal dust outburst and explosion, and mechanical and electrical transportation accidents, large casualty accidents occur from time to time, seriously threatening personal safety .

There is an essential difference between the intrinsic safety guarantee system and the intrinsic safety inspection system. The guarantee system realizes the transparent management of all objects on the ground and underground with the help of the advanced four-dimensional geographic information system, so that the entire mine from design, production to management can well take into account the advanced nature of the process, the reliability of the equipment and the safety of the environment, and greatly improve the disaster resistance and production efficiency Under the management and control system, with strict and standardized management, perfect and practical methods, advanced science and technology, we can truly realize the permanent safety goal of personnel without mistakes, equipment without faults, system without defects, and management without loopholes. Its specific contents are as follows.

1) Establish an inspection, supervision and evaluation system for intrinsic safety.

2) Establish the mechanism research and accident simulation system of major disasters.

3) Establish hazard source identification and disaster early warning system.

4) Establish hidden danger investigation and accident prediction and forecast system.

5) Establish a decision support system for key disaster prevention technologies.

6) Establish an information security system for coal mine essential safety.

7) Establish a long-term management system for coal mine intrinsic safety.

3.7 Production technology management system

Production technology management system is the core content of digital mine, which mainly includes geo-survey GIS, mining cooperative design system, intelligent mine protection system, transmission and distribution GIS, industrial pipe network GIS and so on.

However, it should be noted that this production technology management is not to move the manual method to the computer, but to achieve scientific standardized management and highly intelligent technical support. For example, geodesic geographic information system is not a geological survey map, but through refined mine survey and geological exploration, to achieve the accurate delineation and visual calculation of mineral deposits, geological bodies, hazards and shaft and roadway engineering, can automatically complete a variety of measurement correction, error prediction, measurement adjustment, surface subsidence prediction and other calculations, and realize all calculations WYSIWYG, and can be automatically generated Various mine maps of arbitrary scale provide geological guarantee for mine production, safety and management; The mining cooperative design system based on 3D geographic information system can complete various designs including roadway layout, rock displacement prediction, protection pillar (coal pillar) calculation, support selection, mining, excavation, machinery, transportation, access, safety, etc., and generate related documents. The main purpose of intelligent mine ventilation system is to ensure real-time on-demand wind supply in normal production period and disaster period. The main function of transmission and distribution GIS is to realize the most optimal type of equipment, fault current calculation, voltage and energy loss calculation, capacitance current calculation, dynamic and thermal stability calculation and protection device setting calculation, and to realize remote communication, telemetry, remote and remote control with power supply SCADA system. And so on for other systems. These are imitative methods that cannot be accomplished.

3.8 Mine ERP system

Mine ERP system is the realization of fine management of information security system, mainly including human resource management system, equipment management system, 50 Lu Xinming, etc. : digital mine definition, connotation and progress 2010 first phase material management system, transportation and marketing management system, production planning management system, property management system, budget and cost management system, financial management system, office Dynamic system, etc. Its characteristics are that it must be seamlessly integrated with other systems, such as human resource management, production planning management, material requirements, budget and cost management must be based on design results and production technology, equipment management, material management, marketing management must be aided by geographic information system to achieve on-site management and optimal distribution, other subsystems are similar, or basic data Originating from other systems, or serving other systems, they can all be seamlessly integrated through data warehouses, or they become silos of information.
