Intelligent open-pit mine system, framework, content and target

2 Overall Framework

2.1 Overall framework of intelligent open-pit mine

The overall framework of smart mine is conceived according to the basic concept of smart coal mine and designed in combination with business data flow and control flow, as shown in Figure 14. It mainly consists of five parts. They are the intelligent system of surface mine foundation support, the intelligent system of surface mine spatio-temporal evolution, the intelligent system of surface mine equipment and process, the intelligent system of surface mine integrated management, and the intelligent system of surface mine production planning and project management. The overall framework of the intelligent surface mine is shown in Figure 15.

1) Open pit foundation support intelligent system. It is mainly the construction of basic hardware environment, network environment and software environment, which provides basic guarantee for the operation of the entire smart mine.

2) Intelligent system of spatio-temporal evolution of open-pit mine. It is mainly based on the data and visual model management of geology, survey, mining, etc., to provide basic scenario simulation and other applications for production planning and efficient management and control.

3) Open pit equipment and process intelligence system. It is mainly to carry out intelligent transformation and upgrading of the existing production link engineering equipment such as penetration, mining, transportation, crushing and abandonment, more accurate and efficient data collection, more effective service in production, and further improve engineering operations through the connection of various production links.

4) Open pit production planning and engineering intelligence system. It is mainly based on the spatio-temporal evolution intelligent system of open pit mine and the real-time data collection of production task instructions and monitoring terminals to further revise the production plan, so as to verify the level of project quality and improve the accurate matching of production plan and project.

5) Intelligent system for integrated open-pit management. It is mainly a comprehensive management system for safety, production, operation and management, which analyzes the production data, safety-based monitoring data and operation-based management data generated in each production link through the big data analysis platform, and carries out comprehensive management and application from the aspects of safety, efficiency, green and harmony.

2.2 Overall process design

1) When the planning department receives the production planning task, the production design department makes the production plan based on the spatio-temporal model evolution model system, and forms the production plan result data through production simulation.

2) The production plan result data will be sent to each production engineering unit according to the production plan through the open-pit integrated management system, and the engineering construction unit will carry out the engineering work according to the planned tasks and the working environment parameters obtained on site, and the data will be further collected by the sensor equipment such as working condition parameters, environmental monitoring and safety monitoring.

3) In the process of engineering equipment operation, the data acquired in real time is uploaded to the big data analysis platform, and the expert knowledge base and analysis and diagnosis model initially established are used to analyze and diagnose the current production process [18], and the diagnosis results are given, which are then transmitted to the terminal of production equipment in real time to further guide engineering operations.

4) After the completion of the production operation, the project quality is evaluated and confirmed, the quality detection data is uploaded to the data center, and the production design and project construction are compared and analyzed through the open-pit integrated management system to further optimize the production design and guide the project construction.

The above business data flow and control flow are mainly designed around the production link, based on the trend of data flow and combined with the business control flow, closed-loop management is formed through five main systems, thus forming the overall framework of the smart mine.

3 Construction Content

According to the current intelligent technology development and planning concept, the intelligent open pit mine can be planned and constructed in two phases, the intelligent system of open pit foundation support, the intelligent system of open pit spatio-temporal evolution, the intelligent system of open pit equipment and process, the intelligent system of open pit production planning and project management, and the intelligent system of open pit comprehensive management

3.1 Basic support intelligent system planning objectives:

(1) Phase I objectives
