Mine ventilation system optimization design development direction

Mine ventilation system design is one of the main contents of mine design. It not only relates to mine construction speed, production time, capital investment, but also has long-term impact on production appearance and technical and economic benefits after mine is put into production. Therefore, mine ventilation The optimization design problem of the system has always been one of the research topics of concern to professionals engaged in mine ventilation work. In recent years, although there have been many research results in this respect, there are still many problems in the optimization design of mine ventilation systems, and some have not been involved. The author believes that the theory and method of optimal design of mine ventilation system should focus on the following three aspects in the future.

1. Comprehensive integration technology from qualitative to quantitative

In recent years, there has been a trend to integrate several existing design methods (case-based, mathematical models, and logical design). Qian Xuesen et al. proposed the concept of an open complex giant system and proposed to study a comprehensive integration technology that deals with such systems from qualitative to quantitative. Dr. Feng Xiating and others proposed a new intelligent approach to the development of mining theory. The rise and deep development of intelligent science (artificial intelligence, neural network, etc.) provides an important basis for the realization of mine ventilation research ideas that integrate the characteristics of the above three solutions. System science provides an important basis for it. The correct mine ventilation research method is to quote some of the advantages of human brain thinking, absorb human intuition, inspiration, combine logical reasoning, associative memory and numerical calculation, and combine uncertainty analysis with deterministic analysis to put people's Knowledge, engineering experience, numerical calculation, on-site monitoring and verification combined with computer technology to establish an intelligent mine ventilation integrated system, and gradually improve the system through self-learning and adaptive mechanisms, and open up a new way. Established in practice to improve intelligent ventilation in development.

2. Development of design support system

The realization of the overall optimization design theory and method of mine ventilation system still needs to use computer as a tool. At the current level of computer hardware and software, it is very difficult to establish an automatic design system. Therefore, the establishment of computer software for mine ventilation system should be supported by design decision. The system (Design Decision Support System, DDSS) is the main one.

3. Optimal layout theory of monitoring points

With the development of the mining industry, the scale of mining is getting larger and larger, the scale of mine ventilation system is also expanding, and the complexity is increasing. Especially the adoption of multi-stage station ventilation system, the system management workload is coming. The bigger. Therefore, the traditional method of managing the system based on artificial experience can not meet the requirements of people's social and economic benefits. The electronic computer and system engineering are used to realize the optimal management and automatic monitoring of the mine ventilation system to make the system safe. Reliable economic operations are imperative. Therefore, in the appropriate position of the system, a certain number of monitoring points are arranged, and the necessary quantity information is provided to reflect the operating state of the system, which is an important link of online optimization management of electronic computers. It can be seen that the theoretical study on the optimal layout of monitoring points for mine ventilation measurement is of great significance.
