Optimization of mine ventilation network feature graph. [PDF]
PLoS ONE, 2020 A ventilation network feature graph can directly and quantitatively represent the features of a ventilation network. To ensure the stability of airflow in a mine and improve ventilation system analysis, we propose a new algorithm to draw ventilation ...

Reliability Calculation of Mine Ventilation Network
Procedia Engineering, 2014 AbstractA good ventilation system should reflect both safety reliable and economical reasonable. Safe and reliable mine ventilation system have high reliability and resilience during normal operation or in the disaster period. There is a close relationship between the reliability of mine ventilation network and the reliability of network branch.

Topology theory of mine ventilation network
Procedia Earth and Planetary Science, 2009 AbstractTopological theory of ventilation network is the basis of mine ventilation simulation system. But there still exists disparity and insufficiency between theory and application. On the basis of in-depth study of ventilation network topological theory, the concept of the real and the simplest fuzzy topological ventilation network are put forward,

Restructuring Simulation of the Ventilation Network [PDF]
Mining Revue, 2021 Abstract Worldwide, the demand for raw materials and materials is constantly increasing, being proportional to the growth of the population. In this sense, the demand and production of solid fuels such as coal has grown steadily. At the level of the European Union, due to the restrictive coal extraction policy, production has steadily
