Analyzing and processing mine wind speed monitoring data is the key to realizing intelligent ventilation real-time calculation of network. According characteristics artificial regulation a system, local regression fuzzy C clustering algorithm proposed in this paper, which combines outlier with global air volume state analysis. Firstly, uses robust weighted principle analyze preprocess locally, ...

Subway is consisted of tunnels, platforms and ventilation shafts. The air flow between these structures forms a ventilation network. There is a need for fire modeling tools capable of both rapid and precise simulation for fire and smoke propagation in such ventilation network. Computational Fluid Dynamics (CFD) is widely used in subway fire performance design. However, the boundary conditions u...

A reliability analysis of a dumper machine is performed using the neural network model. A metaheuristic algorithm is applied for proper parameter selection for the neural network. A time series approach is applied in the reliability analysis to forecast the dumper’s future failure time. The time series analysis is performed using the neural network model, where the numbers of input variables fo...

Over the years, ventilation systems used in coal mines have become more and complex. Due to a lack of scientific effective management, energy consumed by has rapidly increased, resulting considerable wasted energy. To solve this problem, authors established nonlinear optimization model aimed at minimizing total consumption mine network. Furthermore, propose an improved equilibrium optimizer alg...
