Problems solved by technology
The traditional ventilation network calculation method requires the fan branch to be used as a residual tree branch to avoid multiple fan branches in the same circuit. , and it is easy to have many logically related fans, which will cause certain interference to the optimization of multi-level machine station fans
In addition, the iterative process of multi-fan multi-level station ventilation network solution converges slowly and even tends to diverge

The invention discloses a method, a device and a storage medium for calculating a ventilation network of a multi-fan and multi-stage machine station. Wherein, the method includes: creating a spanning tree for the ventilation network of a multi-fan multi-stage station, obtaining a set of residual tree branches of the spanning tree; drawing a closed loop based on each residual tree branch in the set of residual tree branches, And build a set of conflicting residual tree branches; add the residual tree branches that have delineated closed loops to the spanning tree to generate a network diagram; traverse each conflicting residual tree branch in the conflicting residual tree branch set, and update the network diagram , to obtain a minimum independent closed loop; performing an iterative operation on the minimum independent closed loop to obtain a calculation result of the ventilation network.
Description
technical field [0001] The invention relates to the field of mine ventilation, in particular to a multi-fan and multi-stage machine station ventilation network calculation method, device and storage medium. Background technique [0002] With the development of the mining industry, the scale of ore deposit mining is getting bigger and bigger, especially the application of multi-fan multi-stage machine station ventilation method, the scale of mine ventilation system is also enlarged, and the complexity is also increased. [0003] In the related art, many mines have extremely serious downhole circulating air phenomenon due to chaotic fan management. The traditional ventilation network calculation method requires the fan branch to be used as a residual tree branch to avoid multiple fan branches in the same circuit. , and it is easy to have many logically related fans, which will cause some interference to the optimization of multi-level station fans. In addition, the iterative...
