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 multi-fan multi-station ventilation network resolving method and device and a storage medium. The method comprises the steps that: a spanning tree is created for a multi-fanmulti-station ventilation network, and a residual tree branch set of the spanning tree is obtained; based on each residual tree branch in the residual tree branch set, closed loops are circled, and aconflict residual tree branch set is constructed; the remaining tree branches with the circled closed loops are added to the spanning tree, so that a network graph is generated; each conflict residualtree branch in the conflict residual tree branch set is traversed, and the network graph is updated, so that a minimum independent closed loop can be obtained; and iterative operation is performed onthe minimum independent closed loop to obtain a resolving 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...
