Description

technical field [0001] The invention belongs to the technical field of mine mining process, in particular to a method for constructing a mine ventilation system based on DIMINE software. Background technique [0002] As the shallow mineral resources tend to be exhausted, some non-coal mines in China have entered the stage of mining below a kilometer. The increase in mining depth has led to many mining technical difficulties, among which ventilation problems are particularly prominent. For non-coal mines with a long mining history, deep mining depth, intricate roadways, many middle sections of operations at the same time, scattered working surfaces, long air supply lines, large air leakage, and unsealed goafs and abandoned roadways, ventilation is more difficult. High energy consumption, low fan efficiency, and unsatisfactory ventilation effect. For such mines, if the method of multi-fan and multi-stage machine station ventilation is adopted, the effect will be significantl...

Problems solved by technology

[0005] Complicated preparation of basic data and difficulty in error correction have always been outstanding problems in the calculation of ventilation networks

Traditional wind network calculation software requires manual drawing of ventilation network diagrams, and then numbering network nodes and branches, and sorting and inputting basic data, which is a very tedious task in wind network calculation

Especially for the complex ventilation network of large mines, it is quite difficult to complete the data preparation of hundreds or thousands of numbers one by one by hand

The main problem is that manual operation is time-consuming, laborious, inefficient, and error-prone, which leads to great difficulties in error correction and program adjustment during the calculation process, making it difficult to guarantee the reliability of the calculation results
