Mine ventilation system building method based on DIMINE software

Abstract

The invention discloses a mine ventilation system building method based on DIMINE software. According to the method, a mine ventilation system three-dimensional model is built through the DIMINE software; the DIMINE file format of the built ventilation system three-dimensional model is converted into a file format compatible with 3DVent software; according to the ventilation network resolution technology requirements, the mine ventilation network resolution work is completed through combining the actual conditions of a mine; according to the ventilation network resolution result, the mine ventilation system design and modification scheme optimization work is completed; according to the ventilation network resolution result, the three-dimensional visualization and air flow animation simulation software realization technology study of the ventilation network resolution result is developed; and the real three-dimensional visualization and air flow animation simulation of the mine ventilation network resolution result is realized. The method has the advantages that the resolution step is simplified; the work efficiency and the accuracy are improved; the electric energy can be saved; the ventilation cost is reduced; the underground microclimate conditions are improved; and a good operation environment is created for underground workers.

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
