Mine ventilation simulation system of jinchuan 2nd mining area

摘要

Based on a summery to the home and abroad research actuality of mine ventilation simulation system, in accordance with the characters that Jinchuan 2nd mien has no main fan on ground surface, multipolar fan stations are adopted to ventilate underground, three element fators of simulation system are determined systematically, namely ventilation system, mathematical model, computer. Comparing with home and abroad similar achievements, diagonal branch automatic identification and network characteristic graph automatic draw are unique and special functions of the simulation system. Network optimizational regulation path method, based on network minimal regulation power consumption conception, adopted by the system, is different not only from linear programming but also from nonlinear programming. The visualization of ventilation simulation system is realized under Auto CAD environment.
