- 摘要:
- 为了探究矿井通风网络复杂度与风机控制力的关系，提出分支关联度、最小距离、通风网络复杂度和风机控制力的概念。利用vCad20进行数字实验，对网络复杂度与风机控制力的关系进行定量研究。结果表明：随着网络复杂度的增加，矿井通风系统的有效风量率减小，且认为该值减小到60%时，视为风机控制力的极限，此时网络拓扑结构为风机所能控制的最大网络复杂度。地面集中供风时,同时工作的中段数量存在上限,最大值为7。将结论用于某有色金属矿进行实证研究，找出该矿深部中段通风困难的原因，为矿井进一步整改提供理论依据。
- Abstract:
- In order to explore the relation between network complexity for mine ventilation and control force from main ventilator, the definitions of branch correlation, minimum distance, network complexity and control force from main ventilator were put forward. The software vCad2.0 was applied to quantitatively simulate the relation between network complexity and control force from main ventilator: It showed that with the increase of network complexity, the effective air volume rate of mine ventilation system decreases. When the rate is below 60%, the control force from main ventilator reaches its limitation, and the network topological structure at this time is the largest network complexity that the main ventilator can control. When applying ground centralized air supply, the amount of level working simultaneously has an upper limit, and the maximum amount is 7. The conclusion was used to a certain leadzinc mine, and the causes of difficulty about deep shaft ventilation were found out, which can provide theoretical basis for further rectification.
