受环境与现场条件的影响,巷道风阻的测定精度很难控制在理想的范围,在矿井风量预测和矿井通风系统优化过程中,巷道风阻又直接影响着风网的解算结果,因此对分支风阻的校验至关重要。改进分支风阻的节点风压法,提出应用多次实测风量、通过2次针对不同目标参数的整体或部分风网参数解算实现风阻校验的一种新算法,并基于matlab平台编制其仿真校验程序。通过matlab仿真校验实际矿井风网的风阻参数,证明了该算法及其程序可快速校验矿井通风网络的分支风阻参数的准确性,解决了以往的校验算法均需闭合回路校验且编程费时、费力的问题。
Affected by the environment and the site conditions, the determination of roadway wind resistance is difficult to control in the ideal range. In the process of mine air volume prediction and mine ventilation system optimization, the roadway air resistance directly affects the solution of wind network. Therefore, The verification is crucial. This paper proposes a new algorithm of wind resistance verification based on the whole or part of the wind network parameter for different target parameters by applying twice measured wind quantity. Based on matlab platform, Test procedures. The mathematic simulation is used to verify the wind resistance parameters of the actual mine wind network, which proves that the algorithm and its program can quickly check the accuracy of the branch wind resistance parameters of the mine ventilation network, and solves the problems that the previous calibration algorithms require closed loop verification and programming Time-consuming, laborious problem.
