[Abstract]:In view of the fact that the average wind speed of roadway can not be obtained by the measurement of mine air flow parameters at present, there are some problems such as not being able to fully monitor all the information of ventilation network, the monitoring data being unable to reach the accurate measuring point, and the blind area of monitoring appearing. Combined with the economical and reasonable requirements of mine ventilation system, the minimum monitoring quantity and optimal installation position of wind speed sensors are studied emphatically. The variable fuzzy set theory is used to analyze the index factors that affect the location of wind speed sensor. The model of variable fuzzy optimal selection of wind speed sensor is established by field experiment and analysis of Sanjiaohe coal mine as an example. The results show that the reasonable weight of wind speed sensors is obtained by calculating the relative optimum degree, the minimum spanning tree of ventilation network is obtained by width first search algorithm, and the basic loop is determined by root seeking method. Thus, the loop branch of wind speed sensor is determined quickly and accurately, and the optimal location scheme of wind speed sensor is obtained. The research results provide conditions for the realization of real-time dynamic monitoring and simulation of ventilation network air volume without blind area.
