针对目前矿井风流参数测试无法获得巷道的平均风速,存在不能全面监测通风网络的全部信息、监测数据达不到准确测定点、出现监测盲区等问题,结合矿井通风系统的经济型和合理性要求,重点研究风速传感器的最少监测数量和最优安装位置.采用可变模糊集理论分析影响风速传感器选址的指标因素,通过三交河煤矿为例进行现场实验和分析,建立风速传感器可变模糊优选模型.研究结果表明:通过计算相对优属度得出各分支安装风速传感器的合理权重,利用宽度优先搜索算法求出通风网络最小生成树,寻根法确定其基本回路,从而快速准确地确定出风速传感器具体安装的回路分支,得到风速传感器最优选址方案.研究结论为实现通风网路风量无盲区实时动态监测和模拟创造条件.
In view of the fact that the average wind speed of tunnel can not be obtained by the current wind tunnel parameter test, all the information of the ventilation network can not be fully monitored, the monitoring data can not reach the accurate measuring point and the monitoring blind spot appears. Combined with the economical and reasonable requirements of mine ventilation system, The least monitoring quantity and the optimal installation location of the wind speed sensor are researched emphatically.The variable factors affecting the location of the wind speed sensor are analyzed by variable fuzzy set theory.The field experiment and analysis are carried out by taking the Sanjiaohe coal mine as an example to establish the variable fuzzy optimization model of wind speed sensor The results show that the reasonable weight of each branch wind speed sensor is obtained by calculating the relative degree of membership, the minimum spanning tree of ventilation network is obtained by the width first search algorithm, and the root search method is used to determine the basic circuit, so that the wind speed sensor And the optimal branch location of the wind speed sensor is obtained.The results of the research have created the conditions for real-time dynamic monitoring and simulation of the air volume without the blind spot in the ventilation network.
