摘要：为了更为准确地描述压入式掘进通风流场形态，针对压入式掘进通风流场的传统“接触式” 测量方式的局限性，利用粒子成像测速系统(PIV)对掘进工作面流场进行“非接触式"二维实验测试。按照与实际掘进港道断面尺寸1：15的比例建立了压入式掘进通风巷道实验模型，并根据并下实际情况，将风简悬挂于巷道模型侧壁中央，对经过风简轴心的横纵断面进行实验测试。实验结果表明，PIV 测速系统能够更准确地对复杂流场进行测试，能够得到风流流场的瞬时和时均流动状态，为压入式掘进通风流场特性研究及掘进工作面的排污降尘提供了可靠的实验依据。

Abstract : For more aceurate description of the flow field fom of the forced ventilation system for roadway heading and in view of the limitation of the traditional " contact" measurement method for the flow field of the forced ventilation, the " non-contact" 2D experimental measurement of flow field in the heading face was conducted by using the particle image velocimetry( PIV). An experimental forced ventilation model for roadway heading was established acoording to the proportion of 1 : 15 to the actual crosssection of the roadway, and based on the underground conditions, the air duct was hung in the center of the model tunnel sidewall, and experimental tests were made on the the flow field passing through the horizontal and vertical sections of the air duct axis. The experimental results showed that the PIV system could be used to accurately measure the
complex flow field, and the instantaneous and tim
raged flow state of the flow field oould be got, this thus provided the
reliable experimental basis for the research of the flow field characteristics of the forced heading ventilation and dust prevention in the heading face.

复杂，而要想提高局部通风效率，掌握工作面瓦斯及粉尘的运移规律，就必须对掘进工作面流场特性进行分析，因此掘进工作面通风流场的精准测量就尤为重要。以往传统的通风流场测量手段（皮托管测速、转子流量计测速、热线风速仪)中[2，在实验室条件下测量时仪器设备的探测感知部分必须处在流场中才能完成实验测试，此时仪器设备对风流自身会产生一定影响，使测量结果产生一定的偏差，影响测试精度；在井下实际测量时除了仪器设备外，测试人
