摘要
在模型巷道模拟试验的基础上，对无底杜崩落采矿法采场进路中利用附壁射流通风进行了工业试验研究。重点探讨了两台射流风机串联作业时的风流结构，包括边界特征、轴心速度、射流截面上速度、流量、射程及排尘等变化规律。提出了采场进路利用无风简射流风机遇风的技术方案和关键的技术参数。试验研究结果表明，利用附壁射流实现来场进路通风是可行的。
On the basis of the simulation trial on the adit models, the industrial trial of along-wall jet-flowventillation in the access drifts to stopes for caving mining without bottom pillars was been done- Thispaper discusses the air fIow structure during the running of two jet ventilators in series including thefeatures of boundary and the regularities of changes of the air velocity in centre, the air velocity incross section of jet flow, air flow rate, jet path, dust removing and so on F suggestes the technical ver-sions and key technical parameters of jet-flow ventilation. The results from the trial show that it is fea-sible to use the jet ventilation in access drifts to the stopes.
