升压工作面调风量与升压效果分析

Ventilation Stability Analysis at a Lifting Pressure Coal Face

升压综采工作面又称均压法工作面。随着回采的推进,上下顺槽巷道的风压发生了相应变化,需要对相应通风设施进行适当调节,从而为综采工作面提供稳定的风压。文章对工作面及上下顺槽巷道风流参数进行分析,对于构筑物漏风可能导致工作面邻接巷道形成循环风的边界条件作出了数值模拟。

Lifting pressure coal face is also known as the balance pressure coal face. With the exploiting of mining, the laneway resistance is in the corresponding changing. The corresponding ventilation installations need to be suitably adjusted in order to provide the stable wind pressure for faces. In this paper, the wind paraments in a coal face, upper and lower roadway are analyzed. Toward the air leak of structures may lead to the roadways next faces to form circle wind. Its boundary condition is simulated in numeral.
