　　目前，新建的大型矿井和改扩建矿井多数采用多风井分区通风。在多风井生产矿井中，各采区采掘工作面数量随着产量的变化不断增减，相应各采区的风量就必须重新进行调配，致使各风井主扇的工况点也必须改变。然而，各主扇叶角调转多少度数才能使各采区达到预定的风量和阻力，这是当前亟待解决的一个课题。通过实例，运用数学解析法可在短时间内计算得出准确合理的结果，从而找到准确的主扇风叶角度，做到各采区风量的合理分配。从而避免采取人工试调风机叶角或其它方法无法准确解算造成的风量浪费或风量不足的现象，使矿井通风科学合理。

At present,the newly built large mines and the most of reorganization and expansion mines use many airshaft unit ventilation.In many airshaft production mine,the number of working face in each mining area along with the change of yield continuously increase and decrease,correspondingly air volume of each mining area must rede-ploy,the working point of each airshaft main fan also must change.However,the main blades angle how adjustment can make the mining area reach scheduled air volume and resistance,it is a subject urgently to be solved in current. Through the example,using mathematical analytical method in a short period of time to calculate reasonably accurate results,so as to find out the exact main fan blade angle,reasonably allot the air volume of the mining area.Thus a-void using artificial test the fan blade angle or other method,cannot accurately calculate,caused air waste or insuffi-cient air flow phenomenon,make the mine ventilation achieve science and reasonable.
