【摘要】 在对国内外现有可控循环风技术深入了解的基础上，结合矿井实际情况，推导出带漏风的采煤工作面循环风系统的有关计算公式，减少了计算值与实际值的误差，并据此成功地解决了显德旺煤矿2717采煤工作面风量不足问题．图2，参4更多还原

【Abstract】 On the base of knowing about the technology of the controlled recirculating aim the world, some formulas about the working face’s recirculating airflow system associating with leaking alrflow are deduced and obtained, reducing the error between calculating value and real value; and on the base of the above-mentioned formulas, the problem about 2712 working face’s lack of airflow was solved successfully in the Xiandewang coal mine. 2figs., 4refs.更多还原
