摘　　要：在实际的矿井通风过程中,由于巷道阻力的变化或通风设施的改变,矿井工作面的风速会出现一定的波动,这一定程度上影响了采煤工作人员的工作效率和人身安全。将统计学中的假设检验运用到矿井风速检测的工作中,通过对工作面风速数据的整理和计算,判断工作面风速的稳定性,为煤矿安全管理提供量的指标。运用假设检验方法,不仅可以检验管理人员的判断是否准确,还能度量做出错误结论的风险,有利于提高矿井安全性和可靠性。In the actual process of mine ventilation,due to changes of roadway resistance and ventilation facilities,the speed of wind in mine face appears differences,which affects staff efficiency and personal safety to a certain extent. Hypothesis test of statistics is applied to the speed of wind, By collation and calculation of face wind speed data, determining wind speed stability, providing indicator of coal mine safety management.Forthputting hypothesis test methods, not only can test management personnel to determine, but also to measure the risk of making the wrong conclusions, conducive to improve mine safety and reliability.
