摘要
针对安家岭一号井工矿通风系统存在的问题,介绍了矿井主要通风机的测试过程及相关方法,并且进行相关参数的计算和绘制风机性能曲线图,利用最小二乘法拟合了二阶主扇性能曲线,得出井工矿主要通风机的运行变化规律,为保证其安全高效行和风量调节提供可靠的理论依据。
On the existing problems in the ventilation system of the No. 1 underground mine in Anjialing, the author introduced the testing process and associated methods of the main fans. The author also calculated the relevant parameters and drew the fan performance curve, used the least square method to fit the second main fan performance curve and finally found the regulation of the running variation of the main fan in the underground mine, which provides the reliable theoretical basis for its safe and efficient running and the air volume.
