概要介绍了矿井液压提升机驱动电动机的发电运行工况，分析了所发电电能的主要参数，计算了发电运行状态反馈给电网的平均功率，为进一步研究液压提升机的节能特性提供了一定的参考依据。

In the working condition of put-down loadbearing, the winders electromotor runs in electric power generation mode and feeds back power to eletricity net. This paper introduced the electric power generation working condition of mining hydaulic winder´s electromotor analysed the main parameters of electric power and calculated the feedback average power to eletricity net, which can provide reference to the further study and design of mine winders´ economic running speciality.
