摘　　要：根据风力发电机组的自身结构特点,分析了发电机组的易损方式,并结合地表移动与变形对构筑物的影响特征,得出煤矿开采引起的不均匀沉降和倾斜是对风电机组的主要影响因素。以BH煤矿为例,根据发电机组与首采区的位置关系,在工作面初设的基础上,依据概率积分法对工作面进行了优化设计,达到了在提高回采率的基础上,保证地面风机机组的安全运行的目的。According to the structure characteristics of wind turbine generator system,the vulnerable ways of wind turbine are analyzed,and combined with the influence characteristics of surface subsidence on structures,it is concluded that the uneven subsidence and inclination caused by coal mining are the main influencing factors of wind turbine.Taking BH coal mine as an example,according to the position relationship between the generator system and the first mining area,on the basis of the initial design of the working face,the optimization design of the working face is carried out according to the probability integral method.So as to ensure the safe operation of the ground generator system on the basis of improving the recovery rate.
