摘要
目前煤矿工作面供电距离长，电压降幅度较大，为改善供电质量，保证井下远距离供电安全，提出了对电压降的几种计算方法，结合余吾煤业公司S1202综采工作面现状，验证了该方法的可行性。
Abstract
Currently, the power supply distance is large. In order to improve power supply quality, calculation methods of voltage fall. Combines the feasibility of this method is proved. long at coal mine work face, the amplitude of voltage fall is makes sure the safety of power supply, proposals several current situation of S1202 comprehensive work face, the
