摘　　要：本文采用正投影方法,对云南禄丰县--平浪煤矿南井田断层构造行迹之应变椭球体进行平面投影处理,应用构造应力场量化分析方法,得出其构造应力场的三个主应力轴产状,分别为:σ_(1):199°∠14.5°,σ_(2): 99°∠33°,σ_(3): 311°∠53°,从而确定南井田其构造应力场特征和构造行迹为一典型“入字型”构造。In this paper,we have the plane projection processing of strain ellipsoid of fault trace with orthographic projection method in S well field of Yipinglang coal deposit in Lufeng,Yunnan,3 principal axes are sprarately:σ_(1):199°∠14.5°,σ_(2): 99°∠33°,σ_(3): 311°∠53°,thus we have demined the upieal“λ”-fom structure of S well field.
