摘　　要：老厂矿区位于老厂 圭山盆地北半部,应力场属于曲靖台褶束和师宗 罗平褶断束过渡带的合力场。除东西向挤压作用外,还存在三个右旋应力场同时作用的影响,由此处于拉张开放条件,对煤层气储存运移有利。本文将老厂矿区划分成五个区块,并优选有利于煤层气勘探部位。Laochang mining area is located in the north half part of Laochang-Guishan basin. The stress field belongs to the composite force field of the transitional zone between Qujing platformal fold bundle and Shizong-Luoping fold fault bundle. Besides the EW-wards compression, there is the influence of contemporaneous action of 3 right-lateral stress fields. Therefore, it is located in the tension and open environment, which is advantageous to the reservation and migration of seam gas. In this paper, we divide Laochang Mining area into 5 blocks and select the advantageous part to seam gas exploration.
