| 摘 要： | 本文以樟东坑钨矿床的地质构造为背景、工程地质条件为依据,划分了其岩体结构类型,并应用赤平极射投影方法,求得了该矿床所在地区的构造应力场(σ_1=126°<3°;σ_2=216°<67°;σ_3=36°<23°),进而对矿山目前生产所在地段500m水平以下改分采为合采时岩体的稳定性作了符合客观实际的分析评价。

| Abstract: | The structural types of the rock bodies in Zhang Dong Keng Mine are identified according to the geologic structure and the engineering geologic estimate.And then the tectonic stress field of the mining area is worked out by using the Polar-radiation Equatorial-plane Projection.This provides an objective evaluation of the stability of the rock body by which the decision to change the separate stoping of each vein to sloping several veins combined at altitudes below 500 m can be made |

| Keywords: | geologic structure polar-radiation equatorial-plane projection tectonic stress field the stability of rock bodies |
