| 中文摘要: |
| 在对新景煤矿目标区野外节理构造实际观察及测量的基础上,根据节理组之间的互相切割改造关系,对不同期次的节理组进行了划分,同时把同一地点、同一时期、同一应力作用所产生的节理配成套,以便利用它们与主应力方位的关系来确定和恢复古构造应力场。通过对测量点节理倾向走向的统计,做赤平投影图及节理等密度图,表明该区的构造变形至少受到3期应力场的影响,分别为印支期、燕山期和喜山期。 |
| 英文摘要: |
| Based on the analysis of coal mine and field geological structure of Xinjing coal mine, Shanxi Province, systematic observation and measurement of joint structure in the field are carried out. In order to determine and restore the paleotectonic stress field by the relationship between the occurrence of conjugate joints and the orientation of principal stress, the mutual cutting and reconstruction relationship between joint groups and the stages and matching of joint groups are determined. At last, the analysis on the dominant joint in Xinjing coal mine shows that the tectonic deformation in research area is affected by the tectonic stress field in the Indosinian, Yanshanian and Himalayan stages. |
