| 2. | Study of calculation method for discontinuous surface deformation induced by steeply - inclined seam mining 急倾斜煤层开采地表非连续变形计算方法研究 |
| 3. | Two methods , the stereo - analytical method and the time - vector method used for calcu1ation are ones through parallel moving discontinuous surfaces 所采取的赤平投影方法和矢量分析法均是平移结构面进行计算。 |
| 4. | The basic assumption of shi ' s block theory only includes the dip and dip direction of the discontinuous surfaces without their specific locus 摘要石氏块体理论的基本假设中只考虑结构面的产状,而不考虑它在空间中的具体位置。 |
| 5. | So , many key blocks obtained from this theory aren ' t true because the length of discontinuous surface is limited and the specific locus can ' t be determined 因此,由其得出的某些关键块体由于其结构面长度的有限性并不是真正的关键块体而且关键块体具体的空间位置亦不能确定。 |
| 6. | Paralled unconformity and discontinuous surface of sedimentary facies as boundary of sequence , the yanchang formation in the researched area can be divided into four sequence which are belong to model i sequence 以平行不整合面、沉积相突变面作为层序界面,将研究区延长组的型层序分为4个层序。 |
