| 7. | To apply the orthogonal design to confirm the optimal combination parameter of coal seam injection is one good method for the coal seam in a state of stable geological factors 摘要应用正交设计确定煤层注水工艺参数的最佳组合,对地质条件稳定的煤层是一种较好的方法。 |
| 8. | But if so , the effect of injection meets uncertainly the requirement of the project in pace with advancement of the coal seam project and changing of the geological factors 但是,随着煤层注水工程的推进,地质因素不断变化,若仍采用该方法确定的工艺参数注水,其效果不一定满足注水工程的要求。 |
| 9. | In view of this situation and the characteristic of qualitative variable as well as quantitative variable of the geological factors affecting coal seam affusion , put forward the application of numerical theory on the basis of optimization study of orthogonal design to confirm the optimal combination of the technical parameters of coal seam affusion when geological factors is in precarious state and then proceed optimization study with instances 针对这种情况及影响煤层注水的地质因素既有定性变量,又有定量变量的特征,本文在利用正交设计优化研究的基础上,提出利用数量化理论确定地质因素为不稳定状态下的煤层注水工艺参数的最优组合,并结合实例进行了优化研究。 |
