Orthogonal Design Optimal Method of the Numerical Theory for the Coal Seam Injection Parameters
煤层注水参数的数量化理论正交设计优化法

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. 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. 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. Experimentations have indicated that the method saved affusion work and approached actual project's requirement.
