水力压挤参数的数量化理论正交设计优化法

Orthogonal Design Optional Method of Numerical Theory for Hydraulic Extrusion Parameters

应用正交设计确定水力压挤技术参数的最佳组合,对地质条件稳定的煤层是一种较好的方法。但是,随着水力压挤措施实施及工作面向前推进,地质因素在不断变化,若仍然采用该方法确定的工艺参数压挤,其效果不一定满足水力压挤技术的要求,针对这种情况及影响水力压挤的地质因素既有定性变量,又有定量变量的特征,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不稳定状态下的水力压挤技术参数的最优组合,并结合实例进行了优化研究。

To apply the orthogonal design to confirm the optimal combination parameter of hydraulic extrusion 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 hydraulic extrusion measure and changing of the geological factors. In view of this situation and the characteristic of qualitative variable as welt as quantitative variable of the geological factors affecting hydraulic extrusion. 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 hydraulic extrusion when geological factors is in precarious state and then proceed opti- mization study.
