    Research on Optimization of Roadway Support Based on Parameterized Numerical Calculation Inversion Analysis

    • 摘要: 提出1种基于参数化数值计算反演分析的巷道支护优化方法,以实测地质力学参数为基础,通过参数化数值计算反演分析获得计算结果与实际矿压显现误差较小的地质力学参数,用以评估不同支护方案的支护效果。在建立支护方案优化流程的基础上,以王坡矿3210孤岛工作面为例,对不同支护方案进行了优化比选。结果表明:引入矿压实测数据作为数值模型准确性评判条件,提高了数值计算法的准确性;为提高计算效率,应选择易于观测的矿压显现参数,作为参数化反演分析的因变量。

       

      Abstract: A roadway support optimization method based on parametric numerical calculation inversion analysis is proposed. Based on the measured values, the geomechanical parameters with less error between the calculated results and the actual mineralization are obtained through the inversion analysis of parameterized numerical calculation, so as to evaluate the support effect of different support schemes. On the basis of the establishment of optimization process of support scheme, taking 3210 isolated island working face of Wangpo Mine as an example, the optimization comparison and selection of different support schemes are carried out. The results show that the accuracy of the numerical calculation method is improved by introducing the measured data of ground pressure as the accuracy evaluation condition of the numerical model. In order to improve the calculation efficiency, the easily observed ground pressure behavior parameters should be selected as the dependent variables of parametric inversion analysis.
