Evaluation of Grouting Reinforcement Effect of Broken Coal Rock Mass Based on Mathematical Method
In view of how the grouting reinforcement effect of broken coal and rock mass is affected by many factors,the index weight is determined by improved analytic hierarchy process,and the correlation degree between evaluation and standard sequence is determined by grey correlation.The vector grade corresponding to the maximum correlation degree is the evaluation effect grade of grouting reinforcement of broken coal and rockmass.The comprehensive evaluation system of GRA and IAHP with grouting construction effect evalu-ation as the target layer is established.The improved analytic hierarchy process uses"three scales"to determine the judgment matrix to ensure the consistency of the matrix.The effect of coal mine grouting construction project is evaluated.The results show that the grouting reinforcement engineering effect of broken coal and rock mass is"good",the personnel and equipment have a great influence on the grouting reinforcement effect of broken coal and rock mass,which is the focus of the evaluation of grouting reinforcement effect of broken coal and rock mass.The purpose of treatment is basically in good agreement with the evaluation results,which provides a scientific basis for improving the grouting effect.
