Determine the Weights of Geotechnical Parameters of Over Burden Dump Slope by Implementation of Analytic Hierarchy Process
The assessment of the overburden dump slope involves consideration of both geometric and geotechnical parameters. Geometric parameters, encompassing bench width, bench height, and the angle of inclination, along with geotechnical parameters comprising moisture content, permeability, cohesion, and internal angle of friction, constitute significant determinants. In addressing this complexity, Multi-Criteria Decision Making (MCDM) techniques are imperative for discerning the most and least favorable alternatives in computing the factor of safety. The initial phase of MCDM application involves the establishment of criterion weights through the Analytic Hierarchy Process (AHP). In this proposed study, the AHP method is specifically employed to compute the weights of geotechnical parameters for dump slope stability analysis. Four attributes or criteria, namely cohesion, internal angle of friction, moisture content, and permeability, are meticulously selected for the determination of their respective weights. To gauge the relative importance of each criterion based on geotechnical parameters, a comprehensive questionnaire survey is conducted among academicians, geotechnical consultants, and mining professionals. Respondents are tasked with ranking the importance of each criterion using a relative importance scale. The collected responses are utilized to generate a pairwise comparison matrix for the criteria. Subsequently, a normalized pairwise matrix is computed to derive the weights of the criteria. A consistency test is implemented to validate the data acquired from the questionnaire survey, with a consistency ratio below 0.1 signifying the data’s validity. The Analytic Hierarchy Process serves as the inaugural phase in the execution of Multi-Criteria Decision Making techniques. The criterion weights obtained from the AHP method are instrumental in the selection of optimal or suboptimal alternatives for dump slope stability through MCDM. By employing the Analytic Hierarchy Process, the weights of the geotechnical parameters for the overburden dump slope are ascertained. These weights assume a pivotal role in subsequent analyses, furnishing a quantitative foundation for assessing the relative influence of each parameter on slope stability.
