Factor of strength deterioration of the coal bearing strata is obvious and geotechnical engineers have been taking account this factor into the slope stability calculation. The potential of slope failure is controlled by the dimension and geometry of the slope, orientation of the discontinuity and its shear strength properties. Thus, a geotechnical researchwhich can link the rock mass characteristics with the shear strength of discontinuity planewas carried out. The research coverage includes determination the most potential slope failure areas embracing of not less than 20 cross sections stretches along 14 km long with the maximum height of slope sectionwas 190 m, geological structure mapping, determination of physical and mechanical properties of intact rock and for determination the shear strength properties were based various sample sizes from 54mm to 1000 mm. In order to develop a slope stability curve (Hoek & Bray, 1981), dimensional functions associated with slope stability assessment were derived. It is however important to note that at present the validation process of this curve has not yet been done. © 2012 Taylor & Francis Group, London.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Bearing strata,Cross section,Dimensional analysis methods,Dimensional functions,Geological structures,Geotechnical,Geotechnical engineers,Indonesia,Intact rocks,Mine site,Open pit coal mine,Physical and mechanical properties,Rock mass characteristics,Sample sizes,Slope failure,Stability analysis,Stability assessment,Stability calculation,Strength deterioration,Strength property,Validation process[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Case studies,Coal mines,Stability analysis[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
