In Indonesia, recently and for the future ahead, underground mines and underground infrastructures rapidly developing. To analyze those openings stability, it is of importance to understand the magnitude and the direction of in-situ stress which it can be obtained by hydraulic fracturing test. In present research, a laboratory scale experiment has been conducted in order to understand the influence of triaxial stress condition in hydraulic fracturing test on inclined borehole. Analysis method from breakdown pressure Pb, shut-in pressure Ps, and fracture direction were used to verify magnitude and direction of triaxial stress applied. The result shows that hydraulic fracturing can be applied to predict magnitude and direction of triaxial stress for inclined borehole test by use of ONEV (Origin; North; East; Vertical) axis back-calculation developed by Mizuta (1987).[/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]Back calculation,Breakdown pressure,Inclined boreholes,Shut-in pressure,Tri-axial stress,Triaxial stress condition,Underground construction,Underground infrastructure[/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]Apparent tensile strength,Fracture toughness,Hydraulic fracturing,Triaxial stresses[/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]
