Groundwater condition on acoal open pit mine slope with a homogeneous groundwater flow media is highly dependent on the type of lithology and the groundwater bearing-rocks. The drain hole on acoal open pit mine slope is very influential on the water discharge and the length of the drain hole. This paper presents a discussion on the effect of drain holeinstallation with an inclination angle of 65° and 90° on the discharge and drain hole length. The results show that the drain hole with an angle of 65° results in greater groundwater discharge than the 90° angle. In addition, the drain hole with inclination angle of 65° is shorter than that of the drain holeinstalled with an inclination angle of 90°, thus reducing the operating costs of the open pit mine slope drainages.[/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]Drain holes,Ground water discharge,Ground water table,Groundwater conditions,Inclination angles,Open-pit mine slopes,Pit mines,Water discharges[/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][/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]https://doi.org/10.1088/1755-1315/212/1/012060[/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]
