Rancangan Dimensi Sump berdasarkan Pertambahan Debit Air yang masuk dalam 3 Bulan Kemajuan Tambang di PT. Khatulistiwa Makmur Persada, Kabupaten Bungo, Provinsi

Abstract

 In the mining industry, high rainfall can hamper mining operations and can reduce production targets that have been planned by the company. Moreover, if open pit mining runs during weather where the intensity of the rain is high, the water from runoff will inundate the ground floor of the pit in the basin area and has the potential to become one of the causes of muddy mining
fronts which will certainly disrupt mining activities. Mine drainage conditions at PT. Khatulistiwa Makmur Persada, especially in pit 1, uses a mine drainage system with the Mine Dewatering method, namely by collecting water that has entered the mining site by making a sump at the mining site. Therefore we need an ideal and appropriate sump dimension design which will be used for the  next 3 months. The shape of the sump recommended by the researcher is a trapezoidal shape, because this shape is commonly used for sumps. Which for this trapezoidal shape has a cross-section of the base and a square-shaped surface with a larger surface area
than the base area and forms an angle of 45
