Mine progress measurement to retrieve crees, toe, spot, floor and roof data. From this data, a map of mining progress and coal volume calculations can be obtained, volume calculations are usually carried out after the depiction is carried out, because volume calculations must obtain a 3D shape of coal for which volume will be calculated. The results of coal calculations are usually in the form of tonnage calculations. The results of the calculation of coal in 2021 in July and August there is a comparison of the volume of reserves with those in the stockpile is 908 tons and 2,883 tons, while in 2022 in February and March there is a volume comparison of 3,675 tons and 646 tons.]]>
