Abstract

The Mining industry in Indonesia plays a vital role as a source of state income and an integral part of the industrial progress of the nation. The majority of the mining industry in Indonesia employs open-pit mining. One of the weather factors that can be an obstacle in open-pit mining is rainfall. Therefore, this research focused on modelling data from rainfall, working hours and production outcomes. It applied the Artificial Neural Network algorithm with an input layer consisting of two neurons, a hidden layer with two neurons, and an output layer. The data on Rainfall working hours, and production results were trained to produce a model that, later on, will be used to predict the value of production results. For model testing, this study uses two parameters, namely learning rate and epoch. From 90 times of testing, the best model was obtained with a learning rate value of 0.3 and an epoch of 1000 which resulted in an RMSE error of 0.004838259401280330

Abstract

PT  X, located in Pasuruan, East Java, has been exploring for sirtu (sand and gravel) in a Mining Business License (IUP) area of 12.12 hectares. This study aims to estimate the quality and quantity of sirtu using two methods, namely Cross Section and Contour. The estimation results show that the volume of top soil obtained through the Cross Section method is 428,253 m³, while the Contour method produces a slightly lower volume of 417,964 m³. For the sludge volume, the Cross Section method estimated a volume of 7,404,289 m³, while the Contour method gave a higher estimate of 7,579,433 m³. The difference in estimation results between the two methods is due to the distance between the incisions used in the measurements as well as differences in the methodological approach. The total difference in volume obtained from the two methods amounted to 175,144 m³. This study provides important insights into the potential sludge resources in the ASA IUP area and shows how different methods can affect the estimation results. With this information, it is hoped that the company can make better decisions in the management and utilization of existing sludge resources. This research also emphasizes the importance of choosing the right method in natural resource exploration to obtain accurate and reliable estimates.

Abstract

This research undertakes a thorough evaluation of the drainage systems in the disposal areas at PT. Bukit Asam during the October 2023 sequence, with the objective of understanding the factors that influence the capacity and efficiency of disposal mounds, the density of materials used, the geometric structure of disposal sites, and the design dimensions of open drainage channels. Utilizing the trapezium volume formula, the study meticulously calculated the planned disposal volumes at various elevations—2,289,155 Bank Cubic Meters (BCM) at 36 meters, 1,004,112 BCM at 42 meters, and 669,892 BCM at 48 meters—comparing these against an actual obtained volume of 1,799,111.4 BCM. The substantial variance between the planned and actual volumes highlights the critical challenges in achieving predictive accuracy in disposal management. Further assessments were conducted using the Dynamic Cone Penetrometer (DCP) with a 60-degree cone to determine the density and sub-grade California Bearing Ratio (CBR) of the barrier materials, which were found to be suitable for road construction, falling under sub-grade C classification. Moreover, the Gumbel method was applied to devise the dimensions of a trapezoidal open channel, designed to facilitate a drainage capacity of 100,432.996 cubic meters per hour over a length of 3000 meters. The channel dimensions included a bottom width of 1.1 meters, a top width of 2.3 meters, a depth of 2.4 meters, and a 45-degree slope, with a Manning’s coefficient (n) of 0.03. This detailed inquiry not only provides vital insights into the operational adjustments required for effective drainage but also promotes the adoption of sustainable and safe disposal management practices in the mining industry. The findings from this study serve as a pivotal reference for future improvements in the design and management of mine waste disposal systems
