Abstract

The coal mining industry is one of the most important sectors in Indonesia's economy, and it has become a vital part of the national economy. As a result, the mining industry has become more and more digital. The application of the overlay method in this study aims to improve operational efficiency and work safety in the coal mine of PT Putra Perkasa Abadi (PPA) in Indonesia. The overlay method combines WiFi and LTE networks in the mining area, which improves network performance in terms of throughput, latency, packet loss, and signal coverage. The implementation of Strategic Network Planning to Optimize Digital Transformation in the Coal Mining Industry has proven to be effective in improving the quality of networks that support digital transformation in mining areas. The solution has the potential to be applied to other industrial sectors with similar operational challenges, optimizing the use of network technologies to support sustainability and productivity. Overall, this study makes a significant contribution to designing and implementing network systems that can support operational efficiency, improve occupational safety, and offer sustainable and adaptive solutions in the industry, ultimately supporting the digitalization and transformation of the industry.

Abstract

The coal mining industry faces significant safety challenges due to hazardous working environments and manual monitoring processes, particularly involving Tower Lamp units. These activities expose employees to risks, including harsh weather and operational incidents, leading to potential accidents and financial losses. This study proposes an intelligent safety control system employing real-time remote monitoring technology to mitigate these risks. The system enables centralized control of Tower Lamps, reducing manual interactions, improving energy efficiency through automated lighting adjustments, and enhancing workplace safety. The methodology includes designing and implementing a monitoring system with remote control capabilities supported by real-time data analysis. Expected outcomes include reduced work accidents, optimized lighting management, and streamlined operations, showcasing a scalable model for broader industrial applications. This technological innovation demonstrates a practical solution for improving safety and operational efficiency in coal mining environments.

Abstract

Digital transformation is essential to improving productivity and sustainability in mining operations. However, complex topography—such as deep pits, high walls, and uneven terrain—creates significant challenges for wireless communication infrastructure. Standalone Wi-Fi networks suffer from unstable signals, while LTE networks experience blind spots in obstructed areas. Field assessments at a mining site in South Kalimantan, Indonesia, revealed that 21.6% of operational zones recorded LTE RSRP levels below –110 dBm, disrupting key operational connectivity. This study proposes a hybrid LTE–WLAN overlay architecture using dynamic load-balancing and failover mechanisms to ensure reliable, high-speed communication. The approach offers environmental adaptability, network flexibility, and cost-efficiency by combining LTE’s wide-area coverage with WLAN’s localized stability. Simulation results show FTP throughput exceeding 94%, RSRP above –100 dBm in 92.43% of areas, and SINR above 98.40%, with seamless handovers and 100% E-RAB success rates. Bandwidth analysis highlights major fluctuations in standalone Wi-Fi (0–2000 Kbps), whereas the overlay solution maintains stable 2–6 Mbps bandwidth. Connection quality in overlay networks remains above 98%, compared to frequent drops below 50% in standalone Wi-Fi. These findings demonstrate that the LTE-WLAN overlay architecture significantly enhances communication stability and performance across challenging mining environments, addressing the identified connectivity gaps through practical, field-validated implementation. Connection quality and bandwidth utilization are identified as key success parameters, confirming that the proposed solution is practical, scalable, and effective for supporting real-time monitoring, IoT integration, and industrial automation in digital mining.
