Freeport Underground Mine Accident Victims: Identities Confirmed The Freeport underground mine accident victims have been identified after a tragic incident at the Grasberg Block Cave (GBC) in Tembagapura, Mimika, Papua. A wet material slide trapped several workers in the underground mine. On Saturday, September 20, 2025, at 08:45 WIT, the rescue team of PT Freeport

The Use of Undisturbed Samples (UDS) in Numerical Modeling (PLAXIS, Geo5, MIDAS GTS) In geotechnical engineering, accurate data is the foundation of safe and reliable design. One of the most valuable sources of this data is the Undisturbed Sample (UDS)—a soil sample taken with minimal disturbance, preserving its natural structure, water content, and mechanical properties.

Understanding Job Safety Analysis (JSA) to Improve Workplace Safety Workplace safety is not just a legal requirement—it is the foundation of productivity, efficiency, and employee well-being. One of the most effective tools used worldwide to manage risks and prevent accidents is Job Safety Analysis (JSA). This method helps organizations systematically identify hazards, evaluate risks, and

Cyclic Simple Shear Test on Soils in Indonesian Mining Areas The Cyclic Simple Shear Test is one of the most reliable laboratory methods used to evaluate the cyclic behavior of soils under repeated loading conditions. In Indonesia, particularly in mining areas where ground stability is a major concern, this test provides crucial data to ensure

Permeability Test: Definition, Methods, and Applications in Geotechnical Engineering Permeability tests play a crucial role in geotechnical engineering. They show how easily water or other fluids can flow through soil or rock layers. Therefore, understanding soil permeability becomes essential for planning construction projects, designing foundations, evaluating groundwater flow, and preventing geotechnical failures. What is a

Underground Landslide at PT Freeport Indonesia: Seven Workers Initially Reported Trapped A landslide hit PT Freeport Indonesia’s (PTFI) underground mine in Mimika Regency, Central Papua, on Monday, September 8, 2025, at around 22:00 local time (WIT). Heavy rainfall triggered the incident. At first, seven underground workers were trapped, raising serious concerns about safety in the

In geotechnical and environmental engineering, obtaining accurate soil samples is essential for reliable laboratory testing. One of the most effective methods is box sampling, which allows engineers to collect undisturbed soil samples while maintaining their natural structure. However, the accuracy of soil testing depends not only on the sampling method but also on how well

Construction in earthquake-prone regions requires more than strong materials and advanced designs—it demands the expertise of a geotechnical consultant in earthquake-prone areas. These specialists play a critical role in assessing ground conditions, mitigating seismic risks, and ensuring that infrastructure projects remain safe and reliable. Without proper geotechnical guidance, projects in seismic zones risk structural failures,

Hydrology and groundwater monitoring play a vital role in the success of mining, construction, and environmental projects. Without proper assessment of water movement and subsurface conditions, projects face risks such as flooding, contamination, or unstable ground. This is where geotechnical consultants become indispensable. Why Hydrology Matters in Projects Hydrology is the study of water movement,
