Underground gold miners face challenges related to hole filling using the open-pit method. At certain times, the mine struggles to overcome water absorption and the degradation of the emulsion in the hole due to water. During the rainy season, the problem worsens with significant water inflow into the mine. During the rainy season, water can…
When it comes to toll road infrastructure, safety and sustainability are two crucial elements. One of the main challenges in toll road maintenance is slope protection, which must be maintained to prevent erosion or damage from weather, rainwater, or water runoff. One innovative solution that has been found to protect slopes on toll roads is…
In the world of blasting in mining areas, it’s possible to produce large, oversized chunks of rock, better known as boulders. Any large chunk of rock produced by blasting that cannot be adequately handled by standard digging and loading equipment used in mining operations is called a boulder. To prevent these boulders from disrupting productivity…
In conventional blasting, much of the blasting energy is lost and the optimal fragmentation size is not achieved. Large fragmentation can reduce the loading and unloading efficiency of mining equipment. According to Melnikov and Marchenko (1971), an air gap in the explosive column helps distribute the blasting energy throughout the rock mass. This significantly reduces…
Toll roads are a vital backbone of transportation in modern society. Proper maintenance is required to ensure road safety and smooth traffic flow. One of the problems often encountered in toll road maintenance is slope erosion. Landslides can cause serious traffic disruptions and, in some cases, even threaten the safety of road users. However, there…
MTi Group’s Collarcone Hole Savers are recognized as essential tools in drill and blast operations. Collarcone Hole Savers are a Collar Cone Protection product that protects blast holes before explosives are inserted. Collarcone Hole Savers are used to protect holes from exposure to rainwater and falling drill cuttings. Rainwater mixed with fine drill cuttings will…
Ponds containing acidic water often become a serious problem for the surrounding infrastructure. Damage caused by acidic water can deteriorate traditional pond lining materials in a relatively short period of time. However, our project in Sei Tohor, Riau, has proven that Concrete Canvas, an innovative material, can be an effective solution to overcome this issue,…
Landslides are one of the most frequent natural disasters in Indonesia. They can cause infrastructure damage, material loss, and even loss of life. One way to prevent landslides is through slope protection. Slope protection is a measure taken to prevent landslides. This can be done using various methods, depending on the condition of the slope…
Irrigation is a crucial factor in increasing agricultural productivity. It provides the water plants need for growth and development, resulting in healthy, high-quality, and productive crops. However, Indonesia’s irrigation network still requires significant modernization to ensure its effectiveness.. Irrigation is an effort to supply water to agricultural land using water from sources such as rivers,…
A Case Study of the Use of MTi BLASTBAG™ in an Open-pit Gold Mine in the Sonora Region, Mexico The condition and stability of final walls in deep open-pit mines are crucial not only for personnel safety but also for the overall economics of the mine life through the waste-to-ore ratio. A tendency toward instability…
