Water, drainage, and irrigation channels are vital components of infrastructure that impact many aspects of our lives. Building durable and efficient channels is key to addressing environmental challenges and supporting sustainable development. In 2019, in Segare village, Asmat Regency, Manokwari, West Papua, we were faced with a critical task: building an irrigation channel for a…
To date, blasting techniques using air decks have undergone significant development and attracted significant attention in recent decades. This is particularly true in efforts to improve blasting efficiency, reduce explosives use, mitigate blast-induced vibrations, protect the mine walls, and other aspects that undoubtedly provide extraordinary benefits to mining. An air deck is defined as a…
Indonesia is an archipelagic nation with abundant natural resources, including fertile agricultural land. However, one of the main challenges facing food security is efficient water management. Proper irrigation development can be key to successfully increasing food production. In this context, innovative technologies such as “Concrete Canvas” have emerged as modern solutions with the potential to…
In the mining world, every step is a challenge, especially when it comes to wet holes at blasting sites. Airdeck methods, often using gas bags and similar methods, are considered ineffective in wet holes. However, the advent of revolutionary airdeck technology from MTi GROUP, BLASTBAG™, has changed this paradigm. We offer a solution to this…
Dam projects in Indonesia play a crucial role in managing water resources, providing water for irrigation, energy, and drinking water supplies for communities. In this context, one of the most important aspects is the diversion channel system, which temporarily directs water from the river during the dam construction period. One of the latest innovations that…
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…
