Erosion Prevention

Please thank Google Translator for this English version.

Areas that have been exposed to openings and mining activities, are very common with erosion due to loss of cover vegetation that retains sediment and run-off water. In addition, mining activities can lead to changes in land structures into areas with higher erosion potential than before even with landslide potential due to steeper land slope changes.

In controlling erosion and sediment due to land clearing, we use various technologies and methods to create barriers or barriers to reduce the resulting erosion energy adjusted to the conditions of the land contained in the work area. Some of the techniques we use and their functions are:

  1. Jute net, coir blanket, use of coconut fiber (coco fiber); to filter and retain deposits flowing with the flow of water on the soil surface
  2. Bamboo fence, Rock Check Dam; in addition to resisting the precipitate that flows with surface water, also serves to maintain the surrounding soil structure. Sometimes also used wooden fences for soil structures that are steeper and have a high potential of erosion or even landslides.
  3. Closure by using hay mulch, which serves to resist the lifting of sediment from the surface due to the flow of water and wind, also serves to hold some of the soil moisture to avoid terevaporasi resulting from exposure of the soil to sunlight.
  4. There are several other techniques that we use that depend heavily on the state of the work area. The use of techniques for erosion and sediment control is also discussed to suit the client's wishes and expectations.
