Application of Geosynthetic clay liner in mineral waterproofing

Geosynthetic clay liner is a new type of geosynthetic material. It is made of natural sodium bentonite, and the bentonite particles are fixed between two layers of geotextile to make a bentonite waterproofing blanket, which not only has all the characteristics of geotechnical materials but also has excellent waterproofing (permeability) properties. It is often used in mineral waterproofing projects, so what role does it play in mineral waterproofing projects? The following is a specific description of the geosynthetic clay liners we produce.

The following is a list of contents:

• Geosynthetic clay liner for surface waterproofing

• Geosynthetic clay liner for underground waterproofing

Geosynthetic clay liner for surface waterproofing

To prevent water from surface water sources from gushing or seeping into mines. To prevent surface water (especially flash floods) from entering the mine site, we use various measures such as the construction of surface drainage control projects, filling and plugging of collapsed areas and depressions, river training, water isolation, seepage control, etc. We use geosynthetic clay liners as a substrate for waterproofing, and to prevent surface water (especially flash floods) from entering the mine site, we intercept surface flowing water by lying flat at the edge of the mine site in the direction of incoming water; we fill cracks, abandoned shafts and boreholes in collapsed areas with clay or cement to prevent the formation of channels for surface water to enter the mine site; constructing drainage ditches in collapsed areas and depressions prone to water accumulation, or filling and compacting with a geosynthetic clay liner and raising it above the surface; installing pumps to drain large collapsed areas and depressions that cannot be filled. 

When the river or river bed flowing through the mine site is highly permeable and river water may infiltrate into the mine site in large quantities, an artificial river bed may be constructed or the river may be diverted. When the surface water of rivers, lakes, reservoirs, and ponds cannot be drained or diverted and it is not appropriate to divert or relocate them, a geosynthetic clay liner can be laid on the surface to isolate the gushing water channel and prevent surface water from entering the mine site.

Geosynthetic clay liner for underground waterproofing

In the development of underground water sources in the mine, groundwater will gush into the mine in large quantities, we have to determine the water source, explore the water forward, block the water source, release the water dry at the same time, measure the amount of geosynthetic clay liner; identify the water source investigation to understand the permeability of the aquifer being mined, the water situation in the old hollow area, the distribution of faults and fracture water, the top plate broke when mining and surface settlement, etc., to take the appropriate waterproofing measures. Blocking water includes isolation of water and blocking water flow two kinds of measures. The former is used to isolate the mine (rock) column, and establish a waterproof curtain to isolate the water source to prevent water intrusion into the mine; the latter uses waterproof materials to intercept permeable water flow, once the permeable accident uses a geosynthetic clay liner to control the water damage within a certain range.

The expansion index, ethylene blue absorption rate, tensile strength, and shelf strength of our geosynthetic clay liners are better than most of the same type of materials in the market. Mineral waterproofing has an important impact on nature as well as mankind, and choosing quality materials is the key.
