soil stabilization for miningAggreBind is a water based, environmentally friendly, cross linking copolymer that binds fine particles together to:

Reduce machinery maintenance costs,
Improve the Health of mine workers,
Provide safe roads to improve production,
Line drainage ditches and containment ponds,
Reduce environmental pollution,

Improve the efficiency and profitability of the mining operation.

Local Community Benefits

AggreBind provides an opportunity for local communities to manufacture bricks/blocks from on-site materials to provide sustainable self-help housing, schools, clinics, roads, etc. Local communities can also be employed to maintain mine access roads using only basic hand tools.

The key to this program is long term sustainability when the mining operations cease. It is vitally important that local communities are consulted, and receive help, in structuring any supporting long term ‘Collective Community Investment and saving structures.’


If the dumps contain steep slopes that a thin surface treatment could be subjected to reverse pressures from below.

If the area has heavy torrential rain then this could also damage a thin (3mm) surface seal.

There is a possibility that high winds could carry untreated material onto a sealed surface. Is there any on-going maintenance program for the treated dumps?

There is a possibility that the surface may have to be sprayed twice if the material is very fine and porous.

Containment dams for contaminated slurry


Ideally the site should be level with no history of flooding or earthquake activity. The dam can be any size but the side and end walls must be at an angle of +/- 45° or less.
The depth should not exceed 2 mtrs.
The depth of the stabilised walls and base will be determined by the depth of the dam.

1 mtr deep stabilized depth 100mm
1.5 mtr deep stabilized depth 125mm
2.0 mtr deep stabilized depth 150mm

Soil Type: Fine soils are preferable with virtually no stone content.

Soil stabilization for mining

Stabilizing Soil PROCEDURES:

Excavate the area of the dam.
Rip the surface to the required depth.
Spray with a mixture of 1 part AggreBind mixed with 4 parts water and mix this thoroughly into the soil.
Grade the surface and compact.
Spray the entire surface with a mixture of 1 part AggreBind mixed with 3 parts water.
Wait 3 days before filling the dam.
If required, a small test dam of 1 sq mtr can be made first to ensure that the slurry is being contained.
An additional advantage is that if the dam can be re-used a number of times if it is necessary to drain the dam to remove the solids content. Simply reseal the surfaces of the dam when it is empty.
It is recommended that the User perform local testing and obtain the necessary approvals and acceptance from the Authorities prior to implementation.

This effectively coats each fine particle with water based, traceable, environmentally safe,  cross linking copolymer that seals and binds all.
Samples are sprayed with a solution of 1 part AggreBind to +-3 to 7 parts water subject to material and requirements.

The mixture is applied at a rate that ensured that that the moisture content is at least 10% above Optimum Moisture Content.

The mixture is working thoroughly into the contaminated material to ensure that all the particles are fully coated.

The treated samples were then spread onto a clear non-absorbent plate and allowed to cure and harden at room temperature.

The treated cured samples were then immersed in water for 7-14-and 28 days.

There was no leaching, separation or softening of the treated samples.

EPA will draft standards for treating fracking waste water : Posted: 2:55 pm Thu, October 20, 2011 
By Associated Press

ALLENTOWN, Pa. — Federal environmental regulators signaled Thursday they want to increase oversight of the natural gas extraction industry, announcing they will develop national standards for the disposal of polluted wastewaters generated by a drilling technique known as hydraulic fracturing or fracking.

Energy companies have dramatically expanded the use of fracking in recent years, injecting millions of gallons of water, sand and chemical additives to unlock gas in deep shale formations in Pennsylvania, Texas and other states. Its prevalence has raised concerns about the potential impact on water quality and quantity.

There is interest in allowing fracking in Western Maryland and Gov. Martin O’Malley has ordered a study of best practices for drilling and production by August 2012 and a final report assessing environmental impact by August, 2014.

The Environmental Protection Agency announced that it will draft standards for fracking waste water — the briny, chemical-laced water that comes back out of the well — that drillers would have to meet before sending it to treatment plants. The industry in recent months has been recycling much of the waste water or injecting it deep underground, but some of it is sent to plants that are ill-equipped to remove the contaminants.

The new standards would also apply to waste water produced by coal-bed methane drilling, the agency said.

“We can protect the health of American families and communities at the same time we ensure access to all of the important resources that make up our energy economy. The American people expect and deserve nothing less,” said EPA Administrator Lisa P. Jackson.

EPA has largely left it to the states to regulate fracking operations, and environmental groups cheered Thursday’s announcement as a long-overdue first step. The agency is also in the midst of a national study of whether fracking has polluted groundwater and drinking water and its potential future impacts.

“The nation is in the midst of a fracking-fueled gas rush which is generating toxic waste water faster than treatment plants can handle it,” Earthjustice attorney Deborah Goldberg said. “The EPA’s proposal is a common sense solution for this growing public health problem and will help keep poisons out of our rivers, streams, and drinking water.”

Industry groups said waste water disposal is already regulated by the states, with one criticizing the EPA for overreach.

“Pennsylvania’s natural gas developers, as well as its regulators and service companies, are far ahead of EPA’s review of waste water treatment standards for shale gas,” said Lou D’Amico of Pennsylvania Independent Oil & Gas Association.

Drilling companies began flocking to Pennsylvania several years ago to exploit the Marcellus Shale formation, the nation’s largest-known reservoir of natural gas.

While drillers have expanded their efforts to recycle fracking waste water, the administration of Gov. Tom Corbett asked them earlier this year to stop sending millions of barrels of salty, polluted waste water to treatment plants that only partially remove the contaminants before discharging the water into rivers.
