Abstract
Methods are described for maintaining unpaved roads. The methods include applying an aqueous composition to a section of an unpaved road (such as a mine haul road in a mine). The aqueous composition includes from 5 to 10,000 ppm of a synthetic polymer in water, and may be applied periodically. The synthetic polymer may be compatible with chemical processes employed by the mine, and the method may also include subsequently mining the section of the mine haul road.
Claims19
A method for maintaining an unpaved road, the method comprising:
- periodically applying an aqueous composition to a section of the unpaved road, the aqueous composition comprising from 5 to 10,000 ppm of a synthetic polymer in water.
A method for maintaining a mine haul road, the method comprising:
- applying to a section of the mine haul road a first application of an aqueous composition comprising from 5 to 10,000 ppm of a synthetic polymer in water;
- and
- after a time period in which there is no aqueous composition applied to the section of the mine haul road, applying to the section of the mine haul road a second application of the aqueous composition.
A method for maintaining a mine haul road used in a mine that employs chemical processes to extract a raw material, the method comprising:
- applying to a section of the mine haul road a first application of an aqueous composition comprising from 5 to 10,000 ppm of a synthetic polymer in water, the synthetic polymer being compatible with the chemical processes;
- after a time period in which there is no aqueous composition applied to the section of the mine haul road, applying to the section of the mine haul road a second application of the aqueous composition;
- and
- subsequently mining the section of the mine haul road.
A method for maintaining a mine haul road used in a copper mine, the method comprising:
- periodically applying to a section of the mine haul road an aqueous composition comprising from 100 to 1,000 ppm of a synthetic cationic polymer in water, the synthetic cationic polymer having a molecular weight of from 2,000,000 g/mol to 10,000,000 g/mol.
