Provided is a foamed dust composition and a method of using the foamed dust composition. The foamed dust composition contains an aqueous foam comprising a foaming agent, a foam stabilizer, water, and a rock dust. The foamed dust composition is sprayed onto coal mine surfaces to prevent coal dust explosion in the event of a fire.

A method for using a composition for use as rock dust in an underground mine is disclosed. The composition includes a fine, wet ground inorganic particulate material treated with at least one hydrophobic treatment, and a coarse, untreated, dry ground inorganic particulate material. Also disclosed is a composition including coal dust and mine rock dust including a fine, wet ground inorganic particulate material treated with at least one hydrophobic treatment, and a coarse, untreated, dry ground inorganic particulate material. The amount of mine rock dust may be sufficient to render the coal dust explosively inert according to at least one of a 20-L explosibility test or an ASTM E1515 explosibility test. The fine, wet ground inorganic particulate material may be calcium carbonate. The coarse, untreated inorganic particulate material may be calcium carbonate. The fatty acid may be stearic acid.

The proposed invention is a process for obtaining the ore dust suppressant resin with the chemical recycling of Poly thermoplastic polymer (Ethylene Terephthalate) or PET. It is proposed a method for obtaining the resin by using the depolymerization reaction methodology of the Poly polymer (Ethylene Terephthalate) obtained from post-consumption PET bottles, in the presence of cationic surfactant hexadeciltrimetrilamonio bromide (CTAB).

The resin is thus obtained being subsequently added to the same PVP K-90 (Polyvinylpyrrolidone) as increasing load on the final viscosity of the resin. Other additives such as lignin extracted from plants such as leaves and tree branches may also be added, in this case, incorporated to make the resin more hydrophobic.

The invention provides methods and compositions for freeze conditioning particulating materials. The invention includes the use of the combination of crude glycerin with flowback or produced water. This combination prevents unwanted agglomeration when frozen. This combination also is non-corrosive and best of all facilitates the safe clean recycling of what would otherwise be unwanted dangerous waste material.
