FIELD: oil and gas industry.
SUBSTANCE: invention describes the production method of coal briquettes, containing the following process steps: screening of the charge coal from the coarse fraction; its mixing with the binder; briquetting; drying and packaging of the obtained briquettes, characterized in that the complex binder is used as the binder, it contains the aqueous solution of polyelectrolyte based on polyacrylimide with the increased molecular mass (more than 15 million amu), the non-ionique water-soluble surfactant - propylene glycol and humic preparation "Biogum".
EFFECT: production of strong and high-calorific briquettes, while reducing the drying time.
