摘要：

A brief description of coal resources in Transbaikalia is given. The issues of thermal and hydrochemical modification of coal from Apsat deposit are discussed. The usability of carbonization, gas-steam activation and alkaline treatment of low-caking coal for the improvement of coal adsorption capacity is determined. The proposed technology of Apsat coal preparation and dressing includes crushing, screening, carbonization and steam activation. The characteristics of the initial and treated coal are presented. The main physicochemical properties of the produced carbon adsorbents are determined. The coal modification parameters are identified. The computer-aided modeling of activated carbon adsorbents based on the quantum-chemical interaction of particles is described. The application areas of high-quality adsorbents in mining waste treatment are specified.
