Подходы, применяемые до настоящего времени для оценки процесса набухания угля , которые основаны на теории регулярных растворов, не дают возможность количественно обобщить экспериментальные данные. Соотношение между физико-химическими свойствами растворителей и степенью разбухания угля в них может быть получено только с использованием линейных многопараметрических уравнений, учитывающих влияние всех процессов, протекающих в системе; при этом основной и молярный объем жидкостей являются определяющими. Такой подход эффективен при обобщении данных, относящихся к добыче угля.

The approaches applying till the present time to the consideration of coal swelling process which are based on the theory of the regular solutions don’t give the possibility quantitatively to generalize the experimental data. An adequate relationship between physical−chemical properties of the solvents and coal swelling degree in them can be obtained only with the use of the linear multiparametric equations which take into account the effects of the all processes proceeding into the system; at that, the basicity and the molar volume of the liquids are determining. This approach is effective under the generalization of data concerning to the coal extraction.
