      <abstract xml:lang="ru">
        <p>На Кайерканском месторождении проведено комплексное изучение изменения углей пластов X и IX (далдыканская свита Р) на контак­тах с дайками долеритов для выявления характера связи между масштабами интрузий и приконтактовых зон измененного угля, а также особенностей контактово-термального метаморфизма угля. На различных расстояниях от контактов с дайками прослежены изменения значений основных показателей угля: зольность, выход летучих, кало­рийность, содержание углерода, удельный вес, отражательная способ­ность, микротвердость.</p>

        <p>At the Kayerkanskoye field, a comprehensive study of coal alteration of strata X and IX (Daldykan Formation P) at contacts with dolerite dikes was carried out to reveal the nature of the relationship between the scale of intrusions and near-contact zones of altered coal, as well as the features of contact-thermal metamorphism of coal. At different distances from the contacts with dikes, changes in the values of the main coal parameters were traced: ash content, volatile yield, caloric content, carbon content, specific gravity, reflectivity, microhardness.</p>
