FIELD: mining.
SUBSTANCE: during the preparation of the next horizon zones of intensive heat exchange in rocks are created in the form of blocks of active climatic influence (ACI blocks) by passing of the roadways serving for the creation of an additional exposed surface of the ACI block. Depending on mining conditions of the field the blocks are arranged lengthways or perpendicular to the direction of development of the front of mining operations. Parameters of the blocks, time of their run are determined taking into account the temperature and climatic characteristics of the area of works, thermophysical properties of rocks, characteristics of mining equipment in interrelation with the degree of weakening of the massif of rocks in the block.
EFFECT: increase of the intensity of heat exchange in rocks.
