FIELD: mining industry. SUBSTANCE: this can be also used in other branches of economy for removing exhaust gases emitted by internal-combustion engines from required territory without releasing exhaust gases to atmosphere. According to method, exhaust gases are collected in vessels of changing volume. This is achieved by connecting these vessels to exhaust system of engine with subsequent release of collected gases to atmosphere beyond quarry. Each of vessels with changing volume is filled with exhaust gases, then closed and taken out of quarry independently from other vessels. Aforesaid method ensures technologically simple and ecologically clean removing of exhaust gases from quarry space and others. EFFECT: higher efficiency. 2 dwg
