Abstract: In the rounded stock yard, the semiclosed space, the integrally explosion preventing for the electric control system of stackerreclaimer is a new topic. Aiming at the concrete situation of the rounded stock yard environment and the concrete features of the electric control system of the stackerreclaimer, the concrete explosion preventing measures for the stackerreclaimer electric control system were introduced. The necessity to adopt the pressurized electric room for the stackerreclaimer was analyzed. Combining with practical project, the design idea of the pressurized electric room and the problems needing attention in the pressurized electric room operation were expounded.

Key words: rounded stock yard, stacker-reclaimer, integrally explosion preventing, pressurized electric room
