With the increasing production tasks in the Tongluoshan Mine,the production area has also increased, and the wind current is short-circuited and the series connection is serious. In order to solve this problem,a mechanical interlocking damper is introduced to block and regulate the wind flow,and reduce the short cir- cuit and series phenomenon of the wind flow. The practical application shows that the damper is applied well under the Tonglushan mine,which can greatly reduce the occurrence of shunt short circuit and series phe- nomenon,and has good effects on reducing mine ventilation energy consumption and improving overall venti- lation efficiency.
