Discussion on perfection of current standard of belt conveyor protection device
Wu Yujing
Abstract：With the wide application of wireless sensors,wireless belt conveyor protection devices have appeared in coal mines,but the current industry standard MT 872-2000"Technical conditions for belt conveyor protection devices used in coal mines"does not manage and require wireless belt conveyor protection devices.In order to facilitate the application of safety mark certification for belt conveyor protection devices by production enterprises and to facilitate the selection,procurement,and use of belt conveyor protection devices by coal mining enterprises,based on this standard,the technical requirements related to the wireless part of the belt conveyor protection de-vice were supplemented.Combining safety standard management requirements,the structure,composition and naming of the wireless belt conveyor protection device were described in detail,and the technical requirements and test methods of the wireless part of the belt con-veyor protection device were supplemented and improved from seven aspects:signal standard,response time,battery power monitoring,self-diagnosis,upload strategy,anti-interference ability and equipment protection level.
