Abstract: Extensible belt conveyor is one main transport equipment used by fully mechanized mining team. This paper analyzed
technological improvement of block protection device, sealing coal device with belt end, signal control system, against running
device and moving car in extensible belt conveyor, and proposed that the improvement can effectively reduce the accident rate of
belt conveyor and improved economic efficiency of coal mine.

 Key words: belt conveyor; block protection; coal-sealing; running deviation; moving car
