In view of the characteristics of the roadway and the particularity of the field environment of the non-pole rope continuous traction vehicle for coal mine, in this paper, a new type of wireless signal emergency stop control box for coal mine is introduced. The control box sets hoist signal, emergency stop control, voice communication, wireless communication and sound and light alarm functions in one, and can show the emergency stop, tapping numbers, and the number of the boxes, which is more effective to help staff find fault location and take the appropriate measures. Tested by experience, results show that control box is not only reliable to complete the traditional emergency stop control management, emergency stop, voice call functions, but also can display the number of the boxes and tapping numbers.
