What are the safety technical measures and matters needing attention when the belt conveyor is installed underground in coal mine?
Preparations before installation
1: Technical preparation
A: The geosurvey department is required to release the center line of the belt of the roadway and the center line of the drum of the belt head, and determine the height of the belt foundation. The center line of the belt should be given at intervals of 50 meters.
B: Prepare the belt installation technical documents.

After the belt frame is installed, the belt connector is made and connected with the cable and the middle belt is put on the shelf. When the main and auxiliary drum wear belt, first of all, the motor should be powered on, and then through the inching motor and manpower with wear the storage belt section belt.
3, the belt installation center line must be guaranteed to be in line with the measured belt center line, to ensure the installation quality. All belt buckles must meet the standard requirements when making belt joints.
3. Safety technical measures
1. Transportation method
5T electric locomotive and JD-11.4 winch with transportation, 5T and more than the large each time only allowed to hang a car, the rest of the small pieces can be string car transportation, but string car quantity each time is not more than 2 cars, must use φ18.5mm short rope buckle connected.
