The invention discloses a line paving method of a coal mining bracket. The line paving method of the coal mining bracket mainly comprises an external control line paving method on the coal mining bracket and a paving process protection method. The line paving method provided by the invention comprises the following steps of: protecting an external control line on the coal mining bracket by utilizing a spiral coil, and paving the external control line by passing through the inside of a bracket push and pull jack connection rod; meanwhile, protecting the external control line by using a line protection sleeve at the position of an opening of the bracket push and pull jack connection rod; and finally, paving a main control line into a cable groove of a scraper conveyor. The problem that the conventional bracket paving line damages the line under irregular motion of the bracket can be solved; and meanwhile, the main circuit is paved inside the relatively still electric cable groove for protection. The line paving method has the advantages of avoiding the bracket motion, protecting the line to the greatest extent and conveniently overhauling and maintaining the line.
