Method for determining tracking spraying process parameters of fully-mechanized coal mining machine

The invention relates to a method for determining tracking spraying process parameters of a fully-mechanized face coal mining machine, and belongs to the field of dust falling processes. The coal cutter is driven by a roller to move and cut coal, a plurality of hydraulic supports are linearly arranged above the coal cutter, sprayers are uniformly arranged in the hydraulic supports, the number of groups of the sprayers in a working state is n, the coal cutting speed of the coal cutter is v, the spraying time is t, the spraying coverage length is l, the diameter of the roller is D, and the width of the hydraulic supports is H, by means of the geometrical relationship among the technological parameters, it is ensured that the coal cutter roller is always in the state of being wrapped by mist flow in the moving coal cutting process. By adopting the method, main process parameters such as the quantity of spraying and the spraying time when the coal mining machine tracks spraying and starts spraying can be quickly
