End face distance monitoring and intelligent control method based on coal mine digital geologic model

The invention discloses an end face distance monitoring and intelligent control method based on a coal mine digital geologic model. The method comprises the steps that the inclination angle of a top beam of a hydraulic support and the inclination angle of the top of a coal mining machine are obtained; the inclination angle of the top beam of the hydraulic support and the inclination angle of the top of the coal mining machine are processed, and the end face distance is obtained; the end face distance is compared with a preset end face distance, and if the end face distance is larger than or smaller than the preset end face distance, the coal machine is controlled to adjust the end face distance according to the relation of the top and bottom plate height change, the mining technology and the end face distance change. Through intelligent control over the end face distance, the problem of roof coal seam (or rock stratum) caving and collapsing caused by the too large end face distance is avoided, the coal mining
