Mine route planning method, device and equipment based on digital twinning and medium

The invention provides a mine route planning method and device based on digital twinning, equipment and a medium, relates to the field of road planning, and can set a plurality of equal-height values at equal intervals between the height value of a preset starting point and the height value of a preset terminal point in a three-dimensional mountain model. Writing the coordinate points of which the height values are equal to the equal height values in the three-dimensional mountain model into equal height point sets corresponding to the equal height values; then, a horizontal planning area can be arranged between a preset starting point and a preset ending point, and coordinate points, located in the horizontal planning area, of horizontal coordinates in the equal-height point sets are written into candidate point sets corresponding to the equal-height values; furthermore, planning points can be determined in each candidate point set according to a preset gradient value, so that the condition that path gradien
