Generating system and method for high-precision three-dimensional navigation map of fully mechanized mining face

Abstract

The invention discloses a generating system and a method for generating a high-precision three-dimensional navigation map of a fully mechanized mining face, and is adapted for use in the technical field of unmanned mining. The generating system comprises a channel wave seismometer, a laser radar, a combined navigation device, a ground penetrating radar and a data processing unit. The data processing unit acquires data collected by various sensors and then conducts coordinate conversion, feature fusion and consistency processing for the acquired data to generate a Delaunay triangle network of acoal seam, a fault / fold and a roadway; draws a high-precision profile map of the triangle map, calculates a topological relationship of the profile map, generates a topological data structure of theprofile map, establishes a navigation information automatic query database platform based on the high-precision profile map, and constructs the high-precision three-dimensional navigation map of the fully mechanized mining face. The high-precision three-dimensional navigation map generated by the invention can provide accurate the thickness information of the coal seam, the varied dip angle of thecoal seam and the position of the dangerous geological structure space for the fully mechanized mining equipment, and has functions of high-precision positioning, information sensing and path planning.

Description

technical field [0001] The invention relates to a generation system and method, and is especially suitable for a generation system and method of a high-precision three-dimensional navigation map of a fully mechanized mining face used in the technical field of unmanned mining. Background technique [0002] Unmanned mining of coal mines is a cutting-edge technology commonly pursued by the international coal mining field. It is an important means to reduce casualties and ensure safe production, and it is also an effective way for my country's coal mines to achieve safe, efficient and green mining. At present, in working faces with relatively simple geological conditions and coal seam structures, unmanned mining can be realized by combining memory cutting and manual remote intervention, but most of the working faces in my country have very complex geological conditions and coal seam structures (such as coal seam There are large undulations, and there are dangerous geological stru...
