Abstract

The invention belongs to the field of laser measurement and relates to a drill jumbo blast hole laser ranging and positioning method. A device used in the drill jumbo blast hole laser ranging and positioning method comprises an industrial laser ranging sensor, a laser target, a high-precision omni-directional cloud deck and a touch screen and PLC all-in-one machine. The drill jumbo blast hole laser ranging and positioning method is applied to drill jumbo blast hole positioning in a mine drilling and blasting method. The drill jumbo blast hole laser ranging and positioning method has the advantages that the positioning process is not affected by the actual fracture surface condition of a roadway, the blast hole position is accurately positioned, operation is easy, and working efficiency is high.

Description

technical field [0001] The invention belongs to the field of laser measurement, and in particular relates to a laser ranging and positioning method for a blast hole of a rock drilling jumbo. Background technique [0002] The drill and blast method is a commonly used method in mine production. Blast hole positioning and drilling are important processes of this method. Currently, the commonly used blast hole drilling is mainly completed by rock drilling rigs. [0003] Under normal circumstances, according to the design drawing of the blasthole project, the staff will mark the position of the blasthole with red paint on the section of the mine, and then operate the rock drilling rig to drill the blasthole. Due to the unevenness of the section of the mine road, the state of the section is very complicated, which affects the accuracy of the blasthole position, and is time-consuming and laborious. [0004] Cao Shijie proposed a laser positioning method in the document "Single-chi...
