Description

technical field [0001] The invention relates to a structure design method of an unmanned aerial vehicle, in particular to a multi-objective intelligent optimization design method for an unmanned aerial vehicle structure in a coal mine. Background technique [0002] At present, the distribution of my country's coal resources is characterized by insufficient shallow burial. Coal mining is gradually developing into deep development and utilization. The difficulty of mining is getting higher and higher, and the possibility of disasters such as gas outbursts and rock bursts is also increasing. When an operation accident occurs, timely and accurate detection of the underground environment and personnel after the disaster must be carried out. However, the complex production conditions in coal mines greatly increase the difficulty of detection and rescue; the traditional manual rescue strategy has a high possibility of secondary accidents and doubles the danger to mine safety hazard...
