Unmanned helicopter-based mining subsidence monitoring method

Abstract

The invention relates to an unmanned helicopter-based mining subsidence monitoring method. The method comprises the following specific steps: 1) the route of the unmanned helicopter is planned according to the position of the mining area; 2) the mining area is monitored via remote sensing equipment carried with the unmanned helicopter so as to acquire a ground image of the mining area in real time; 3) when the unmanned helicopter monitors in the second step that a crack exists on the ground of the mining area, the unmanned helicopter is informed to go down to the crack position, and crack data are collected via detection equipment carried with the unmanned helicopter-; and 4) the ground slope of the area wherein the crack is located is detected via a slope detector carried with the unmanned helicopter. When the unmanned helicopter-based mining subsidence monitoring method of the above technical scheme is adopted, the mining terrain is monitored in real time via the unmanned helicopter, related data detection is carried out on the crack possible to appear in the mining area, and thus the subsidence situation of the mining area and subsequent possible changes can be judged correspondingly.

Description

technical field [0001] The invention relates to a disaster monitoring method, in particular to a mining area subsidence monitoring method based on an unmanned aerial vehicle. Background technique [0002] After the mining of mine resources, the original stress balance state of the overlying strata in the goaf is destroyed, and movement and deformation such as caving, fracture, and bending occur sequentially, and finally involve the surface, thereby forming the collapse of the mining area. The subsidence of the mining area not only has irreversible adverse effects on the natural environment, but also poses great hidden dangers to the residents of the mining area. The biggest manifestation of mine subsidence is the appearance of cracks on the surface. In the monitoring of mine subsidence in the existing technology, the location of cracks and related information are often obtained through field surveys by personnel. However, due to the large area and complex terrain of the mine...

Problems solved by technology

The subsidence of the mining area not only has irreversible adverse effects on the natural environment, but also poses great hidden dangers to the residents of the mining area.

The biggest manifestation of mine subsidence is the appearance of cracks on the surface. In the monitoring of mine subsidence in the existing technology, the location of cracks and related information are often obtained through field surveys by personnel. However, due to the large area and complex terrain of the mine area, manual operations cannot be effective. Comprehensive monitoring of mining areas
