Aerial seeding bioremediation method for coal mining subsidence area

Abstract

The invention discloses an aerial seeding bioremediation method for a coal mining subsidence area. The aerial seeding bioremediation method for the coal mining subsidence area comprises the following steps: acquiring a topographic map of the coal mining subsidence area; performing gradient grading on the topographic map; determining an aerial seeding operation seeding coefficient according to a gradient grading result and the ground coverage rate of the coal mining subsidence area; determining height adjustment parameters in the aerial seeding process of a unmanned aerial vehicle; and performing aerial seeding operation by adopting the unmanned aerial vehicle according to the ground gradient grading result, the aerial seeding operation seeding coefficient and the height adjustment parameters. The slope grading aerial seeding technical standard determined by the aerial seeding bioremediation method for the coal mining subsidence area can adapt to a complex terrain of the coal mining subsidence area, and the safety of the unmanned aerial vehicle is guaranteed; the sowing amount is set in a grading mode according to the ground coverage rate, so that efficient and accurate sowing can be realized; the determined height adjustment parameters can ensure that the unmanned aerial vehicle always keeps an approximately equal vertical distance from the ground within a unit operation range; the unmanned aerial vehicle performs aerial seeding remote control operation, so that the influence of personnel entering the coal mining subsidence area on the environment is avoided, and the labor cost can be saved.

Description

technical field [0001] The invention relates to an aerial seeding bioremediation method in a coal mining subsidence area, belonging to the field of ecological restoration. Background technique [0002] The western part of my country is located in arid and semi-arid areas, and the ecological environment is fragile. Underground coal mining has caused rock formation and surface movement, disturbed the surface soil, and disturbed the growth of surface plants. The ecological environment in the coal mining area has a certain self-repair ability, but the natural restoration speed is relatively slow. How to quickly and efficiently restore the ecology of the coal mining area is the key to solving the environmental problems in this area. At the same time, there is a large degree of ground surface fragmentation after coal mining in underground mines, and there are even places that are difficult for people to reach, which limits the implementation of traditional artificial short-distanc...

AI Technical Summary

Problems solved by technology

However, in coal mining subsidence areas, the ground is broken and undulating. This environment limits the application and promotion of drone aerial seeding technology in vegetation restoration in coal mining areas, and seeding operations that do not consider slope and ground coverage will also waste seeds.
