Water ecological restoration system for coal mining subsidence area

Abstract

The invention discloses a coal mining subsidence area water ecological restoration system which comprises a surface runoff collecting pool, a control system and stepped planting filter beds, the adjacent planting filter beds are communicated through pipelines, and the planting filter beds adjacent to lakes discharge water into the lakes through water outlet pipes. The planting filter bed far away from the lake is communicated with the surface runoff collecting pool through a water inlet pipe; the side wall of at least one stage of planting filter bed is provided with a landscape lighting lamp electrically connected with the power supply module, the top of a lamp post of the landscape lighting lamp is provided with a photovoltaic power generation panel connected with the power supply module, and the photovoltaic power generation panel is connected with the power supply module through a photovoltaic inverter; the control system comprises illumination sensors, a flow adjusting valve installed on the water inlet pipe and a controller, the controller is used for receiving illumination intensity collected by the illumination sensors, and when the average illumination intensity of all the illumination sensors is larger than preset illumination intensity and the flow speed of the water inlet pipe and the water outlet pipe is not changed, the opening degree of the flow adjusting valve is adjusted. The water yield of the water inlet pipe is increased.

Description

technical field [0001] The invention relates to an ecological restoration technology, in particular to a water ecological restoration system in a coal mining subsidence area. Background technique [0002] After the useful minerals are extracted, the original stress balance state of the rock mass around the mining area is destroyed, and after the stress is redistributed, a new balance is reached. During this process, the rock strata and the surface produce continuous movement, deformation and discontinuous damage (such as cracking, caving, etc.), and this phenomenon is called "mining subsidence". [0003] The current coal mining subsidence has caused great damage to the land use in the mining area, the components and functions of the landscape system, and agricultural resources. The topography, traffic roads, water conservancy facilities, and ecological environment of the mining area have been severely damaged; The normal development of the production and life of the surroun...
