Abstract
The invention discloses a rainfall management and control system suitable for mine ecological environment restoration and treatment. The system comprises a plurality of rainfall management and control units arranged step by step from high to low according to mountain trends; the adjacent rainfall management and control units are connected through drainage facilities to realize step-by-step water storage; each rainfall management and control unit comprises a slag water storage body; the slag water storage bodies are located between a mountain slope tunnel face and a water control diversion dam; the water control diversion dam enables residual water generated after the slag water storage bodies are saturated to flow to the next rainfall management and control unit and a mine platform at the other side through the drainage facilities; transversely-arranged planting ridges are arranged on the ground surfaces of the slag water storage bodies at intervals; the table top of each planting ridge is of an inwards-inclined structure; enclosure ridges are arranged on the edge of the mine platform; grid-shaped slag flushing reduction ridges are arranged on the inner side areas of the enclosure ridges; and vegetation is planted between the slag flushing reduction ridges. The rainfall management and control system suitable for mine ecological environment restoration and treatment can reduce the occurrence of water and soil loss and debris flow natural disasters, improves the utilization rate of natural rainfall, and is suitable for the technical field of mine ecological environment restoration.
Description
technical field [0001] The invention belongs to the technical field of mine ecological environment restoration, and specifically relates to a precipitation control system suitable for mine ecological environment restoration. Background technique [0002] 1. Natural environmental conditions [0003] The Taihang Mountains in western Hebei have an average annual precipitation of 300-600 mm and an average annual maximum evaporation of more than 1100 mm, belonging to an arid and semi-arid climate. In particular, the distribution of precipitation is uneven. The precipitation is concentrated in the three months from late June to early September, accounting for 60%-70% of the total annual precipitation. The total precipitation in the other nine months only accounts for 30% of the total annual precipitation. -40%, resulting in frequent spring droughts. There is relatively a lot of rain in summer, but the rainfall is too concentrated, and most of it is lost in the form of surface ru...
