Abstract

The invention discloses a strip mine dumping site based on platform catchment planting pits. A thick water-resisting layer is laid in the final construction forming stage of each step of the strip mine dumping site; a planting pit is dug in the thick water-resisting layer through a double-layer round sleeve; after the double-layer round sleeve is inserted into the thick water-resisting layer, the inner-layer sleeve and a water-resisting layer material in the inner-layer sleeve are taken out together, and the outer-layer sleeve is left in the thick water-resisting layer; paving a water storage layer at the bottom of the planting pit; after the water storage layer is laid, a soil cylinder is placed in the center in the outer sleeve; a gap is formed between the outer wall of the soil cylinder and the inner wall of the outer sleeve; the gap is filled with broken stones to form a water guide ring; and an evaporation retardant layer is laid on the upper surfaces of the thick water-resisting layer and the planting pits. The water storage layer and the water guide ring gather surface rainfall, and a local water-rich environment is provided for vegetation planting; most of surface rainfall enters the soil of the planting pit through the water guide ring, and soil salinization caused by migration and evaporation of fine particles in the soil due to natural infiltration of water is avoided.

Description

technical field [0001] The invention relates to an open-pit mine dump in arid areas, in particular to an open-pit mine dump based on a platform water-collecting planting pit. Background technique [0002] ‌Xinjiang, Gansu, Ningxia, western Inner Mongolia, northern Shaanxi and other regions in northwestern my country are rich in mineral resources, with a large number of open-pit mines distributed; at the same time, the region has arid climate, low annual precipitation, large evaporation, low vegetation coverage, primitive The ecology is fragile, and the high-intensity resource development further exacerbates the shortage of water resources in the mining area and the deterioration of the ecological environment. In recent years, with the deepening of the concept of ecological civilization, the contradiction between mineral resource development and ecological environmental protection has become increasingly prominent, and the government, enterprises and the public have paid more ...
