Ecological Restoration Technology and Application of Open-pit Limestone Mine Based on Geomorphological Remodeling Scheme——Take the Ecological Restoration of Xiaozhai Limestone Mine in Lantian County as an Example
The high and steep rock slopes of open-pit mines are the focus and difficulty of ecological restoration,and most of the slope restoration technologies currently used have shortcomings in durability and adaptability.Based on the ecological restoration project of Xiaozhai limestone mine in Lantian county,this study proposed a landform remodeling scheme for step-type transformation,decomposing the rock slope with a height of 15m into two steps of not more than 8m,and planting trees+vines for vegetation restoration and shading,so that the treatment of the façade of the rock slope was simplified to plane treatment,which reduced the difficulty of restoration and improved the durability of the effect.The preliminary results of this study are that the parameter technology suitable for the application of geomorphological remodeling and planting technology on the high and steep rock slopes of wide stepped limestone mines.It is of great significance for promoting geomorphological remodeling and planting technology,and also for ecological environmental protection and high-quality development of mining.
