Discussion on ecological restoration technology of planting holes in high and steep rock slopes
The exploitation of mining resources has greatly pro-moted the development of China's national economy,but at the same time,it has also caused serious environmental problems,forming many exposed high and steep rock slopes,causing dam-age to the ecological environment system.Planting boreholes is a new treatment technology for steep rock slopes proposed in recent years.Based on this,the ecological restoration technology of planting holes is studied through treatment cases.A planting hole with a diameter of 200 mm and a depth of 1m is used to repair and treat the mine,combined with rain collectors and shading nets as auxiliary facilities.The nutrient soil composition is rea-sonably configured,including planting soil,farmyard manure,wa-ter retaining agents,water,grass irrigation seeds,etc.Specific proportioning parameters are proposed to provide reference for similar projects.
