Coal gangue vegetation ecological restoration method
The invention discloses a coal gangue vegetation ecological restoration method, which is applied to the technical field of coal gangue ecological restoration, and is characterized by comprising the following steps: step 1, designing a coal gangue mountain into a stepped structure, setting the width of a step to be 1-1.5 m, the terrace fall to be 3-4.5 m and the slope angle to be 35-40 degrees, planting a vegetation blanket on the slope of the coal gangue mountain, and planting the vegetation blanket on the slope of the coal gangue mountain; the slope toe is of a concrete net structure, and an isolation layer is arranged in a gap between the slope toe and the ground. Step 2, pouring a treating fluid into the acidic mineral water in the coal gangue mountain, then spraying oxalic acid on the surface of the coal gangue mountain so as to generate an oxygen barrier film of 3-4cm on the outer layer of pyrite, and coating the surface of the coal gangue mountain with a mixture of sludge and yellow mud; the method has the technical effects that the influence of the acidic waste mineral water on the surrounding ecological environment is reduced, so that the ecological restoration effect of the coal gangue is better.
本发明公开了一种煤矸石植被生态修复方法，应用在煤矸石生态修复技术领域，其技术方案要点是：步骤一、将煤矸石山设计成台阶式结构，台阶的宽度为1~1.5m，梯田落差为3~4.5m，边坡角倾斜设置为35~40°，在煤矸石山的边坡上种植植生毯，坡脚采用混凝土网结构，在坡脚与地面之间的间隙设置隔离层；步骤二、向煤矸石山内的酸性矿水中倒入处理液，接着在煤矸石山的表面喷洒草酸，使黄铁矿外层生成3~4cm隔氧薄膜，将淤泥与黄泥巴的混合物涂覆在煤矸石山的表面；具有的技术效果是：减少酸性废矿水对周围生态环境的影响，使得煤矸石生态修复效果更好。
