Ecological restoration method for coal gangue heap in karst area
The invention provides an ecological restoration method for a coal gangue pile in a karst area, which comprises the following steps of: trimming coal gangue in the karst area to eliminate the coal gangue pile and geological disaster hidden danger areas around the coal gangue pile, leveling a coal gangue pile platform until the slope gradient is less than 35-40 degrees, planting restoration plants in the coal gangue platform area, and preparing a coal gangue modifier. Paving one third of a modifier in the planting pit, then planting a repairing pioneer species or pennisetum sinese with economic value, finally filling the planting pit with the coal gangue modifier, compacting, and finally watering. Aiming at the problems of serious water and soil loss, difficult vegetation growth, poorer natural restoration, high artificial restoration cost, poorer effect, low economic benefit, landscape damage and the like of the coal gangue sloping field, the coal gangue in the karst area is trimmed, a coal gangue modifier is applied, restoration plants are planted, and vegetation restoration and ecological management of a coal gangue pile are realized. 25 tons of pasture can be harvested per mu every year, the value is 10,000 yuan, and the produced pasture meets the forage grass standard.
本发明提供了一种岩溶区煤矸石堆的生态修复方法，包括如下步骤：修整岩溶区的煤矸石消除煤矸石堆及其周边的地质灾害隐患区，整平煤矸石堆平台，边坡坡度小于35～40°，在煤矸石平台区种植修复植物，配置煤矸石改良剂，在种植坑内铺设三分之一的改良剂，而后种上修复先锋物种或者具有经济价值的巨菌草，最后用煤矸石改良剂填满种植坑后压实，最后浇水。本发明针对煤矸石坡地水土流失严重，植被生长困难，自然修复较差，人工修复成本高效果较差，经济效益低下，景观破坏等问题，对岩溶区的煤矸石进行修整，施加煤矸石改良剂并种植修复植物，实现煤矸石堆的植被恢复和生态治理。本发明每亩地每年可收割25吨牧场，价值1万元，生产出的牧草符合饲草标准。
