摘要：为确保矸石山安全平稳投入使用,开展矸石山填沟造地生态技术实践及应用。充分利用原矸石山堆存的矸石,将矸石与肥料等混合成种植土,采用10 mm煤矸石作为造土原材料,在最佳掺配比例(煤矸石、有机肥、木屑配比为5∶1∶1)的前提下,植被存活率达到99%以上;经后期试验得出,铺设厚300~500 mm的人造土前,先铺设厚100 mm粉煤灰作为保水层,最终将种植土覆盖于生态恢复区域后种植存活率高的植被,实现矸石山生态恢复,有效解决矸石山堆存压力,加快矸石山生态恢复工作进度,同时开辟了矸石利用的新路径,可为矸石山的治理提供理论和实践经验。
In order to ensure the safe and stable use of gangue mountain,practice and application of ecological technology of land reclamation by ditch filling in gangue mountain were carried out,by making full use of the gangue stored in the original gangue mountain,mixing gangue with fertilizer into planting soil,using 10 mm coal gangue as the raw material for soil making,under the premise of the optimal mixing ratio:coal gangue∶organic fertilizer∶sawdust=5∶1∶1,the vegetation survival rate reached more than 99%,and after later tests,it was finally concluded that before laying 300~500 mm thick artificial soil,100 mm thick fly ash should be laid as a water retaining layer.Finally,the planting soil should be covered in the ecological restoration area and vegetation with high survival rate should be planted to achieve ecological restoration of the gangue mountain.This effectively solves the pressure of gangue storage,accelerates the progress of ecological restoration of the gangue mountain,and opens up a new path for gangue utilization,providing theoretical and practical experience for the treatment of the gangue mountain.
