矸石山基质改良技术初探
Preliminary Study on Matrix Improvement Technology of Gangue Hill

在矸石山生态修复工作中最为主要的内容是土壤构建，确保矸石山能够成功修复的第一步是解决基质问题。为此，本文从客土喷播、土工格室坡面恢复技术、客土改良等方面对河北峰峰集团煤矸石山基质改良进行了探究，结果表明3种方法均可以明显提高植被的覆盖率，加快植被恢复速度，为各类矸石山的基质改良提供了模式参考。
It is necessary to construct “soil conditions” for plant growth in ecological treatment of coal waste piles. Soil construction is the core content of ecological restoration of coal gangue. The successful restoration of coal gangue needs to solve the matrix problem first. Therefore, this paper explores the matrix improvement technology of coal gangue dump from the aspects of spray seeding, geocell slope restoration technology, and foreign soil filling. The results show that the three methods can significantly improve the vegetation coverage rate and speed up the vegetation recovery speed, which provides a model reference for the basic material improvement of various gangue hills.
