西南丘陵井工煤矿区破坏土地复垦措施分析——以贵州省黔西县青龙煤矿为例

西南丘陵地区煤矿的大面积开采对土地资源的破坏极其严重，如何解决煤炭资源开发引起的土地破坏成为该区土地资源可持续利用的关键。本文以西南丘陵区贵州黔西青龙煤矿为例，针对该区的自然条件、社会经济状况以及矿区土地破坏类型提出了矿区破坏土地的复垦措施。其中工程措施主要包括裂缝充填、土地平整、梯田工艺、排灌工程；生物化学措施主要有植物筛选、种植技术、土壤培肥与改良。通过以上复垦措施的实施来引导西南地区土地复垦工作的顺利实施，并为今后其他矿区被破坏土地的复垦工作提供参考。

APPROACHES TO REHABILITATION IN DESTROYED LAND IN JINGGONG COAL MINE IN SOUTHWEST HILLY AREA

A large area of mining in coal mines in southwest hilly area destroyed the land resource. How to restore the destroyed land plays a key role in the sustainable development of land resources in coal mines. This paper, based on a case study on Qinglong coal mine in western Guizhou province, presents approaches to rehabilitation according to the natural conditions, social economic development and the destroyed land types, of which the engineering approaches include filling fissures, leveling land, terrace, and drainage system, the bio-chemical approaches include vegetal selection, planting technology, soil fertilization and improvement. These approaches can be applied in southwest area for land rehabilitation, providing a reference in other mines.
