煤矿区压占土地复垦适宜性评价研究——以贵州纳雍县狗场煤矿为例

Reclamation Suitability Evaluation of Occupied Land in Coal Mine Areas

复垦土地的适宜性评价是制定土地复垦方案的前提和基础。以贵州纳雍县狗场煤矿为例,结合矿区地形、土壤等实际情况,将该矿区拟复垦土地划分为生活区、生产区、储煤场、临时煤矸场、其他附属设施区等评价单元,确定各单元主要破坏类型为压占,破坏程度为重度;并参考耕地、林地适宜性评价指标,最终确定该矿区受压占破坏严重的评价地块复垦方向均为宜耕宜林地。

Reclamation suitability evaluation is the prerequisite and foundation to draw up a land reclamation program.Taking Gouchang coal mine for an example,combining with mine topography,soil and other practical situations,the mine area was divided into the living areas,coal storage yard,production areas,temporary coal gangue dump,subsidiary facilities district and other evaluation units.The results showed the main type in each unit was occupied,the degree of severe damage,and these unit areas can become to cultivated fields or woodlands.
