针对高潜水位煤矿区采煤塌陷地稳沉后再复垦存在的复垦率低、复垦成本高、复垦难度大等问题,选取恒源煤矿某采区为研究对象,在分析采前地面地形特征的基础上,结合煤矿开采计划,对地表动态沉陷过程进行了模拟,并分析了煤炭开采影响下地面土地利用变化的动态过程。在沉陷情景模拟的基础上,将地表动态沉陷信息与地面原始地形信息结合,比较了各开采阶段无源复垦条件下的复垦耕地率,定量揭示了各阶段沉陷积水面积与复垦耕地面积之间的关系。

According to the low reclamation ratio, high reclamation cost, high reclamation difficulty and other problems existed in the reclamation after the mining s ubsidence stabilized in high potential water level mining area, taking a mining block in Hengyuan Coal Mine as a study object, based on the analysis on the ground topo graphy features before the mining operation, in combination with the mining plan, the simulation was conducted on the ground surface dynamic subsidence process and the utilization variation of the surface ground land under the influences of the coal mining operations was analyzed. Based on the simulation on the subsidence circumst ances, in combination with the information on the surface ground dynamic subsidence the surface ground original topography, the reclamation efficiency of each mining stage was compared under the reclamation conditions with non flling materials and the relationship between the ponding area and the reclamation land area at each st age subsidence was quantitatively revealed.
