摘 要:羊场湾矿区在煤炭开采过程中形成了大面积沉陷区,并产生大量煤矸石,占地总面积65.82hm^(2)。因长期露天堆放,使矿区大量耕地、地面建筑物和地下水资源遭受破坏,矿区生态环境日趋恶化。本文首先通过对煤矸石化学成分、煤矸石边界有害物质及煤矿放射性进行检测,结果表明利用矸石充填沉陷区对土壤影响较小,且在技术实施上可行。其次,详细论述了煤矸石综合治理的措施。最后,分析了石煤矸回填后土地开发利用方向和治理效果。In the process of coal mining,Yangchangwan mining area formed a large area of subsidence area and produced a large amount of coal gangue,covering a total area of 65.82 hm^(2).Due to long-term open-air stacking,a large number of cultivated land,ground buildings and groundwater resources in the mining area have been damaged,and the ecological environment in the mining area is deteriorating.In this paper,the chemical composition of coal gangue,the hazardous substances at the boundary of coal gangue and the radioactivity of coal mine are detected firstly.The results show that the use of gangue to fill the subsidence area has little impact on the soil and is feasible in technical implementation.Secondly,the comprehensive treatment measures of coal gangue are discussed in detail.Finally,the direction of land development and utilization and the effect of treatment after the backfilling of gangue are analyzed.
