摘　　要：对新汶矿区协庄煤矿井田因取土、采沙和盗采防水煤柱等地表采掘引起的废弃地的充填复垦材料及技术进行了研究 .结果表明 ,协庄煤矿煤矸石可作为废弃地的充填复垦材料 ,风化煤矸石的矿物化学组成与矿区黄土相近 ,煤矸石的汞、镉、铅、砷、氟等有毒元素的含量不超标 ,并含有一定的可供植物吸收的养分 .实践证明 ,提出的煤柱盗采坑和取土、采沙坑的充填复垦技术 ,彻底治理了废弃地的水害和恶化的生态环境 ,取得了显著的经济、社会和生态环境效益 ,并为其他矿区解决类似问题提供了理论和技术方法 .The material and technique of filling reclamation were researched for the waste land due to excavation of soil,sand and water pillar in the earth's surface in Xiezhuang Coal Mine of Xinwen mining area. The results indicate that the waste in Xiezhuang Coal Mine can be used as filling material for land reclamation, the mineral chemical composition of weathered waste is similar to that of loess, the contents of mercury, cadmium, lead, arsenic and fluorine do not exceed Chinese standards, and it contains certain nutrient suitable for the plant absorbed. The practice proves that the techniques of filling reclamation put forward have harnessed water damage and worsened ecological environment of the waste land, made remarkable benefits of economy, society and ecological environment, and offered the theoretical and technical methods to solve the similar problems for other mining areas.
