中文摘要：

排土场作为矿山重要的安全设施被广泛研究。针对我国冶金矿山排土场存在的稳定性、软弱地基排土、环境污染、机械化水平不高、评价结果与实际不符等主要问题,通过系统总结我国在排土工艺、稳定性、灾害防治、生态复垦等方面的研究成果,提出了包括多台阶覆盖式排土方式、逆排排土工艺、参数反演和空间效应稳定性分析等解决问题的方法。以此提出了我国冶金矿山在重金属污染治理、排土场与尾矿混排、智能化监测、多场耦合稳定性分析等技术研究方面的发展方向。

英文摘要：

Waste dump,the important safety facilities of mine,has been widely studied. Aiming at the existing problems in mine dumps, such as poor stability, soft soil foundation, environmental pollution, low mechanization level, and the evaluation result not fitting with the actual in our country, the researches on the dumping process, stability, disaster prevention and con- trol, ecological reclamation, are systematically summarized. And some solving methods are put forward,including the multi-step coverage dumping method,inverse dumping process, parameter inversion and space effect stability analysis. Therefore, some re- searches and development directions in the treatment of heavy metal pollution, waste-railings mixed dumping, intelligent monito- ring, stability analysis of multi field coupling technology in metallurgical mine in China are proposed.
