为了增加塌陷区耕地资源，有效地提高土地利用率，减少环境污染，本文通过对海孜煤矿塌陷区进行实地勘查，室内测试和实验，分析塌陷区煤矸石充填复垦条件。分析结果表明：塌陷区的地形地貌条件有利于土地复垦工程的实施，较高的地下水位可以为重构土壤提供充足的水分；塌陷区塌陷深度小，且绝大部分塌陷区已达到稳沉状态，有益于煤矸石充填复垦；大量的煤矸石为充填复垦提供了充足的物质基础，煤矸石中有害元素含量低，复垦后不会对地下水和土壤造成显著的污染，且煤矸石的块度组分有利于水分的保持和上移。

In order to increase farmland resources in the depression area, effectively improve land use rate, and reduce environmental pollution, this paper analyzed reclamation conditions by filling of coal gangues in the area based on a site survey and lab test. Analytical result indicated that the landform conditions in the depression area are favorable to implementation of land reclamation program, higher groundwater level can provide adequate water for reorganization of soil; shallow depth of depression and majority of the area in a state of stable depression are helpful to filling with coal gangues for reclamation; massive coal gangues lay a solid material basis for the work, low content of harmful elements in the gangues would not cause remarkable pollution to groundwater and soil after reclamation, and the size and composition of gangues are good to retaining and moving-up of water.
