开展煤矿区构造环境类型划分是提高采煤沉陷预计精度的有效途径。将影响采煤沉陷地质因素总结为构造介质、构造界面、构造形态和构造应力4个因素，在此基础上探讨了煤矿区构造环境的内涵，确定了煤矿区构造环境类型分类的指标。认为煤矿区构造环境突出采煤沉陷灾害发生的地质构造背景是地质环境的重要组成部分，更多地反映着地球的内动力地质作用。按照构造介质的不同，把煤矿区构造环境划分为浅埋介质型和深埋介质型；按照构造界面的不同，将其分为连续型、似连续型和不连续型；按照构造形态的不同，将其划分为近水平型、倾斜型和褶皱型；按照煤矿区构造应力的性质，把煤矿区构造环境划分为自重应力型、挤压构造型和拉张构造型。以铜川矿区为例，对煤矿区构造环境类型做了划分，铜川矿区以 A 型构造环境为主。

To carry out the type division of the tectonic setting in coal area is an effective way to improve coal mining subsidence prediction accuracy. The geological influence factors of coal mining subsidence are summarized as four factors: structural medium, fractures, structural shape and tectonic stress. The connotation of tectonic set-ting is studied, and classification index of tectonic setting in coal area have been defined on this basis. Tectonic setting in coal area highlights the geological structure background of mining subsidence disaster, which is an im-portant part of geological environment and reflected the geologic process of internal force more clearly. Based on the difference of structural medium, tectonic setting in coal area is divided into shadow medium type and deeply buried one. Based on the difference of fractures, tectonic setting in coal area is divided into continuous type, quasi-continuous type and discontinuous one. Based on the difference of structural shape, tectonic setting in coal area is divided into horizontal type, declining type and fold type. Based on the property of tectonic stress, tectonic setting in coal area is divided into self-weight stress type, compression tectonic stress type and tension tectonic stress type. Tectonic setting in coal area is divided by taking Tongchuan mining area as an example.
