摘　　要：本文通过对大柳塔煤矿区环境地质问题的调查研究,分析评价了塌陷区的生态地质环境效应。指出截止2005年7月,大柳塔煤矿区累积形成采空区面积42.69km2,地表塌陷影响面积48.23~54.64km2,长臂式综采技术导致地表塌陷形成的地貌与原始波状地貌不易区分,地面塌陷对农业生产的影响相对较轻;对地表水水域面积、地下水水位影响最为显著,成为采煤塌陷区最大环境负效应。但由于各种原因采煤塌陷区没有出现土地沙漠化加剧的景观。妥善安置塌陷区较为稀少村民、确保重要水源地不被破坏和塌陷区土地沙漠化不恶化的情况下,最大程度地开采煤炭资源,实现地区经济发展和环境效益的统一。Based on researching on the problems of environmental geological in Daliuta coal mining area the paper analyzed environmental effect about the coal surface collapse.Cumulate mined-out area had gotten to 42.69km2 by the end of the july 2005.Its influencing area for the earth＇s surface was 48.23~54.64km2,It is difficult for investigators to distinguish two knd of physiognomies between the primordial physiognomy and the pbysiognomy of the coal surface collapse by fully mechanized mining technology.The effect for agriculture was not important,but was very remmarkable for the area change of surface water and the drawdown declinling degree of groundwater.This changes for water resource were the main negative effect in Daliuta coal mining area.The deteriorism trend of the soil desertification in mining area was not appearance.On these conditions of proper installing the villager bound coal surface collapse,proteeting important waterhead and lightening the soil desertification in coal surface collapse.Pesople can furthest develop coal resource and come true the aim about the economic development and environmental protection.
