草堂河流域煤系地层主要环境地质问题研究

Main geological environmental problems of coal-bearing rock series in Caotang River Watershed

草堂河流域上游广泛出露煤系地层,随着经济建设的发展,由采煤引起的环境地质问题日益显现。为能有效防范和应对该类地质灾害,在分析流域环境地质背景的基础上,论述了煤系地层滑坡、崩塌、塌陷、不稳定斜坡等主要环境地质灾害发育的规律,提出了煤系地层主要环境地质灾害的发育发展模式,指出人类经济活动的盲目性和不科学性是诱发地质灾害主要原因。研究成果可为其他流域煤系地层环境地质问题研究提供参考。

Coal - measure - strata are widely distributed at the upstream area of Caotang River Watershed. With the development of economic construction, the geo - environmental issues induced by coal mining appear. In order to mitigate the negative effects, the geological background of the watershed is analyzed and the main development laws and problems of landslide, collapse, subsidence, unstable slope in the watershed are illustrated, and the main development mode of above geo - environmental hazards are proposed accordingly. It is found that human activity is the main inducing factors for the geological disasters. The resuits can provide references for the researches on geo - environmental problems in other watersheds with coal - measure - strata.
