Treatment Measures of the Main Channel of Water Conveyance in the Coal Mine Goaf
YinheRiver Basin irrigation district,built in the last century,is limited by technical and economic conditions,and the water distribution project is arranged according to the principle of taking into account both water conservancy and coal mine.With the problems of foundation deformation,structure destruction and internal water leakage caused by the coal mine goaf near the main canal in the irrigation area,how to solve these secondary disasters in coal mines has become increasingly urgent.This paper draws on the thinking and experience of the main canal of the South-to-North Water diversion project to deal with the coal mine goaf,and combines the deformation,damage,and leakage of the irrigation canal over the years.This paper puts forward two treatment schemes of in-situ treatment and line migration according to the deformation,damage and leakage of the canal in the irrigation area for many years.
