Soil and water loss is a kind of typical man-made accumulated erosion in mining area

whose erosion characteristics is distinctly different from previous landforms; ground subsidence resulting from pit-mining not only makes ground deform

slope steep and erosion degree serious

but has underground water quality polluted; Due to condensed surface and uneven subsidence

loose pile waste discharged by open-cast mining

prompts runoff to converge and leads to collapse and slope slide and debris flow etc

at the same time

increases mud and sand entering river making river course deposited and. making flood discharged difficultly. This paper elaborated characteristics of soil and water loss of subsidence and solid waste materials and its effect on sand entering river

discussed home and broad control measures including engineering measures and biological measures and dynamic monitoring model of soil and water loss

and research contents in future.
