The effect of mining subsidence on soil bulk density, water moisture content, field capacity, saturated hydraulic conductivity and soil disintegration rate were studied based on field survey, sample collection and lab analysis in mining area of the Loess Plateau. The results showed: bulk density, water moisture content and field capacity of subsidence soil showed low to moderate CV, but saturated hydraulic conductivity and soil disintegration rate were high; soil bulk density was increased caused by mining subsidence, but the impact was little and there was not obvious rule on water moisture content; field capacity saturated hydraulic conductivity and soil disintegration rate significantly affected by the collapse (P<0.05), where field capacity decreased from 6.2% to 15.5% compared with undamaged areas; no significant difference was detected between reclaimed soil and undamaged soil (P>0.05), and differences among depths was also not significant(P>0.1).
