1. the monitoring method of mine Soil Erosion in Small Watershed modulus, it is mainly technically characterized ny:

  • Abandon the area monitoring'"'"'s method building experimental plot that " development construction item conservation technology specification " recommends, directly carry out the FR soil erosion monitoring of mine small watershed;

    By the draining that intercepts water, make mine small watershed form the hydrological environment of relative closure, rainwash in small watershed is directed to mining area downstream row Great Gulch;

    The turbidimetric analysis turbidimetry of sediment charge is carried out at the multiple batches of representativeness flood sample that extracts of tidal channel, and according to the full grain size analysis of small watershed soil sample, the Monitoring Result of flood sample is maked corrections, obtains year small watershed rainwash representativeness turbidity value, based on parameter;

    Arrive local meteorology again, Hydrology department checks in local annual rainfall, erosive rainfall amount proportionality coefficient and three parameters of surface runoff coefficient of quarrying landforms;

    The soil erosion modulus of mine small watershed then can be obtained by above four parameters.
