Table 10
Erosion modulus (Ms) and runoff modulus (Mw) of slopes before and after mining with different slope types.
| | Slope type | Before mining | After mining | Variation | | Ms (t·km−2) | Mw (t·km−2) | Ms (t·km−2) | Mw (t·km−2) | Ms (t·km−2) | Mw (t·km−2) |
| | Concave slope | 9.877 | 1313.989 | 10.892 | 1444.352 | 1.015 | 130.363 | | Convex slope | 16.683 | 2207.331 | 19.063 | 2523.984 | 2.380 | 316.652 | | Mixed slope | 9.672 | 1287.193 | 9.682 | 1289.850 | 0.010 | 2.657 | | Uniform slope | 13.620 | 1803.354 | 14.295 | 1889.732 | 0.674 | 86.378 |
