地表水体可以是天然的(潮湖、海洋、河流或小河)或人造的(水库)。对于一定的地质和采矿条件,两种情况下岩层移动的模式是相同的。可以按照下列三种方式评价开采影响:1,水体周围的陆地下沉;2,防止地表水泛滥保证矿山安全;3、水库蓄水量的渗透损失。采矿引起陆地下沉,但下沉不一定改变水位。例如,潮湖水位大多受与之相连的海洋水位的控制。因此根据推断,当陆地出现下沉时,水位保持不变,结果是水将淹没下沉 Surface waters can be natural (tidal lakes, oceans, rivers or streams) or man-made (reservoirs). For certain geological and mining conditions, the pattern of rock movement is the same for both cases. The impact of mining can be evaluated in the following three ways: 1, land subsidence around the water body; 2, prevention of surface water flooding to ensure mine safety; and 3, loss of reservoir water infiltration. Mining causes land subsidence, but subsidence does not necessarily change the water level. For example, the water level in the Chaohu Lake is mostly controlled by the sea level to which it is connected. Therefore, according to the inference, when the land appears to sink, the water level remains unchanged, with the result that the water will submerge
