mining influence area

However, it is inevitable to decrease the groundwater level around the mining area and even to influence the water supply safety of the constructed groundwater source fields.

为保证矿区安全开采，采矿本身要求排出大量的矿井水，这不可避免地使附近的地下水水位下降，并可能影响到已有地下水水源地的供水安全，产生供、排水矛盾。

Economic factors, the main influence on the performance of this area as coal, iron ore mining will change the existing land use for urban villages and mining sites or other sites.

经济因素对本区的主要影响表现为煤矿、铁矿的开采将原有的土地利用类型转变为城镇村及工矿用地或其他用地。

The special surveying method of SAR system(side-looking imaging) and specific surface condition of mining area lead to many influence on high precision.

但由于SAR系统的测量方式（侧视成像），以及矿区的特殊地表情况，导致影响其测高精度的因素很多。
