    摘要:

    采矿对环境具有一定影响。辽西半干旱区和辽东半湿润区野外定点观测结果表明:矿区气温,夏季高于对照2℃-7℃,春秋季节低于对照区。矿业弃物堆(岩土)含水量低于对照6-11个百分点,在干旱期,岩土含水量仅为植物萎蔫含水量甚至更低。矿业弃物堆的蒸发量高于对照1-5mm,但矿区的空气相对温度却明显低于对照。由此说明,矿区环境条件迥别于周边环境,更趋于沙漠区的自然环境。

    Abstract:

    In the semi-arid area of western Liaoning Province and the semi-humid area of eastern of Liaoning Province, field observations showed that the temperature in a mining area was higher than CK in summer by 2℃ and 7℃ respectively, but below CK in the spring and the autumn. In the spring and autumn, the moisture content of the mining residue pile was 6% and 11% respectively, while the moisture content of the mining residue pile in the arid period was at wilting point or lower. Evaporation from mining area increased by 1-5mm compared with CK, but the humidity of mining area was much lower than CK.
