查询词典 mining area

D seismic and logging data of the first mining area in the Xinyi coal mine are dealt with impedance inversion to predict aquosity and watertightness of the top Ordovician limestone and the possible water-rich areas in the aquifer are determined by the impedance values.

本文根据新驿煤矿首采区的三维地震和测井资料，利用波阻抗反演技术预测该区奥陶系灰岩顶部的含隔水性，并依据波阻抗值的大小圈定含水层中的可能富水区。

Compared to wet season, arsenic is difficult to mobile in dry season. Attenuation constant in dry season is 0.3082(1/km), but it is 0.0569(1/km)in wet season. If initial concentration of As was 500μg/L without other contamination source in down stream, arsenic would deceased to 50μg/L in down stream 7.5km in dry season but 40km in down stream 40km. As is dominate species in river running throμgh mining area.

砷在枯水期较丰水期难以迁移，通过计算得到，在枯水期砷的衰减系数K值为0.3082(1/km)，而在丰水期为0.0569(1/km)；在污染口浓度达到500μg/L时，下游没有其它的砷的污染源(或会影响砷衰减的其它污染源)时，枯水期砷会在下游7.5km之后浓度降到50μg/L，而丰水期则要在下游40km之后才能降到同样的值，所以在丰水期砷污染的影响的流域更广。
