A research has been carried out to investigate the effects of below sea level mining on the cement raw material quality of a limestone quarry located adjacent to the shoreline near Darica-Kocaeli-Turkey. Field studies involved rock mass characterization through discontinuity surveys performed at the working benches of the quarry as well as on the core samples, monitoring of groundwater levels, performance of water pressure tests, and in-situ hydrochemical measurements. Hydrogeological data suggest that the carbonate sequence forms a poor unconfined aquifer having hydraulic conductivity values ranging between 10(-6) m/s and 10(-8) m/s. In the quarry, water seepages can only be observed at the shear zones. Electrical conductivity profiles taken from the boreholes located at various distances from the shore line indicated the present position of the salt water wedge.
已开展一项研究，以调查海平面以下采矿对土耳其科贾埃利省达里察附近海岸线附近一处石灰石采石场水泥原料质量的影响。现场研究包括通过在采石场工作平台以及岩芯样本上进行的节理调查对岩体进行特征描述、监测地下水位、进行水压测试以及现场水化学测量。水文地质数据表明，碳酸盐层序构成一个渗透性较差的无压含水层，其水力传导率值在10(-6)米/秒至10(-8)米/秒之间。在采石场，仅在剪切带观察到渗水现象。从距海岸线不同距离处的钻孔获取的电导率剖面图显示了咸水楔的当前位置。
