田湖铁矿选厂尾矿坝坝体是就地取用含有10～20％石英砂岩块石的坡积及残积粘土、亚粘土建造的均质粘土坝,外侧建有渗水堤。坝体分三段成折线形,全长295.4米。主坝体长209.4米,最大高度20米,相应的坝基宽98.78米(图1)。坝体最低处有采用水泥砂浆砌块石墙,预制混凝土轨枕构顶,断面为0.8×0.6米~2,全长约100米的施工导流涵洞,导流涵洞上部有φ250毫米回水钢管。坝体内侧有间歇泉三处,均有盲沟与施工导流涵洞相通。坝内汇水面积约为0.29公里~2,库容积可达33万米~3。
Tian Lake iron ore processing plant tailings dam body is accessible on the spot with 10 to 20% quartz sandstone rock plot and residual clay, clay clay clay dam construction, built outside the water seepage dike. Dam into three sections into a straight line, a total length of 295.4 meters. The main dam is 209.4 meters long and the maximum height is 20 meters. The corresponding dam foundation is 98.78 meters wide (Figure 1). The lowest part of the dam is made of cement mortar block stone wall, prefabricated concrete sleeper top, section 0.8 × 0.6 m ~ 2, a total length of about 100 meters of construction diversion culverts, diversion culverts have φ250 mm backwater steel pipe. There are geysers within the dam three, both blind ditch and construction diversion culverts connected. Dam catchment area of about 0.29 km ~ 2, the reservoir volume of up to 330000 meters ~ 3.
