我矿回收品位较高的尾矿时，需使用一台2DPJ－30型电耙绞车耙矿。由于安装地点是属于1类上壤的粉砂尾矿，而且扒矿角度范围大于120o，为此，我们设计了一种环形基础，如附图所示。在安装地点，按电耙绞车原设计基础长度为直径划圆，以此图为外圆浇灌一个宽度为350mm的环形基础
When mine tailings with higher grade, we need to use a 2DPJ-30 electric rake winch mine. Because the installation site is silty tailings belonging to the 1st class, and the beating angle range is greater than 120 °, we designed a ring foundation, as shown in the attached figure. In the installation site, according to the original design of the rake winch length of the original design for the diameter of the circle, as shown in this picture is a circular cylindrical watering width of 350mm
