Embodiment Construction
[0044] This embodiment is used as figure 1 The blasting displacement measurement of the blasting area of the open-pit mine shown. The ore deposits in the open-pit mine include granite, marble, gneiss, schist and other rock types. The ore deposits are complex and inconsistent in scale. Uranium-bearing granites often take the form of isolated islands. Surrounded by waste rocks. The step height is 7.5m, the hole diameter is 165mm, and the hole mesh parameter is 4.5×5.0m.
[0045] The specific implementation steps of this embodiment are as follows:
[0046] Step 1: Determine the initial ore and rock boundary line 1 in the blasting area according to the resource model obtained from mine exploration and geological cataloging; use the 3D mining software Datemine to open the mine geological model file, and use the ore grade as the standard for color distribution. No ore waste rock The ore blocks of different grades will show obvious color differences, so the initial ore-rock boundary li...
