[0020] In the following, with reference to the accompanying drawings, through the description of the embodiments, the method of the present invention for creating the conditions for dumping in the open-pit mine will be further explained in detail.
[0021] As shown in the figure, the Gushan iron deposit is shallowly buried, and the west wing extends relatively large, while the east wing extends relatively shallow; it is a semi-annular in the horizontal direction, and the south is broken by rock mass. Therefore, the designed minimum mining elevations at the east and west ends of the open-pit boundary are different. The eastern minimum mining elevation (H 1 ) -106m, the lowest mining elevation in the west (H 2 ) -166m.
[0022] According to the current state of mining in the Gushan quarry, if the east and west ends are mined at the same time, the stripped rock and soil will have no place to drain. Therefore, the stripping position of the stope is optimized and adjusted, and the east...
