Embodiment Construction
[0027] Such as figure 2 , image 3 , Figure 4 As shown, the open-pit mining process of rapid soil slope protection and ecological restoration includes the following steps:
[0028] (1) Use conventional methods to strip the waste rock at one end or the middle of the ore body, discharge the waste rock to the outer dump site, and mine the stripped ore body to form a minimum size a (generally 50- 100 m) of the initial stripping face 4 (such as Figure 5 , Figure 6 , Figure 7 shown);
[0029] (2) In the direction of mining and stripping, the stripping area is divided into left side area 1, middle area 2 and right side area 3 (such as Figure 8 shown), under the condition of meeting the minimum size required by the stripping operation, divide each zone into 2-1000 segments, such as Figure 8 As shown, every advance of 100-200 meters is a subsection, starting from the initial mining and stripping working face 4 as the first subsection 5;
[0030] (3) Firstly carry out the...
