Embodiment Construction
[0017] The following is based on Figure 1 to Figure 3 The specific embodiment of the present invention is further described:
[0018] see Figure 1 to Figure 3 , figure 1 There are 3 stopes in . This embodiment provides a ramp layout method applied to the stope of the upward layered filling mining method, including:
[0019] (1) When using the upward layered filling mining method to return to the ore body, on one side of the stope close to the ore body boundary or the mining boundary 5 to 10 meters away, the switchback ramp 4 is dug upward from the lower horizontal middle roadway 6, The slope of the ramp 4 is less than 20%, and it is connected with each stratum of the stope by a short connecting road 5; a scraper is used for slag removal.
[0020] (2) The ramp 4 is constructed section by section with the rise of the layered mining of the stope until it penetrates the upper horizontal middle roadway 7; the ramp 4 is used as one of the safety passages of the stope and the s...
