Embodiment Construction
[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0031] Such as figure 1 , figure 2 , image 3 As shown in Fig. 1, an open-stop and then-fill mining method suitable for gently inclined medium-thick ore bodies includes the following steps:
[0032] Step A, divide the ore body along the vertical direction into the middle section of mining, the height of the middle section is 30m, leave a slanted top column between the two middle sections, the thickness of the slanted top column is 5m, in each middle section, along the direction of the ore body Divide the mining panel area, the length of the mining panel area is 100m~200m, leave a panel interval column 1 between the adjacent mining panel areas, the thickness of the panel interval column 1 is 30m, and divide the mining room every 15m in the mining panel area 2. Ore pillar 3, mine room 2 and ore pillar 3 are of the same size;
[0033] Step B. Approve engine...
