Embodiment 1
[0033] A filling mining method for multi-layer gently inclined thin-medium-thick ore deposits. The multi-layered ore bodies of this deposit are produced in layered or quasi-layered parallel, with an inclination angle of 5~25°, a length of 224~670m in general, a slope extension of 87~204m, and a thickness of ore layer in general 0.81~5.54 m, the thickness of the sandwich layer is 5-12m. The ore rock of the deposit has good stability, and the engineering geological conditions of the mining area are of simple-medium type.
[0034] The specific steps of the filling mining method of the deposit are:
[0035] 1) Ore block division and mining and cutting engineering layout
[0036] ① Division of ore blocks
[0037] Divide the deposit into stages, such as figure 1 with figure 2 As shown, each layered ore body in the stage is divided into panels. An uphill 2 is excavated at the bottom of the ore layer 1 along the inclination of the ore body, and the ore bodies on both sides are divided int...
Embodiment 2
[0049] A filling mining method for multi-layer gently inclined thin-medium-thick ore deposits. The deposit is a horizontal to gently inclined multi-layer thin deposit, with an inclination angle of 0-18°, a strike length of 620-1100m, a tendency to extend 460-856m, the thickness of the ore body is generally 2.3-3.4m, and the thickness of the interlayer is generally 6~10m, the rock stability of the deposit is medium to good, and the engineering geological conditions of the mining area are simple-medium types.
[0050] The filling mining method of the deposit is the same as that in Example 1.
[0051] Compared with the prior art, this specific implementation has the following positive effects:
[0052] In this specific embodiment, each layered ore body is divided into panels, and the ore house 15 and the ore pillar 14 are arranged in a staggered manner, and multiple panels and multiple stopes can be mined at the same time. At the same time, the stoping and filling of different stopes ...
