Embodiment
[0040] see figure 1 As shown in the figure, this embodiment provides an efficient mining method for a gently inclined thin ore body. The gently inclined ore body has an inclination angle within 30° and a thickness of 1.8m to 3m, which specifically includes the following steps:
[0041] S1. Divide the gently inclined thin ore body to be mined into several stopes, and the specifications of each stope are: the height is 30m, the width is 6-8m, and the length is within 80m; The stope 11 and the second stope 12) are used as the synchronous mining unit 1, and the uphill roadway 2 parallel to each other is arranged in the middle of each stope; the specification of the uphill roadway 2 is 2*1.8m.
[0042] S2, arrange the electric harrow chamber 4 in the outer side of the lower middle section roadway 3 located in the lower wall of the ore body, and install the electric harrow winch 6; the electric harrow chamber 4 is located in the middle position of the two uphill roadways 2 in the sy...
