Embodiment
[0045] See figure 1 , figure 2 with image 3 , The figure is a schematic diagram of the internal structure of a mining area using a method of mining an inclined medium-thick metal ore body of the present invention. The specific mining implementation steps are as follows:
[0046] Step 1: Division of stope.
[0047] The ore body is divided into the stope along the direction of the ore body. The thickness of the stope is the thickness of the ore body, and the width of the stope is 10-15m. Because the ore body is inclinedly distributed, each stope in each section is close to the upper wall ore body and The footwall ore body is divided into upper triangle ore body and lower triangle ore body.
[0048] In the stope process, the stope is separated from one to the other. The upper triangle ore body is first recovered in the stope. After the empty area of the upper triangle is firmly filled, the lower triangle ore body is recovered. The height of the stage is 40-60m. Section, the sectio...
