AI Technical Summary

Benefits of technology

This innovative design allows for two purposes: ① It improves the efficiency at moving materials over long distances without requiring expensive infrastructure or equipment; it makes mineral extraction more efficient while reducing labor requirements compared with current methods like tunnels used during excavations on steep slopes. Additionally, this new method reduces material handling time and energy consumption compared to traditional ways such as trucks and rail cars.

Problems solved by technology

This patented technical problem addressed during the process described in the patents describes how underground mines use different methods or arrangements to create stable paths that allow vehicles like cars to travel safely without getting stuck due to excessive rocks on their tracks.

Embodiment Construction

[0013] Figure 1 and figure 2 As shown, with the 450-meter middle section 3# gold mine stope as the stope object of the present embodiment, the middle part of the cutting uphill passage 5 communicates with the cutting roadway 3 in the horizontal direction, and the cutting uphill passage below the cutting roadway 3 is cut by the bottom engineering. The uphill slope a of 5 increases to 40-90 degrees. The bottom of the cutting uphill passage 5 communicates with the bottom transportation level roadway 1. The bottom of the cutting uphill passageway 5 is provided with an ore-drawing funnel 6. The ore above the cutting roadway 3 is cut up the mountain Passage 5 is released by ore-drawing funnel 6.

[0014] The specific mining operation steps are as follows: (1) Ore block layout and composition elements, the average thickness of the ore body is 2.90 meters, the average inclination angle is 27°, the bottom transportation level roadway 1 is 53 meters along the direction of the vein, and...

Abstract

The invention discloses a method for simply ore drawing of a low-dipping mine, which comprises the steps of communicating the middle of a cutting uphill passage along a mine vein in the low-dipping mine with a horizontal cutting road to increase uphill slope of the cutting uphill passage under the cutting road to be 40 to 90 degree, communicating the bottom of the cutting uphill passage with a bottom transport roadway, and drawing the mineral mined above the cutting road out through the cutting uphill passage. The ore drawing method avoids orepass and passing vein for ore drawing in the prior art as well as the construction amount of the same, the construction cost can be saved by twenty thousand Yuan with cutting uphill passage under each cutting road as a running chute, and also saves work time, thereby greatly reducing the construction cost and achieving certain economic benefits.
