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 priorart 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.

Description

technical field [0001] The invention belongs to the technical field of mining, and relates to a simple ore-drawing method for mining a gently inclined ore. Background technique [0002] Under normal circumstances, when mining a gently inclined (18-35°) ore body, the 5# stope in the middle section of 575 in the Linghu Gold Mine in Jinyuan, Henan Province is used as the stope object, as shown in Figure 3 and Figure 4 As shown, the specific mining operation steps are as follows: (1) Ore block layout and constituent elements, the average thickness of the ore body is 2.75 meters, the average inclination angle is 29°, the bottom transportation level roadway 1 is 60 meters along the vein, and the natural ore pillar and artificial slurry are preset. The masonry pillars are left flexibly according to the grade of ore and the firmness of the roof, and the distance between the ore slides 10 is 10 meters; (2) mining and cutting work, excavating and cutting the uphill passage 5 and the p...
