Embodiment 1

[0057] The panel drying method provided in this embodiment includes:

[0058] S11 divides the mine into multiple panels;

[0059] S12 survey the groundwater recharge direction of the panel to obtain the groundwater recharge direction;

[0060] S13 uses the veins intersecting with the groundwater supply direction in the panel as the dredging and intercepting roadway.

[0061] In this embodiment, the panel is designed with multiple piercing veins intersecting with the groundwater supply direction of the panel (the extension direction of the piercing veins and the groundwater supply direction form an acute angle or an obtuse angle, or both are perpendicular), and the panel is closest to the groundwater supply direction The piercing vein is used as the dredging and intercepting roadway, and a draining chamber and a draining borehole are set in the roadway. The extension direction of the draining borehole is opposite to or intersects with the groundwater supply direction, and the ...

Embodiment 2

[0086] The panel drying method provided in this embodiment includes:

[0087] S21 divides the mine into multiple panels;

[0088] S22 survey the groundwater recharge direction of the panel to obtain the groundwater recharge direction;

[0089] S23 survey the ore body boundary of the panel to obtain the ore body boundary of the panel;

[0090] S24 survey the water-rich characteristics of the ore bodies in the panel to obtain the water-rich characteristics of the ore bodies in the panel;

[0091] S25 Combining the groundwater recharge direction of the panel, the ore body boundary of the panel and the water-rich characteristics of the ore body of the panel, carry out excavation design, so that at least one of the multiple mining roadways intersects the groundwater recharge direction ;

[0092] S26 Use one of the excavation roadways intersecting with the groundwater recharge direction as the drainage and interception roadway.

[0093] In this embodiment, the panel area is surv...

Abstract

The invention provides a method for draining panels, which is applied to mines mined upward in layers, including: dividing the mine into multiple panels; and draining and draining the panels. The panel area dehydration method provided by the present invention is designed only for the panel area. Compared with the traditional mine bed dehydration design, it has clear pertinence, the influence range of dehydration is small, the dehydration period is short, and the construction period is short. Compared with the middle section, the interception and dewatering of partial panels has a smaller dewatering intensity, shorter dewatering time, and less mine drainage pressure, which is conducive to timely mining operations in the panel.

Description

technical field [0001] The invention relates to the technical field of mining, in particular to a panel drying method. Background technique [0002] At present, the method of dewatering the mine is: according to the geological conditions of the deposit, the technical and economic conditions of mining and the requirements of the current regulations, use the drainage structures in the middle section such as the drainage and interception roadway, the drainage borehole, etc., to lower the mining area in advance before mining. The groundwater level is a technical measure to reduce the water level below the mining level, or below the allowable residual water head, eliminate flooding, and create conditions for safe and efficient mining operations. [0003] The existing problems are: there are many special dewatering projects, the construction difficulty is high, and the investment is large; the dewatering influence range is large, which has a great impact on regional water resource...
