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] In S13, the veins intersecting the groundwater supply direction in the panel area are used as the dredging and intercepting roadways.

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

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 at least one mining roadway as a draining and intercepting roadway.

[0093] In this embodiment, the panel area is surveyed to obtain the direction of groundwater sup...

Abstract

The invention provides a panel unwatering method. The panel unwatering method is applied to an upward slicing extractive mine and comprises the steps that the mine is divided into multiple panel areas; unwatering and drainage are conducted on the panel areas. The panel unwatering method is designed for panel area unwatering. Compared with a traditional mineral deposit unwatering design, the methodhas the advantages of definite pertinence, small unwatering influence range, short unwatering period and short construction period, the strength of closure unwatering of local panel areas is smallerthan that of middle-section unwatering, the unwatering time is shorter, the water drainage pressure of the mine is small, and timely implementation of mining operation of the panel areas is facilitated.

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...
