Embodiment Construction

[0026] In order to make the technical solutions and advantages of the present invention clearer, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0027] figure 1 It is a flow chart of the method for treating mine water in the embodiment of the present invention.

[0028] like figure 1 As shown, the method for treating mine water in the embodiment of the present invention includes the following steps:

[0029] Step 101, at a preset position on the ground above the roadway, drill a water injection hole underground that passes through the roadway and reaches the water storage target layer, and sets a casing in the water injection hole while drilling the water injection hole;

[0030] Step 102, setting a water stopper at a position in the casing that is lower than the bottom of the roadway;

[0031] Step 103, a through hole is arranged on the side wall of the casing at the roadway, a control ...

Abstract

The invention provides a method for treating mine water, which comprises the following steps of: punching a water injection hole which penetrates through a roadway and reaches a water storage target layer to the underground at a preset position on the ground above the roadway, and arranging a sleeve in the water injection hole while punching the water injection hole; a water stop plug is arranged at the position, lower than the bottom of the roadway, in the sleeve; a through hole is formed in the side wall of the sleeve at the roadway, a control device used for controlling the through hole to be opened and closed is arranged at the through hole, and a pressurizing device is arranged at the input end of the control device; and the water stop plug is taken out, the orifice of the water injection hole is blocked, the pressurizing device is started, and mine water in the roadway is output into the sleeve in the water injection hole through the pressurizing device and the control device. By applying the method, mine water treatment procedures can be reduced, and the treatment cost is reduced.

Description

technical field [0001] The present application relates to the technical field of mining engineering, and in particular, to a method for treating mine water. Background technique [0002] Mine gushing refers to the water that seeps into the roadway from aquifers or surface runoff during underground mining. In order to ensure safe production and prevent mine water hazards, measures must be taken to treat mine water. In the prior art, due to the requirement of zero discharge of mine water in many places, the traditional treatment process of mine water is mainly centralized treatment by large sewage plants on the ground, so that it can meet the requirements of reuse water quality and then be recycled. However, the use of large sewage plants to treat mine water has disadvantages such as large capital investment, high operating costs for mine water upgrading, large floor space, and secondary pollution. [0003] In view of this, some research teams have proposed the mine water de...
