Abstract
The utility model belongs to the technical field of in-situ leaching mine leaching mining wells and particularly discloses an in-situ leaching uranium mining process well. The in-situ leaching uranium mining process well comprises a PVC (polyvinyl chloride) casing which is arranged in am open well drilled hole and a cement sheath which is arranged between the hole wall of the open well drilled hole and the casing wall of the PVC casing, wherein an annulus is formed on the same horizontal position of the cement sheath and the PVC casing; the PVC casing is divided into two sections by the annulus; the upper section is a cylinder; the lower section is an inverted cone; the cement sheath is divided into two sections by the annulus; the position of the annulus corresponds to the position of an underground ore bed section. The PVC casing is adopted to from a main body of a wellhead, the cement sheath is arranged between the casing and the drilled hole, and a part of the casing and a part of the cement sheath are cut off to form an annulus structure; due to the adoption of the annulus design and a sealing structure which is designed above the annulus, useless surrounding rock is wholly sealed, so that an ore bed is an unique stratum which is communicated with the well, and infiltration liquid for mining or leaching agent only moves in a useful ore bed, which is most beneficial to infiltration mining.
Description
Technical field
The utility model soaks mine with belonging to and soaks and adopt well technical field, is specifically related to a kind of patterning method and builds the ground dipping uranium extracting process well of strainer.
Background technology
The uranium extracting process well of In-situ Leaching Uranium Mine application is at present complete in filling out gravel structure well, fill out gravel structure well constructs and fills out gravel, builds the core process such as sealing layer and easily complete in the depth bounds that is in the past less than 400 meters, but now along with mining depth exceedes 400 meters, filling out gravel structure well gravel and sealing layer throws not in place or does not throw, workmanship does not ensure, is difficult to reach designing requirement; There is large section of country rock to be connected with well, be unfavorable for that uranium ore soaks to adopt; Difficulty of construction increases, individual well claim for eot 1-2 days, productivity slowdown.Along with being less than the minimizing of shallow-layer uranium ore resource of 400 meters, open uranium mine mining depth future and will exceed 400 meters, explored mineral deposit reaches more than 800 meter the most deeply, at present, existing part uranium mine mining depth has exceeded 400 meters, fills out gravel structure well in the past and has been difficult to construction and has been not suitable for soaking and adopts.
Summary of the invention
The purpose of this utility model is to provide a kind of applicable uranium mine mining depth to exceed 400 meters of ground dipping uranium extracting process wells in situation.
The technical solution of the utility model is as follows:
A kind of ground dipping uranium extracting process well, it comprises the PVC sleeve pipe that is located in bore hole boring, is located at the cement sheath between described bore hole borehole wall and PVC sleeve pipe tube wall, described cement sheath and PVC sleeve pipe are processed with annular space in same level position, described annular space makes PVC sleeve pipe be divided into two sections, epimere is cylinder, hypomere is inverted circular cone, and described annular space makes cement sheath be divided into two sections; The position of the ore bed section under the position corresponding ground of above-mentioned annular space.
The lower end of the cylinder of described PVC sleeve pipe is provided with sealing device.
Described sealing device is sealing cup.
In the annular space position of the hypomere of described PVC sleeve pipe and circular cone, strainer is installed.
The beneficial effects of the utility model are: adopt PVC sleeve pipe to form well head main body, and on the cement sheath between sleeve pipe and sleeve pipe and boring, after cutting part sleeve pipe and cement sheath, form annular space structure, due to the design of annular space, and above annular space, design hermetically-sealed construction, useless country rock all can be shut, making ore bed is unique stratum being connected with well, leaching solution or the leachate of mining are only moved in useful ore bed, the most favourable to solution mining.Such structure design can adapt to the situation that uranium mine mining depth has exceeded 400 meters, and the ground-dipping uranium extraction well of this spline structure can be easily, fully construct by designing requirement.Simultaneously at annular space position design filter, make to adopt uranium well in drawing liquid process for stopping that the sand in ore bed enters in PVC sleeve pipe.

Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
As shown in Figure 1, dig bore hole boring 1 at below ground, at bore hole 1 interior the installations PVC sleeve pipe 3 of holing, described PVC sleeve pipe 3 and bore hole are holed and are left space between 1 hole wall, are full of cement, formation cement sheath 2 in space.Described PVC sleeve pipe 3 is divided into two sections, and epimere is cylinder, and hypomere is inverted circular cone, between cylinder and circular cone, leave certain distance, cement sheath 2 also leaves identical distance in position corresponding to annular space 4 places, therefore between two sections of cement sheath 2, and between cylinder and circular cone, forms annular space 4.
Underground ore bed section 7 see through cement sheath 2 distance and cylinder and circular cone between distance, by annular space 4, ore bed section 7 is communicated with PVC sleeve pipe 3.
The lower end of the cylinder of described PVC sleeve pipe 3 is provided with sealing device 6, useless around country rock all can be shut, and makes ore bed section 7 become a unique stratum being communicated with PVC sleeve pipe 3.Above-mentioned sealing device 6 can be sealing cup.
In the position of the annular space 4 of the hypomere of PVC sleeve pipe 3 and circular cone, strainer 5 is installed, filters for adopting uranium well the sand that flows to sleeve pipe 3 from ore bed 7 when the drawing liquid.
In the middle of the present embodiment, bore hole 1 diameter of holing is 270mm, and the diameter of annular space is 320mm.
The specification that PVC sleeve pipe 3 is selected is 152 × 126.4 × 12.8mm(external diameter × internal diameter × thickness), length is 8 meters.
Above-mentioned strainer 5 is the outer ring skeleton strainer of 114 × 66 millimeters of specifications (external diameter internal diameter).
