The method of the underground original place of nonmetallic mineral boring corrosion mining new technology; Different with traditional production technique; Reduce links such as traditional mining process digging, utilized novel directed drilling technology and fracturing technique simultaneously, can exploit the mineral reserve that hundreds of rice is difficult to exploit to thousands of rice; To the ocean underground mine, utilize offshore drilling platform also can implement the application of the underground original place of nonmetallic mineral boring corrosion mining simultaneously.
Summary of the invention
For overcoming the deficiency of prior art, the present invention provides the method for the underground original place of a kind of nonmetallic mineral boring corrosion mining new technology, especially is positioned at the liquid exploitation method of underground hundreds of rice to the thousands of meters mineral reserve that are difficult to exploit.This method comprises:
1, according to the exploration result, formulates recovery scheme;
2, select ore body of certain scale according to the structure situation, delimit the mining block;
3, in delimiting block, carry out directed drilling;
4, require the target stratum at drilling depth, with high strength well cementing material well cementation back completion;
5,, formulate offtake pattern distribution scheme and drilling design scheme according to ore body mineralogical composition cubage ore body mineral deposits.
Above-mentioned well pattern distribution scheme can adopt the well pattern distribution mode that is arranged in parallel, and injects liquid measure and extraction liquid measure and keeps quite level;
Above-mentioned all injection wells and extraction well utilize directional well connection or fracturing technique that formation at target locations is transformed.
In inner passage or the crack of forming of ore body,, promptly inject well in the plane and the extraction well all forms connected state to form circulation corrosion passage or the seepage flow corrosion passage between the flooding pattern.
The nonmetal mineral reserve that underground original place boring corrosion mining new technology utilizes novel directed drilling technology and fracturing technique exploitation hundreds of rice to be difficult to exploit to thousands of rice; Utilize water or chemolysis liquid etc.; By chemical reaction and physical reactions; Corrosion goes out the valuable mineral composition in the ore body, has changed on traditional production technique large-scale infrastructure construction, has reduced in the mining process links such as digging.Concrete advantage is following:
1, the mining of this patented technology liquid all not be used in underground or large-scale infrastructure is carried out on ground.
2, the nonmetal mineral reserve that can dark to burying (hundreds of rice-thousands of rice) are difficult to exploit carry out novel directed liquid mining.
3, reduced link such as digging in traditional mining process.
4, carry out the down-hole unmanned operation.
5, the present invention is water or chemolysis liquid through the lysate that the target ore body is used, and implements can not pollute environment after effective environmental practice.
6, technical matters flow process of the present invention can not cause the dust that forms in surface production like traditional handicraft, the environment pollution that toxic and harmful produces all in underground completion.
