Embodiment
When certain survey district carries out transient electromagnetic work, its ore body buried depth is about 1000m, composes and is stored in Carboniferous System HUANGLONG In group-group layer position, ship mountain, in like stratiform output, its occurrence is consistent with country rock with form.Ore body spread in the plane is wider, and Change less in the degree of depth.Ore body is mainly made up of cupric skarns, cupriferous pyrite, cupric serpentinite, copper-bearing pyrrhotite etc.. The direct country rock in ore body chassis is unite under the Carboniferous System mountain, Koryo group rock and quartz diorite, based on horn stone siltstone.Ore body Directly taking over a business rock is HUANGLONG group griotte, and top is the rocks such as Xi-Xia group griotte.Ore body simple structure, research degree is relatively High.Having preferable electrical property feature difference between ore body and country rock, ore body itself has good electric conductivity, and the main table of country rock It is now high resistant feature, is suitable for electromagnetic exploration.Early stage is through repeatedly exploring, it is thus achieved that ore body model (Fig. 5).
Country rock is according to being electrically divided into three layers, and ground floor resistivity is 1000 Ω m, and second layer resistivity is 500 Ω M, substrate resistance rate is 5000 Ω m.Ground floor ore body resistivity value is 100 Ω m, along between ground floor and second layer country rock Interface compose deposit, run through whole survey region；Second layer ore body is composed along the interface between the second layer and substrate and is deposited, and is mainly distributed In the range of 300m--1100m.Two-layer orebody thickness is each about 50m--100m, is about 600m--along its extension moving towards direction 800m.Ore body has certain fluctuating, and the vertical characteristics scope of ground floor ore body is about between 300m--1000m, second layer ore deposit Body is distributed between 800m--1000m.
According to described survey district copper mine ore body, carry out modelling and multiple tracks transient electromagnetic data forward modelling, then pressed The method that the embodiment of the present invention proposes carries out seismic wavefield data conversion and process.Fig. 6 is the degree of depth after seismic processing Migrated section, is analyzed according to figure it follows that (1) processing profiles has substantially reflected rising of electrical interface and two-layer ore body Volt form.Reflexive property and the phase property of reflection line-ups according to virtual seismic wave field are it is inferred that Article 1 and Article two, lineups correspond to the end face of ground floor ore body, bottom surface and first country rock aspect respectively, and Article 3 lineups correspond to The end face of second layer ore body；(2) the model average resistivity value used is relatively big, due to the high resistance medium filtering to radio-frequency component Acting on relatively weak, when the degree of depth is bigger, the radio-frequency component of wave field is still the abundantest, has higher resolution, for deeper Second layer ore body end face still have significantly reflection；(3) less due to the laterally continuity scope of second layer ore body, its end face corresponding The lineups amplitude in section both sides reduced.
Although disclosed embodiment is as above, but its content is only to facilitate understand the technical side of the present invention Case and the embodiment that uses, be not intended to limit the present invention.Technical staff in any the technical field of the invention, not On the premise of departing from disclosed core technology scheme, any amendment and change can be made in the form implemented and details Change, but the protection domain that the present invention is limited, still must limit in the range of standard with appending claims.
