Abstract
The utility model relates to a mining type transition electromagnetism appearance, include transmitter, receiver, amplifier, send the loop line, receive loop line, transmitter power, receiver power supply, the transmitter mainly is the bipolarity square wave electric current that turns into the electric energy of transmitter power through electronic switch and commutator certain frequency, the transmitter flows through the bipolarity square wave electric current of certain frequency and sends the loop line and send the electromagnetic wave to the underground, the inside circuit of transmitter mainly includes the triplex: the transmitting circuit board, gauge outfit circuit board, DCDC converting circuit board, the inside circuit of receiver includes industrial control computer mainboard, signal amplifier, data acquisition board, DCDC power strip, receives the loop line, the electromagnetic wave of receiver through receiving mineral ore under loop line, signal amplifier, the data acquisition board place of receipt, metal and reflecting out. The utility model is suitable for a look for the low resistance ore body, have the advantage that the interference killing feature is strong, stability is good, resolution ratio is high.
Description
Technical field
The utility model belongs to a kind of geology detecting instrument, particularly a kind of Transient Electromagnetic Apparatus detecting deep layer mineral resources.
Background technology
Transient electromagnetic method is owing to having the incomparable advantage of many Traditional DC electrical methods, be the electromagnetic exploration method of new generation being developed rapidly popularization now, its range of application relates to the every field such as ore deposit, ground, oil, water conservancy, electric power, railway, traffic, coloured and defence engineering.But due to the Transient Electromagnetic Apparatus fetch long price of external production and sales, emissive power is little, solve deep prospecting and must adopt large transmitter loop working method, production efficiency is low, and large transmitter loop is difficult to the impact of factors such as carrying out the work under MODEL OVER COMPLEX TOPOGRAPHY, domestic applying is restricted.Calendar year 2001, we successfully have developed lightweight big current and launch positive and negative square wave transient electromagnetic instrument system.Domestic scholars is also powered for the feasibility of deep level transient electromagnetic prospecting from proof small transmitter loop big current theory and practice simultaneously, and this promotes for transient electromagnetic method and reconnoitres for geology of deep part the condition of creating.
Utility model content
The purpose of this utility model is to solve the problem, and proposes a kind of mining type Transient Electromagnetic Apparatus, and this mining type Transient Electromagnetic Apparatus has that antijamming capability is strong, good stability, resolution are high, Portable durable, feature simple to operate.
The purpose of this utility model is achieved through the following technical solutions: mining type Transient Electromagnetic Apparatus, is characterized in that: comprise transmitter, receiver, amplifier, transmission loop line, receive loop line, transmitter power, receiver power supply; The electric energy conversion of transmitter power is mainly the bipolarity square wave current of certain frequency by electronic switch and commutator by described transmitter, the bipolarity square wave current of certain frequency flows through and sends it back alignment underground transmission electromagnetic wave by described transmitter, the main circuit of described transmitter inside will comprise three parts: radiating circuit plate, gauge head circuit plate, DC/DC converter circuit plate; The circuit of described receiver inside comprises industrial control computer mainboard, signal amplifier, data acquisition board, DCDC power panel, receives loop line, and described receiver is by receiving loop line, signal amplifier, data acquisition board reception underground mineral ore, metallic reflection electromagnetic wave out.
The utility model advantage: 1. observe pure secondary field after power-off, do not disturb by primary field, the ability that notes abnormalities is strong; 2. do not shield by resistive formation, can overcome the tectal impact of low-resistance, penetration capacity is strong, and investigation depth is large, and general hundreds of rice, can reach more than 1 kilometer the most deeply; 3. little by the influence of topography, the spurious anomaly of topographic relief impact can not be produced in high resistant country rock area; In low-resistance country rock area, owing to being multiple tracks observation, the topographic relief impact in early stage road is also more easily differentiated; 4. high to the resolution of low resistivity zone, the relative position that the detection of a target buries can be shown clear, intuitively; 5. equipment flexible form is various, and profile survey and depth measurement work complete simultaneously, and work efficiency is high, contains much information, and can reduce multi-solution; 6. instrument is light, power large, and the area of power supply difficulty can normally work.
