Estimasi Distribusi Mineral Emas dari Data IP

Ekplorasi mineral khususnya mineral emas atau logam mulia dibutuhkan bertahun-tahun untuk tahapanya, diantara tahapan eksplorasi mineral logam mulia dimulai dari kajian pendahuluan yang didalamnya ada pemetaan geologi regional, topografi,struktur geologi, uji lab dan lainya. selain melakukan eksplorasi pendahuluan juga dilakukan eksplorasi lanjutan dengan berbagai tahapan diantaranya pemetaan geologi  detail, eksplrasi geofisika, dan pengeboran.

Dalam Eksplorasi geofisika, metode yang banyak digunakan untuk eksplorasi mineral terutama logam adalah Metode Resistivity-IP atau yang banyak dikenal adalah Geolistrik(Metode yang menggunakan sumber dari listrik  seperti aki, jenset dan lainya yang bisa di bawa-bawa).

Metode resistivity-IP sudah banyak diterapkan pada alat-alat yang menggunakan sumber kelistrikan seperti Zonge, Iris, Supersting, Ares dan lainya, sedangkan beberapa merk seperti Naniura masih menggunakan hanya data resistivitasnya saja sehingga untuk survey mineral dan struktur komplek agak sulit. Penggunaan alat-alat tersebut akan berpengaruh pada hasil akhir pengambilan data dan kstabilan datanya sehingga ketika dilakukan pengolahan data lanjut seperti inversi dan pemodelan mineral akan berpengaruh juga.

Pemodelan data resistivity-IP dimaksudkan untuk mempermudah proses pengeboran dan estimasi sebaran baik lateral maupun vertikal sehingga perencanaan penambangan dan lainya lebih efektif, baik itu biaya dan waktunya. Pemodelan data resistivity-IP untuk inversi banyak menggunakan software Earth Imager yang dikeluarkan oleh pabrikan Supersting atau res2Dinv yang dikeluarkan oleh Geotomo. Hasil dari keduanya atau dengan software lain relatif sama untuk kondisi yang tidak terlalu sulit tetapi untuk daerah dengan struktur dan mineral yang komplek akan tergantung pada pemilihan parameter baik pada saat pengambilan data dan juga pengolahan datanya.

Contoh di bawah ini adalah pemodelan mineral akhir dari sebaran mineral emas menggunakan software oasis montaj dengan menggunakan inputan data dari inversi res2Dinv. Pemodelan ini sangat bergantung pada kualitas data pengukuran dilapangan sehingga tidak ada lagi koreksi dan editing pada saat pengolahan data sehingga tugas untuk pengolahan data dan pemodelan tidak sesualit ketika data lapangan tidak dikontrol dengan baik.

Spesifikasi Supersting R8

Item Description
Measurement Modes Apparent resistivity, resistance, induced polarization (IP), SP, and battery voltage.
Measurement Range +/- 10Vp-p.
Measuring Resolution Max 30 nV—depends on voltage level.
Screen Resolution 4 digits in engineering notation.
Transmitter 200W internal transmitter. 5kW, 10kW and 15kW external transmitters also available (see separate brochure).
Output Current 1 – 2000 mA continuous, measured to high accuracy.
Output Voltage 800 Vp-p—actual electrode voltage depends on transmitted current and ground resistivity.
Input Channels Five models available—8-, 6-, 4-, 2-, or 1-channel.
Input Gain Ranging Automatic—always uses full dynamic range of receiver.
Input Impedance >150 MOhm.
SP Compensation Automatic cancellation of SP voltages during resistivity measurement. Constant and linearly varying SP cancels completely (V/I and IP measurements).
Type Of IP Measurement Time domain chargeability (M). Six time slots measured and stored in memory.
IP Current Transmission ON+, OFF, ON-, OFF.
IP Cycle Times 0.5, 1, 2, 4, and 8 s.
Measure Cycles Running average of measurement displayed after each cycle. Automatic cycle stops when reading errors fall below user set limit or user set max cycles are done.
Resistivity Cycle Times Basic measure time is 0.2, 0.4, 0.8, 1.2, 3.6, 7.2, or 14.4 s as selected by user via keyboard. Autoranging and commutation adds about 1.4 s.
Signal Processing Continuous averaging after each complete cycle. Noise errors calculated and displayed as percentage of reading. Reading displayed as resistance (dV/I) and apparent resistivity (ohmm or ohmft). Resistivity is calculated using user-entered electrode distances.
Noise Suppression
  • Better than 100 dB at f >20 Hz.
  • Better than 120 dB at power line frequencies (16 2/3, 20, 50, and 60 Hz) for measurement cycles of 1.2 s and above.
Total Accuracy Better than 1% of reading in most cases (lab measurements). Field measurement accuracy depends on ground noise and resistivity.

Instrument will calculate and display running estimate of measuring accuracy.

System Calibration Calibration is done digitally by the microprocessor based on correction values stored in memory.
Supported Configurations
  • In manual mode: Resistance, Schlumberger, Wenner, dipole-dipole, pole-dipole, and pole-pole.
  • In automatic mode: Any configuration can be programmed via command file.
Operating System Stored in reprogrammable flash memory. Updated versions can be downloaded from our website and stored in the flash memory.
Data Storage Full resolution reading average and error are stored along with user-entered coordinates and time of day for each measurement. Storage is effected automatically in a job-oriented file system.
Data Display Apparent resistivity (ohmmeter), current intensity (mA), and measured voltage (mV) are displayed and stored in memory for each measurement.

Data can also be displayed on an Android device in real time as bright color pseudosections, IP curves, transmitter/receiver plot, contact resistance measurements, and more.

Memory Capacity Virtually unlimited data storage in real time on controlling Android device.

The internal SuperSting memory can store more than 79,000 measurements (resistivity mode) and more than 26,000 measurements in combined resistivity/IP mode.

Data Transmission Data can be instantaneously transferred from the Android device by email or by file transfer from the Android device USB port.

 

RS-232C channel available to dump data from instrument to a Windows-type computer on user command.

Automatic Multi-Electrodes The SuperSting is designed to run dipole-dipole, pole-dipole, pole-pole, gradient, Wenner, and Schlumberger surveys including roll-along surveys completely automatic with the patented Dual Mode Automatic Multi-Electrode system (U.S. Patent 6,404,203) or a passive electrode cable system.

 

The SuperSting can run any other array by using user-programmed command files. These are ASCII files that can be created using a regular text editor. The command files are uploaded to the SuperSting RAM memory and can at any time be recalled and run as a survey.
