Mining Engineering

Mining engineering is an engineering discipline that applies science and technology to the extraction of minerals from the earth. Mining engineering is associated with many other disciplines, such as geology, mineral processing and metallurgy, geotechnical engineering and surveying. A mining engineer may manage any phase of mining operations – from exploration and discovery of the mineral resource, through feasibility study, mine design, development of plans, production and operations to mine closure.
With the process of Mineral extraction, some amount of waste and uneconomic material are generated which are the primary source of pollution in the vicinity of mines. Mining activities by their nature cause a disturbance of the natural environment in and around which the minerals are located. Mining engineers must therefore be concerned not only with the production and processing of mineral commodities, but also with the mitigation of damage to the environment both during and after mining as a result of the change in the mining area.

Landsat 8 Oli Processing

Subset of your image that only includes the areas our are interested in. This saves disk space and processing time. Some software packages refer to this process as subsetting while others use the term clipping. Most raster data can be subset using XY coordinates, vector files or user created Regions of Interest (ROI). This process always creates a new dataset that only contains your data subset.

Minimum noise fraction (MNF) transformation is used to show the variation between bands in an image. This is a statistical method which works out differences in an image based on pixel DNs in various bands. MNF determines the inherent dimensionality of image data, to segregate noise in the data, and to reduce the computational requirements for subsequent processing. This step is often completed as a precursor to other types of analysis. Basically it is a way of simplifying the data. The MNF transform is essentially two principal component transformations. The first transformation, based on an estimated noise covariance matrix, decorrelates and rescales the noise in the data. [2]

This first step results in transformed data in which the noise has unit variance and no band-to-band correlations. The second step is a standard principal components transformation which creates several new bands containing the majority of the information. By using only the coherent portions, the noise is separated from the data, thus improving spectral processing results. Once applying MNF technique, on the 7 bands images TM (After being calibrated in reflectance mode), we will have like result 7 new bands images MNF. The image pixels are presented by eigenvalues. In examining the eigenvalues it can be seen that the first MNF bands ( 1 and 2) have the highest values while the remaining bands have consistent low values. It is the first two bands with the large values that contain most of the information and it is these bands that correspond to MNF images. The remaining low value bands (3 and under for example) are seen as noise. The images show the information compressed into only a few bands. The redundancy of the data is eliminated and noise is also removed. The result are more interpretable images. You could say that the data has been simplified or the dimensionality has been reduced. 

Optimum Index Factor (OIF) is a statistic value that can be used to select the optimum combination of three bands in a satellite image with which you want to create a color composite. The optimum combination of bands out of all possible 3-band combinations is the one with the highest amount of 'information' (= highest sum of standard deviations), with the least amount of duplication (lowest correlation among band pairs). The limitation of the OIF calculation is that, the best combination for conveying the overall information in a large scene may not be the best combination for conveying the specific information desired by the image analysis. This from experience in most cases is reasonable and that also depends on the type of study. The aim of this study is to use OIF technique to rank all the possible three-band combinations with the best favorable for geological mapping of El-Beda Prospect. [3] Based on the results obtained from OIF, the combination 7, 2 and 1 shows the highest value of OIF with the first rank. This band combination has the most information with the least amount of duplication so that the boundaries between rock units and other geological features are very clear.

Landsat 8 Preprocessing

Pre-processing of Landsat-8 OLI/TIRS data stage consists of those operations that prepare data for subsequent analysis that attempts to correct or compensate for systematic errors. The digital images are subjected to several corrections such as radiometric and atmospheric. Landsat-8 data were converted to surface reflectance by top-of-atmosphere (TOA) method Using Envi, which is recommended for calibration in mineralogical mapping, as it does not require prior Knowledge of samples collected in the field. Thermal atmospheric correction was performed on TIR bands with a normalized pixel regression method [1]. The 90-m resolution TIR bands were re-sampled to correspond to 30-m spatial dimensions for some image processing applications. Nearest neighbor re-sampling Was used to preserve the original pixel values in the re-sampled images.

Radiometric correction is done to reduce or correct errors in the digital numbers of images. The process improves the interpretability and quality of remote sensed data. Radiometric calibration and correction are particularly important when comparing data sets over a multiple time periods. The energy that sensors onboard aircrafts or satellites record can differ from the actual energy emitted or reflected from a surface on the ground. This is due to the sun's azimuth and elevation and atmospheric conditions that can influence the observed energy. Therefore, in order to obtain the real ground irradiance or reflectance, radiometric errors must be corrected for. The value recorded for a given pixel includes not only the reflected or emitted radiation from the surface, but also the radiation scattered and emitted by the atmosphere. In most cases were are interested in the actual surface values. To achieve these values radiometric calibration and correction must be applied.

Calibrated A sensor records the intensity of the electromagnetic radiation for each pixel as a digital number (DN). These digital numbers can be converted to more meaningful real world units like radiance, reflectance or brightness temperature. Sensor specific information is needed to carry out this calibration. In the case of Landsat data, the metadata file contains this information. Most image processing software packages have radiometric calibration tools. In ENVI some Landsat data can be converted directly to reflectance, with out needing to first calculate radiance. The Radiometric calibration has been done by Envi.

Atmospheric correction is the process of removing the effects of the atmosphere to produce surface reflectance values. Atmospheric correction can significantly improve the interpretability and use of an image. Ideally this process requires knowledge of the atmospheric conditions and aerosol properties at the time the image was acquired. The data had been corrected by FLAASH Module in ENVI.

Format Sultra Demo PT. Vale dijakarta

Jakarta, Mining Engineering Blog - Forum Masyarakat Tambang Sulawesi Tenggara (FORMAT) Sultra dan beberapa elemen mahasiswa lainnya demo di tugu Patung Kuda serta Monas Jakarta. Mereka menuntut PT Vale Indonesia hengkang dari Sulawesi Tenggara.

Ketua tim monitoring dan kampanye FORMAT Sultra, Israfil melalui siaran persnya kepada wartawan menjelaskan, aksi diikuti Ikatan Mahasiswa Teknik Pertambangan Sultra (IMTPS), Pusat Studi Sosial Masyarakat dan Ikatan Mahasiswa Pemuda Sultra di Jakarta.

"Kami memang menolak keberadaan PT.Vale di Sultra karena dinilai melakukan pembodohan dan pembohongan kepada pemerintah dan masyarakat dengan janji janji membangun pabrik tapi sampai saat ini tidak pernah terwujud," teriak massa Format Sultra.

Menurut FORMAT, PT Inco yang sekarang sudah berubah jadi PT Vale Indonesia dan sudah menguasai lahan tambang di Sultra sejak 47 tahun silam tetapi hingga kini lahan tambang itu dibiarkan jadi lahan tidur tanpa diolah Vale selaku Pemegang Izin Pertambangan.

"Kami masyarakat dan pemerintah Sultra hanya dijanji janji terus tanpa ada wujudnya. Kami konsisten perjuangkan penolakan terhadap PT Vale dan berhenti melakukan segala aktivitas yang terus menerus membodohi rakyat Sultra," ujar Israfil.

Ditempat terpisah Ketua FORMAT Sultra, Faisal mengatakan akan tetap mengawal aksi penolakan ini hingga perusahaan itu mendirikan pabrik pemurnian nikel seperti di daerah Soroako Kabupaten Luwu Timur.
