The development of mine digitization information system and its application to the Lanping Pb-Zn mine

Abstract

To compile the software package of the mine digitization information system in terms of the principle and methods of mathematics geology and geographic information system using computer languages such as VB and Matlab, this paper introduces the function composition and operating environment of this information system, and illustrates the function and effectiveness of the software package as exemplified by the Lanping Pb-Zn mine, Yunnan Province.

Mathematic-Economical Model of KT5 Orebody in Yangla Copper Deposit

“…After the variation function is established, examination should be followed. As viewed from the results of examination, the error involved in the estimated value of Gu grade from the actual value is relatively samall, the variance is also very small and the correlation coefficient is relatively hihg.It has been proved that the selected model parameters are correct, and the estimated values are most superior on the whole,with no deviation [4]. Grade modeling.…”

“…Establishment of the mathematical model of ore deposits involves the calculation of experimental function of variation and the fitting and check of theoretical function of variation. It is also one of the technological keys to this kind of research [4]. The purpose of calculating the experimental variation function is to obtain the theory variation function, which is the foundation to conduct ore grade evaluation.…”

“…Grade modeling is to evaluate the grade of each unit block within the modeling range according to its peripherals geological information. After the estimation of parameter is confirmed, the grade can be automatically evaluated in accordance with the available geological information with the software system [4]. The next figure(Fig.…”

“…After the variation function is established, examination should be followed. As viewed from the results of examination, the error involved in the estimated value of Pb grade from the actual value is relatively samall, the variance is also very small and the correlation coefficient is relatively hihg.It has been proved that the selected model parameters are correct, and the estimated values are most superior on the whole,with no deviation [5]. Grade modeling.…”

“…Grade modeling is to evaluate the grade of each unit block within the modeling range according to its peripherals geological information. After the estimation of parameter is confirmed, the grade can be automatically evaluated in accordance with the available geological information with the software system [5].After grade evaluation is finished, the sectional maps in the arbitrary position and the planar maps at the arbitrary level can be drawn in terms of different boundary grades, or the distribution loci and shapes of poor and rich orebodies can be distinguished in accordance with different grade colors.
