  Insights in Mining Science & Technology Abstract The history of science has accumulated many hypotheses and theories about the development of the Earth. The dominant part of them uses the reduction principle (reducing the complex to the simple and the higher to the lower), ignoring the effect of emergence. The end of the twentieth century coincided with the awareness of the physical limitations of Euclidean space, the beginning of a new rationality, a serious transformation of science from a discrete-atomic (traditional) Platonic to a holistic resonant-field Aristotle, where the form of systems is of fundamental importance. In search of a new paradigm, we turned to elliptical notions of space; as a result, we created a holographic model of matter (GMP). The article contains the rationale for the resonant field theory of global tectonics of planets and the geodynamics of the Earth based on the ideas of modern rationality, including the principle of wave-particle d...

  Insights in Mining Science & Technology Abstract The aim of this study is to develop a methodology that can contribute to the construction of scenarios for mine planning and to evaluation of the impact of geological uncertainties provided by simulated models. The approach suggested here includes the definition of a methodology to control and incorporate the local uncertainties associated with the ore in order to improve mine planning, assess the sensitivity of financial return and while considering the variations and uncertainty related to the geological model and grade estimation. Keywords: Mine planning; Geological uncertainty; Geostatistical simulation; Risk analysis Introduction From exploration to mine planning, methodologies for quantifying the risk associated with mineral deposits can dramatically improve the decision-making process in the mining industry. Small variations in boundary conditions can have a significant impact on t...

  Insights in Mining Science & Technology Introduction Indonesia has long adapted the contracting scenario for petroleum cooperation contracts involving international oil and gas companies as the second party to participate in oil and gas production through production sharing contract (PSC) scenario since it was first introduced in 1966. PSC is very popular amidst countries with less reservoirs and is adapted in Ecuador, Equatorial Guinea, India, Algeria, and other countries [1]. In this scenario, gross revenue made once oilfield is put into production is preliminarily cut by 20 % for First Tranche Petroleum (FTP) furthermore subtracted by the operational cost. The remaining balance is referred as equity to be split (ETS) which then will be divided between the oil and gas company and the host government by the ratio stipulated in the contract [2]. Indonesia applied 70-30 and 85-15 ratio (state-to-contractor) for revenue resulted from gas and oil production, respectively. All pr...
