The basins in Xingmeng area are superimposed and craton type. The basins host many large uranium deposits. Here, we studied the geological characteristics, uranium mineralization ages, and C-O-S isotopes in the basins. In addition, we discussed the uranium mineralization stages, uranium mineralization fluids, and established the …Web
A method is presented to transfer geological uncertainty into mine planning. First, SGS is used to generate fifty realizations of an oil sands deposit. An optimum final pit limits design is ...Web
Mine planning is the process that determines the way in which an ore deposit will be mined over the life of a mining operation. It necessarily draws on everything that …Web
There are several factors that influence the selection of a mining method: Physical, mechanical and chemical characteristics of an ore-body and its host rock (compressive strength, weak planes, groundwater, mineralogy etc.); the value of mineral and grade; geometry of the deposit (thickness, size, shape and depth); labor (skilled and un-skilled ...Web
method of mining excavation according to mining-geological parameters, ie the rational selection of a group of favorable methods for the exploitation of a certain ore deposit. Ghazdali et al.Web
According to the geological characteristics, IP geophysical and soil geochemical anomalies, and audio-frequency geodesy results of the Nanpo gold deposit, the prospecting target area was determined, …Web
Selection of the most optimal method of mining in the stage of designing the mine is considered to be an important and sensitive issue as far as designing the system of exploitation of a mine is concerned. This selection is based on geological, geotechnical, geographical, economic, social and political studies, etc. recognizing all of the factors …Web
Lateritic gold deposits are gradually being taken seriously geological exploration workers as an important gold deposit type. Based on the results of previous studies, combined the field exploration work of Nawudong gold deposit in Laos and characteristics of typical lateritic gold at home and broad, this paper expound in detail …Web
Ore minerals are naturally occurring minerals that contain valuable elements or minerals in sufficient quantities to be economically mined and processed for their desired metal or mineral content. These minerals are typically extracted from the Earth's crust and processed to obtain the valuable elements or minerals for various industrial, …Web
MMS is primarily influenced by several factors, including ore deposit geometry (e.g., size, shape, and dip), subsurface properties (e.g., mineral composition, lithology, homogeneity, deformation, …Web
the classification is for industrial-scale mining, with only the exclusion of thin ore deposits where portable mining equipment is unavoidable due to space-limited environment; the secondary criteria should be disregarded, for example, when strike-line or dip-line mining is governed not by the mining method, but by the parameters of the …Web
Abstract. Mining method selection is the first and most important problem in mine design. In this selection some of the parameters such as geological and geotechnical properties, economic ...Web

Mining method selection is a process to determine the mining method according to the mining technology of ore deposits and factors such as safety, …Web
An ore deposit model is a conceptual and/or empirical standard, ideally a population of natural phenomena, embodying both the descriptive features of the deposit type, the larger ore-bearing environment, and an explanation of these features in terms of geological, and hence of chemical and physical, processes. Hodgson, 1987.Web
One of the most important aspects of mining is selecting a mining method. It determines the efficiency of the economy, technology, and the environment. As shown in Fig. 4.5, mining technique selection is seen as an issue with multiple decision-makers. In reality, some mines exclusively use one type of mining.Web
Thus, the proper extraction method must be selected based on factors such as geology (lithological conditions, groundwater, rock mechanics and the genesis of …Web
There are several factors that influence the selection of a mining method: Physical, mechanical and chemical characteristics of an ore-body and its host rock (compressive …Web
Table of Contents. Geology - Mineral Deposits, Formation, Exploration: As mentioned above, the distribution of commercially significant mineral deposits, the economic factors associated with their recovery, and the estimates of available reserves constitute the basic concerns of economic geologists. Because continued industrial development is ...Web
Mining of the extensive, steeply dipping ore deposit takes several decades. An open-pit mining method is more often used in the early years of such a mining enterprise (ME). The management of the enterprise is faced with the problem of changing the mining method as the depth of the quarry increases. Untimely solution of this issue …Web
The following integrated technologies have been brought forward in a targeted manner, respectively, the integrated technology of "porphyry ore deposit model + hyperspectral + PIMA + high-precision magnetic survey + IP" for porphyry copper deposits, the "metallogenic model + horizon + Transient Electromagnetics + Induced Polarization" …Web
Geological and technological changes. Since the changes in the ore characteristics with cumulative extraction depend primarily on the types of deposits of a metal and the volumes of known and accessible resources of each type, it is apparent that "scarce" metals with bi-modal distribution, such as copper, will face the common changes …Web
