   As a new mode of mining development, green mine optimizes the development and utilization of mineral resources with a minimum of the environmental impact, and how to objectively evaluate the construction level of the green mine has become the key to promote green mine construction and it has also been an important path to achieve sustainable development of mineral resources. The evaluation system and methods of green mine construction, however, are not perfect at present as the existing green mine evaluation mostly adopts the index scoring accumulation method, with which the internal relations between the indicators are ignored, and the subjective influence it causes is too large. Based on the framework model of driving forces, pressure, state, impact and response, an indicator system is constructed in this paper to express the internal relationship between indicators more intuitively. Combined with subjective and objective combination weighting method to determine the index weight, TOPSIS and coupling coordination degree models are introduced to quantitatively evaluate the spatio-temporal evolution process of green mine construction and the coupling coordination between subsystems, analyze and obtain the main obstacle factors affecting the green mine construction of enterprises, and provide suggestions and countermeasures for the improvement of green mine construction of enterprises. The applicability of the model is verified by an actual case study of a mine in China. The model enriches the connotation of green mines, making the evaluation process and results fairer and more reliable, thus providing an effective way to promote the sustainable development of mines.

   The use of geostatistics in ore evaluation studies is based on the relationship between point values and their spatial distribution. When an orebody is deformed the syn-depositional spatial relationship between control points is altered and it is extremely difficult to represent these points on a single plan suitable for ore reserve estimation. To overcome this problem, deformed orebodies could be dissected into a number of individual units and analysed separately, but this results in a reduction of control points available for analysis. An alternative to orebody dissection is to unroll the deposit so as to return control points back as close as possible to their original relative spatial locations. This paper describes attempts to reconstruct the Nygruvan orebody structurally at Knalla mine, Zinkgruvan, Sweden, which is operated by Vieille-Montagne Sverige. The deposit is located in the Bergslagen geological province of south-central Sweden, and has features in common with stratiform volcanogenic massive Zn-Pb sulphides and sediment hosted exhalative Zn-Pb deposits. Nygruvan is essentially a thin (5–20 m) tabular deposit of large lateral extent, dipping at 60–80° to the northeast, which was folded and faulted during the Svecofennian orogeny. Current ore resource evaluation methods employ the polygon method for global resources using diamond drill information, and the extrapolation of chip sample data between mine levels to produce reserves of mining blocks. These methods do not take account of orebody structure, assuming it to be a planar structure of variable thickness. Structural reconstructions of thrust belts and deformed basins are usually achieved by drawing sections in the plane containing the movement vector. Sectional reconstruction methods do not, however, give consideration to transverse movements. If strain is triaxial, a two dimensional restoration using cross sections is not appropriate, instead a three dimensional method should be used. To date little work has been done on the development of a suitable method applicable to deformed orebodies A small area of the mine has been selected for preliminary studies and a variety of manual methods applied in order to develop a suitable computerized restoration algorithm (these include two dimensional sectional and triaxial methods). A new Datamine unrolling package, which will be tested on this deposit, is described. A geostatistical study will be undertaken to generate a block reserve model once the deposit has been unrolled satisfactorily. Read less

   In the context of globalization in the mining industry, assessing the production feasibility of mining projects by smart technology is crucial for the improvement of mining development efficiency. However, evaluating the feasibility of such projects faces significant challenges due to incomplete data and complex variables. In recent years, the development of big data technology has offered new possibilities for rapidly evaluating mining projects. This study conducts an intelligent evaluation of gold mines based on global mineral resources data to estimate whether a gold mine project can be put into production. A technical workflow is constructed, including data filling, evaluation model construction, and production feasibility evaluation. Based on the workflow, the missing data is filled in by the Miceforest imputation algorithm first. The evaluation model is established based on the Random Forest model to quantitatively predict the feasibility of the mining project being put into production, and important features of the model are extracted using Shapley Additive explanation(SHAP). This workflow may enhance the efficiency and accuracy of quantitative production feasibility evaluation for mining projects, with an accuracy rate increased from 93.80% to 95.99%. Results suggest that the features of estimated mine life and gold ore grade have the most significant impact on production feasibility. Read less
