Small-scale mining usually operates under high geological uncertainty conditions. This turns mine planning into a complex and sometimes inaccurate task, resulting in low productivity and substantial variability in the quantity and quality of the mineral products. This research demonstrates how the application of a novel methodology that relies on traditional and low-cost geophysical methods can contribute to mine planning in small-scale mining. A combination of resistivity and induced polarization methods is applied to enhance mine planning decision-making in three small-scale mining operations. This approach allows for the acquisition of new data regarding local geological settings, supporting geological modelling and enhancing decision-making processes for mine planning in a timely and low-cost fashion. The results indicate time savings of up to 77% and cost reductions of up to 94% as compared with conventional methods, contributing to more effective mine planning and, ultimately, improving sustainability in small-scale mining.

“…Hence, we first conducted a basic data collection and field survey. To obtain a more accurate distribution of the goafs, geophysical exploration, including application of the EH4 magnetotelluric method and high-density resistivity method, and drilling were performed [19]. When interpreting geophysical data, we should make repeated comparisons with the drilling results and geophysical characteristics to perform a comprehensive analysis to determine the distribution of the goafs more precisely and accurately.…”

A large area of room mining goaf has been left throughout the history of coal mining worldwide. However, because the pillars cannot perpetually retain stability, the sudden collapse of a large area of goaf can occur. The existing large areas of room mining goaf have become a potential source of geological risks in mining areas with room mining goafs worldwide. To elucidate the distribution and state of the goafs, a survey of the characteristics of goafs was carried out by geophysical exploration and drilling methods. From this complete survey of room mining goafs, this paper has outlined eight common goaf risks, emphasizing the types of goaf risks that require precautions, and the formation mechanisms of each goaf risk has been analyzed. Considering that the occurrence of a risk may lead to several other risks and there is a certain interaction between the risks, more specific room mining goaf risk forms, causes and scopes of influence have been listed. It is advantageous to use a support vector machine, which is useful for small-sample problems, to assess the goafs. A support vector machine assessment model of room mining goafs was established, and sample training and verification were carried out. Comparing the risk assessment results with those of the field investigation, it can be seen that the evaluation model has a high accuracy. This work can greatly contribute to the prediction and prevention of risks induced by room mining goaf.

“…These investigations have sought to acquire information on the location of subsurface sinkhole cavities [3], characterize the subsurface karst environment [4], and visualize dissolution zones within karst systems to determine the risk of surface collapse [5]. Other studies have highlighted the significant difference in resistivity between watersaturated karst and karst bedrock [6], sinkhole formation due to the widening of vertical dissolution at the intersection of three series of conduit channels [7], and the geological characteristics of cavities and other features in highly heterogeneous karst environments [8]. Meanwhile, the study [9] mapped voids and caves between carbonate units, cavityfilling sediments, and groundwater.…”

offers significant tourism and fisheries potential, supported by the nearby Sempu Island Nature Reserve and a Fish Auction Site (FAS). However, the coastal region is prone to karstification, which may be exacerbated by recent land use developments in the surrounding area. This study aims to analyze the rock layer structures and assess the vulnerability of karst land use to the ongoing karstification process. Electrical Resistivity Tomography (ERT) and Magnetotelluric (MT) methods were employed to investigate karst land within the study area. The findings revealed the presence of karst aquifers in Zone A, extending to a depth of 250 m, characterized by low resistivity values. In Zone B, karst limestone deformation was observed at several locations due to karstification, with moderate resistivity values detected at a depth of 300 m on the surface, indicating vulnerability to karst disasters. High resistivity values dominated areas with massive karst limestone, ranging from the surface to a depth of 400 m. Furthermore, it was found that a significant portion of karst land is utilized for settlements, plantations, and rice paddies, potentially disrupting the karst ecosystem due to household, plantation, and agricultural waste. This study highlights the importance of understanding the impact of land use on karst vulnerability and informs mitigation strategies for sustainable development in the Sendang Biru region.
