Abstract Contamination of mercury (Hg) in ex-gold mining soil is the impetus for the development of amelioration technology that utilizes Indonesian sub-bituminous coal to study the soil surface charge and the chemical properties of ex-gold mining soil. This research was aimed to study surface charge and chemical properties of ex-gold mining soil ameliorated with Indonesian sub-bituminous coal. The experimental design used in this study was a Completely Randomized Design with three replications. The treatment was implemented in a pot with the equivalent dose: A = 0 (0.0g); B = 10 (0.5g); C = 2

Abstract:

Differential synthetic aperture radar interferometry (InSAR) is widely used to monitor ground surface deformation due to its wide coverage and high accuracy. However, the large-scale and rapid deformation that occurs in mining areas often leads to densely spaced interference fringes, thus, severely limiting the applicability of D-InSAR in mining subsidence monitoring. Sub-band InSAR can reduce phase gradients in interferograms by increasing the simulated wavelength, thereby characterising large-scale surface deformations. Nonetheless, accurate registration between non-overlapping sub-band imag

Abstract:

The accurate prediction of mining area surface deformation is essential to preventing large-scale coal mining-related surface collapse and ensure safety and daily life continuity. Monitoring subsidence in mining areas is challenged by environmental interference, causing data noise. This paper employs the Sparrow Search Algorithm, which integrates Sine Cosine and Cauchy mutation (SCSSA), to optimize variational mode decomposition (VMD) and combine multi-models for prediction. Firstly, SCSSA is employed to adaptively determine the parameters of VMD using envelope entropy as the fitness value. Su

Abstract:

Abstract Mountaintop removal mining is a large-scale surface mining technique that removes entire floral and faunal communities, along with soil horizons located above coal seams. In West Virginia, the majority of this mining occurs on forested mountaintops. However, after mining ceases the land is typically reclaimed to grasslands and shrublands, resulting in novel ecosystems. In this study, we examined responses of herpetofauna to these novel ecosystems 10–28 y postreclamation.

Abstract:

As an important parameter to characterize physical and biogeochemical processes, sea surface salinity (SSS) has received extensive attention. Cubist is a data mining model, which can be well-suited to estimate and analyze SSS in the Gulf of Mexico (GOM) because it can reflect the SSS internal heterogeneity in the GOM—overall circular distribution, and the seasonality related to temperature and river discharge changes. Using remote sensing reflectance (Rrs) at 412, 443, 488 (490), 555, and 667 (670) nm and sea surface temperature (SST), a cubist model was developed to estimate SSS with high acc

Abstract:

Despite advances in rockburst studies, suddenness of major geodynamic events is reported in a number of cases. Phenomenological tectonophysical model is suggested to explain some geodynamics phenomena. Prof. Petukhov I.M. suggested a concept: the Earth crust's critical stress condition is developed due to horizontal compressive forces and entrains rock strata from the sub-surface to a certain depth. The conditions that induced earthquake in 2013 at Bachat coal field in south west Kuzbass are considered in terms of critical stress developed in the top layer of the Earth crust. Estimates show th

The geotechnical characterization of the subsurface is a key requirement for most soil investigations, incl. those for reclaiming landfills and waste dumps associated with mining operations. New sensor technology, combined with intelligent analysis algorithms, allow for a faster and less expensive acquisition of the necessary information without loss of data quality. The use of advanced technologies to support and back up common site investigation techniques, such as cone penetration testing (CPT), can enhance the underground characterization process.

Abstract:

Extraction of underground minerals causes subsidence of the ground surface due to gravitational forces. The subsidence rate depends on the type of extracted ore, as well as its shape, thickness, and depth. Additionally, the embedding and overburden rock properties influence the time needed for the deformations to reach the surface. Using the results of geodetic deformation monitoring, which supply the information on pattern and magnitude of surface deformation, the performance of the mine may be evaluated. The monitoring can supply information on the actual rock mass behaviour during the opera

Abstract The primary objective of the present paper is an attempt at evaluating the influence of sub-level caving operations on the slope stability of a still-functioning open pit coal mine in Vietnam. Initially, various methods of predicting the impact of underground mining on surface stability are discussed. Those theoretical considerations were later utilized in the process of constructing a Flac-2D-software-based numerical model for calculating the influence of underground operation on the deformation and possible loss of stability of an open pit slope.

It was found in lava routes or large rivers in the Pasirian sub-district at Lumajang district. The location of sand material was in a river that passes through the regency road. This result was in many road damage in the district area. The efforts to overcome the damage that often occurs on roads in Pasirian sub-district included road improvement activities supported by road surface surveys using the RCI method which has been used in reporting basic road condition

Anthropogenic modifications influence river landscapes on multiple scales, which impact river-flow regimes and thus the production of river ESs.

Water pollution within mountainous watersheds is recognized as one of the foremost environmental challenges of our era. Extensive research has confirmed that major causes of this pollution are various human activities in natural areas, such as urban expansion, mining operations, and changes in land use. Similar humaninduced impacts can be seen in the Coruh River Basin (CRB) as a result of the building of large dams and roads, mining operations, and urban growth.

Abstract The East Coast Bauxite (ECB) Province of India, extending into the neighbouring States of Andhra Pradesh and Orissa, has contributed to a substantial rise in the total bauxite resource of the Indian sub-continent. Bauxite is gibbsitic and in situ. Thickness of the bauxite profiles varies from 3 to 54 m and bauxite is confined to select geomorphic expressions viz., sloping, landforms, and are amenable to open cast mechanised mining. There are chances of accelerated recharge of the groundwater table, through coursed run-off, of the meteoric precipitation in the mining areas. In fact, ti
