This study explores the comprehensive approach of utilizing physiographical and geophysical electrical resistivity tomography (ERT) investigation to evaluate and address the challenges associated with abandoned, unplanned water-Blled galleries in Chasnala Colliery, located in Jharkhand, India. The integrated methodologies facilitate a thorough exam...

The Jharia coalfield stands as a paramount asset within the Indian economy. However, many pressing issues, such as coal fires, land subsidence, unplanned mining, child labor, deforestation, and air pollution, demand immediate attention. Effective planning and comprehensive mitigation strategies are imperative to address these challenges. This resea...

Underground galleries possess random subsidence threats if they are not treated well. Threats even become multifold when these galleries are located somewhere in the vicinity of the railway tracks. So, checking the stable ground formation or the health of the subsurface formation near railway tracks and mapping the galleries are very important task...

The first coal mining in India was started in the seventeenth century with an unplanned way in Raniganj coalfield, the coal capital of India. The coalfield was possessed by several small private companies which were nationalized in 1973. A part plan of Chanch/Victoria Area, Victoria West Colliery, BCCL, Raniganj Coalfield, India, indicates an under...

The objective of this communication is to establish a new technique for GPR data interpretation using continuous wavelet transform (CWT) approach. In the present study, we have adapted the CWT technique to detect the edges or abrupt changes in the signal. For validation of the proposed technique, we have acquired data over a known tunnel in point m...

The Palaeo- to Meso-Proterozoic (1.0–2.4 Ga) North Singhbhum Mobile Belt (NSMB) is an assembly of multiphase folded, low- to medium-grade meta-sedimentary and meta-igneous rocks, lying within the north Singhbhum crustal province. The mobile belt is situated between the Archean Singhbhum craton in the south and the Meso/Neo-Proterozoic (0.9–1.7 Ga)...

Old mine workings, mainly hidden galleries, goafs, shafts etc may pose a great threat to the local environment and also for future mine development. The present study mainly deals with delineation and mapping of old mine workings over Tikmani-Gareriya section, a part of east Basuria colliery, Jharia coal field, India using state-of-the-art 64 elect...

: Dragline bench blasting in Dudhichua and Nigahi projects of Northern Coalfields Limited (NCL) is a major activity contributing 13 MT and 15.52 MT of coal per annum respectively. This production is realized through blasting in overburden rocks with multiple rows (8-10 nos.) and holes per row (18-20 nos.) for obtaining a dragline cut measuring, typ...

The present study deals with groundwater prospecting in hardrock terrain. Initially, the Wenner–Schlumberger array and the dipole–dipole array data have been acquired using Syscal Junior Switch-48. Furthermore, data acquired using both arrays have been merged using Prosys-II data handling software for the inversion of the cumulative data for possib...

We present the seismic site characterization study using joint modelling of Horizontal-to-Vertical Spectral-Ratio (HVSR) and Rayleigh wave-phase velocity-dispersion curves obtained from Multi-channel Simulation with One Receiver (MSOR) in a part of Dhanbad, Jharkhand, India. The joint analysis of these two different but complementary datasets puts...

This paper deals with severe issue of groundwater crisis over a part of hard rock terrain in the premises of Central Institute of Mining and Fuel Research (CIMFR), Dhanbad, Jharkhand, India. The goal of this study is delineation and mapping of fractured rock mass for groundwater exploration. Generally, fractured rock formation is the only source of...

seismic site characterization and site response using microtremor data and dispersion curves.

We perform site characterization study by integrating the dissimilar but complementary datasets in the two step procedure of sequential inversion where Horizontal-to-Vertical Spectral Ratio (HVSR) and Rayleigh wave phase velocity dispersion curves are modelled to estimate the shear wave velocity profiles in a part of Dhanbad, Jharkhand, India. Thes...

The present study deals with the delineation of lineaments over Sir Creek offshore and its surroundings from EGM2008 gravity data using various derivative techniques owing to their costeffectiveness in prospective hydrocarbon exploration. Initially, 2-D and 3-D synthetic models have been generated with vertical prismatic objects at different depths...
