Surface miner was introduced for coal extraction at Lakhanpur open cast project of Mahanadi Coalfields Limited in 1999 for the first time and owing to its success and benefits it offered like elimination of drilling and blasting, smooth and stable high wall, selective mining for quality control and uniform output fragment size (-100mm) etc. it was adopted in many open cast coal mines and now has become a disruptive mass production technology for coal mining in India. In terms of coal resources in the country, Odisha stands first with 88.104 BT resources but the coal seams in Odisha are characterized by its high ash content and interlaced dirt bands (10 cm to 1.5 m) often termed as rejects. For maintaining coal quality, these dirt bands predominantly of sandstone and shale are also cut by surface miners and are segregated at the time of loading and transported to reject dumps or overburden dumps. These dirt bands have a significant impact on the performance of surface miners and must be taken into account during their selection. The authors, based on the intensive field study undertaken at different opencast coal mines in Odisha highlighted the impact of in-seam dirt bands in coal seams on the performance indicators of surface miners which are normalized production rate, diesel and pick consumption for cutting 1000te of material in this paper. Pick consumption was found to vary linearly with the quantum of abrasive material cut. Empirical relations for estimating monthly normalized production, diesel consumption, and pick consumption of surface miners operating in coal seams with intermittent dirt bands with a coefficient of determination (R2) of 0.74, 0.84, and 0.73 respectively were also developed. The developed relations were validated with the field data and the % error was found to be within +20%. This study helps the coal mining companies in the selection of suitable surface miners for achieving targeted production and also for planning inventory of picks and diesel during its operation.

This experimental research analyses tensile and microstructural behaviour followed by Al7475 (Al-Zn) metal alloy with 3 and 6 wt% of composites of B4C. The liquid metallurgical technique was used in this analysis for creating the Al7475 alloy with 3 and 6 wt% percentages of B4C particle composites. Additional techniques such as EDS/SEM were also employed in this analysis to determine the microstructural behaviour. ASTM Standards are followed to study the mechanical behaviour of Al7475 alloy with B4C-reinforced composites. The incorporation of B4C particles into Al7475 resulted in extreme characteristics in the field of the composite material thereby enhancing its maximum application. By combining different materials, the hardness and tensile strength of the composites improved. Tensile fractured surfaces indicated the brittle and ductile mode of fracture behaviour in the Al7075-B4C composites.

Choosing an appropriate heat transfer fluid is a crucial factor in the design of a heat exchange system. A nanofluid is a colloidal mixture composed of a base fluid and nanoparticles. It is a promising heat transfer fluid in various applications due to its improved thermal conductivity and heat transfer rate. The increasing demand and acceptance for nano-fluids as heat transfer fluids in various applications have led to an increase in research investigations on this topic. Nanofluid technology has recently expanded to include the impregnation of multiple nanoparticles in base fluids, known as hybrid or nanocomposites. For this study, we have chosen three distinct nanoparticles and two base fluids to examine their thermo-physical characteristics and heat transmission rate. Nanofluid is prepared via the sonication method. The experiment is used to determine the thermosphysical characteristics of various nano-fluids. The double-pipe heat exchanger is employed to measure the heat transfer rate and efficiency of nano-fluids. Among six samples prepared in the present work, the ZnO2+CNT+TiO2+EG sample had shown reduced kinematic and dynamic viscosities for all the temperature ranges. However, an average value of heat transfer rate was recorded for ZnO2+CNT+TiO2+EG at 675.87 (J/s) for parallel flow and 630.79 (J/s) for counter flow. And the least effectiveness was recorded for distilled water. The hybrid nanofluid demonstrates a superior heat transfer rate and effectiveness in both parallel flow and counter flow applications. Therefore, it may be efficiently utilised in many heat transfer applications.

This study investigates the optimization of quantitative analysis and extraction of copper from rocks in Oman. The focus is on enhancing the efficiency and accuracy of these processes for sustainable mining operations. The research employs Response Surface Methodology (RSM) to identify the optimal conditions for extracting copper using phosphoric acid boiling and thermite mixture methods. X-Ray Diffraction (XRD) is employed to characterize the extracted samples and understand the mineralogical compositions. The RSM analysis revealed the optimal conditions for copper extraction using phosphoric acid boiling. X-ray diffraction analysis of the extracted copper samples showed that the majority of the copper was extracted as metallic Copper (Cu). The optimization of these processes is crucial for improving the efficiency and sustainability of mining operations in the country. X-ray diffraction analysis provides valuable insights into the mineralogical composition of the extracted samples, which can be used to optimize the extraction processes further.

Composites containing metal at least in two constituent parts are metal matrix composites. Another material may also be used like organic compounds or ceramics, in addition to a different metal. In the current work Al5056 aluminium powder is used as the matrix material having an average particle size was about 35±5 μm and Carbon Nanotube (CNT) and Graphene (Gr) are used as reinforcement materials. Hybrid composites are developed using an advanced powder metallurgy technique process. Also, in the existing work microstructure characterization was performed using advanced techniques. Hardness, Tensile and wear tests are conducted as per ASTM standards. Mechanical properties improved with the increase in amalgams in the matrix. The wear surface morphology of Al alloy shows a rough surface with more grooves and ridges compared to the wear surface morphology of Al5056/CNT-Gr hybrid composites. Wear debris results of Al alloy show more debris chips out of the material compared to Al5056/CNT-Gr hybrid composites.

Soil improvement in the most sustainable way is the need of the hour and prime importance for the modern construction industry. Most of the time, it has been observed that the soil below the foundation is not mechanically capable of withstanding the load from the structure, and it might cause the failure/collapse of the structure. To prevent it, various significant soil improvement techniques have been introduced, such as mechanical stabilisation, thermal methods, use of admixtures etc. Ground improvement using admixtures involves the addition of various chemical alternatives to the subsoil to enhance its loadbearing capacity. These procedures also give long-term sustainability regarding the soil's bearing capacity. Various potential scholarly works on ground improvement have been done, i.e., the addition of bentonite, kaolinite, bitumen, rice husk ash, pond ash, lime, and cement into the soil, which has been intensely reviewed. From the combined observed experimental results of several researchers presented in this paper, it can be identified how much improvement of a particular soil property can be made by adding several types of admixtures. A clear idea can be generated as to which type of admixture is most suitable for the improvement of a particular type of soil and which soil properties can be improved by the addition of that admixture.

Research on the study of tectona grandis for adsorption of dyes, extraction of chemicals dissolved in it for pharma industries is studied from many years. Few researchers have explored the use of tectona grandis in thermo-chemical process such as torrefaction, and pyrolysis. But the study to use of Hydrothermal Carbonization (HTC) to convert leaf litter to value added products of tectona grandis for varying process conditions is not performed. This research is focused to ascertain the role of HTC process parameters on hydrochar and biocrude produced from tectona grandis leaf litter. HTC experiments were conducted in a batch reactor. Various process parameters such as temperature and residence time which affects the yield of hydrochar is reported. HTC of yard waste is carried out at 210oC for a residence time of 20 min in a batch reactor which gives the hydrochar yield of 65% with higher heating value of 26.63 MJ/kg. Characterization of hydrochar performed with proximate analysis, ultimate analysis, SEM and FTIR showed that hydrochar properties are better compared to feedstock properties which can be effectively used as solid fuel. The liquid bio crude separated from solid hydrochar is analyzed using UV spectroscopy. It is found to contain the compounds such as 5-HMF, dibenzofuran, naphthalene and anthracene.

The current state-of-the-art review on tool condition monitoring for turning of titanium-based superalloys is presented in this paper. Titanium (Ti) superalloys are widely utilised in aerospace industry, automobile industry, petrochemical applications. Ti superalloys are also used in fabrication of biomedical components due to their outstanding combination of mechanical properties and strong corrosion resistance at extreme temperatures. But these superalloys are difficult-to-cut because to their low heat conductivity, low elastic modulus, high strength, and strong chemical resistance. Literature review highlights the drastic reduction in tool life of titanium superalloys at highspeed and feed rates throughout the machining process. The review paper focuses on (i) various reasons to deploy tool condition monitoring; and (ii) study of tool condition monitoring methods based on machine learning techniques to identify the ideal parameters for the prevention of catastrophic tool failure.

The primary goal of this paper is to design and analyse the entire double wishbone suspension system for a commercial vehicle in order to improve the vehicle’s stability and handling. The suspension system has seen tremendous advancement. A commercial vehicle’s suspension system must be long-lasting, light in weight, efficient, and cost-effective. The vehicle must be able to withstand the harsh off-road terrain environment. As a result, it is critical to concentrate on the stress strain analysis study of the lower wishbone arm in order to improve and modify the existing design.
