Longwall mining is a major method of underground coal extraction worldwide. In India, coal accounts for over 50% of energy production, though most is still extracted via opencast mines. Longwall mining was introduced to India in the 1970s but has seen limited improvement and adoption since. Key longwall equipment includes powered roof supports, shearers, conveyors, and monitoring is important for strata control and safety. Organizing longwall panels and transferring equipment between panels is a complex operation involving dismantling, transport and reassembly of machinery.
This document discusses longwall mining, an underground coal mining method. It provides details on longwall mining equipment and operations. In India, longwall mining has faced challenges with low production rates. Issues included improper site selection, faulty planning, and support deficiencies.

There are several stages in the coal handling process at a power plant: 1) Coal is delivered by rail, road, or ship and unloaded. 2) The coal may then be prepared through processes like crushing or grinding. 3) The coal is transferred to storage areas using conveyor belts or other equipment. 4) Coal is stored in piles or bunkers until needed. 5) In-plant equipment then moves the coal to furnaces where 6) weighing and measuring ensures the proper amount is fed to boilers for 7) furnace firing to generate power.
Clean coal technology aims to make coal a cleaner energy source. It discusses two key technologies: coal washing and integrated gasification combined cycle (IGCC). It then analyzes issues for China in transferring clean coal technologies from other countries, including economic problems like pricing mechanisms and limited investment, as well as political challenges such as intellectual property rights and discriminatory policies. Technology transfer efforts also face social and managerial difficulties within Chinese companies.
Underground mining methods include:
1) Room-and-pillar mining which leaves pillars of unmined ore to support the mine but has a low ore recovery rate.
2) Longwall mining which uses temporary support that is removed allowing the worked area to collapse and maximize ore recovery but can cause subsidence or rockbursts.
3) Choice of mining method depends on factors like the orebody shape and orientation, grade, depth, and impacts on surface environment and land use.
Sampling and analysis for feasibility studies and mineral processingBasdew Rooplal
This is an overview of some aspects of sampling involved in feasibility studies for mining and mineral processing. Some small scale bench test work is also covered.
The document discusses mineral beneficiation and comminution. It defines mineral beneficiation as the separation of valuable minerals from gangue in ore. Comminution, or size reduction, is the primary operation in mineral dressing and involves crushing and grinding the raw ore to liberate valuable minerals. The key steps in comminution are primary crushing, secondary crushing, coarse grinding, and fine grinding. Jaw crushers and gyratory crushers are used for primary crushing and reduce ore sizes from about 1 meter to 100 mm.

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.
