Optimization of Maximum Charge Per Delay Using Site-Specific Ground Vibration Prediction Models for Safe Blasting in an Opencast Coal Mine
Abstract: Drilling and blasting are critical operations in opencast coal mining that directly influence rock fragmentation, excavation efficiency, and production performance. However, excessive blast-induced ground vibration and air overpressure can create safety and environmental concerns, particularly in mines located near villages and sensitive structures. The present study was conducted at Chapapur-II Colliery, Mugma Area, Eastern Coalfields Limited (ECL), with the objective of optimizing blast design through the determination of safe maximum …

Effect of Ground Granulated Blast Furnace Slag as Partial Cement Replacement on Compressive Strength of Concrete
Abstract: AbstractThe main objective of this research work is to determine the optimum replacement percentageof GGBS which can be suitably used. To fulfill the objective, various properties of concreteusing GGBS have been evaluated. Mix design has been arrived for M25 concrete. Fineness,specific gravity (cement and GGBS), normal consistency, initial and final setting time andcompressive strength of cement have been found out. Particle size distribution, bulking of fineaggregate, specific gravity, water absorption …

ANN Approach to Forecasting the Strength of Nano Silica Incorporated Geopolymer Composite
Abstract: Coal and steel industry by-products, such as fly ash (FA) and blast furnace slag (GGBS), have gained significant attention as precursors for geopolymer concrete (GPC) due to their high aluminosilicate content, offering a sustainable alternative to conventional cement. Nano silica (NS), recognized for its exceptional pozzolanic activity and ability to refine microstructure, has shown potential to enhance the mechanical and durability properties of GPC. This study investigates the influence of …
