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 …

Reliability Analysis of a Dragline for Productivity Improvement – A Case Study
Abstract: Productivity of dragline is affected by its availability, reliability, and maintainability. The failure of components of dragline leads to the failure of dragline system. Effective maintenance planning can prevent these unwanted failures in the capital-intensive draglines and can improve its productivity. This paper discusses the possible causes for failure of various components of dragline and possible ways for improvement of performance of dragline so as to reduce its downtime. In …
