This paper presents all the rock mechanics studies carried out at an underground metal mine in Kadapa, Andhra Pradesh. The rock mechanics investigations in this mine include optimization of pillar dimensions by numerical modeling, the feasibility of Hang-wall lode mining at shallow depth, support design for deeper levels, instrumentation to monitor the strata for an experimental hang wall stope. The main aim is to improve extraction ratio and the mine safety levels from these rock mechanics studies to develop a mine. The Effect on the linear advance in both Footwall lode and Hang-wall lode is studied, monitored and found that there is almost 25 % increase in Total cost per round of blast due to difficult Geo-mining conditions and affecting total cost per tonne of ore extracted from Hang-wall in contrast to Footwall lode development and safety aspects. A critical case study with Techno-Economic Cost analysis in view of their Geo-Mining conditions has been discussed.
The present study attempts to highlight the overview of the regulatory reforms undertaken by Government of Rajasthan and also investigates the impact of COVID-19 on the small businesses of the state. The study is based upon primary survey. The result of the survey depicts that the regulatory reforms undertaken by the state have positive effect on the businesses, though the existing reforms could only provide limited support to the losses incurred by business during the time of pandemic. The results highlight that the key challenges faced by all the businesses include repayment and acquiring loans, payment of wages and salaries, weakening of demand and retaining of workforce. The effective ways to support the revival from losses include technological innovations, increase the sales and demand for goods, lowering of the cost to business along with the incentives and bailout packages given by the government. The study gives the perception of businesses that can help policymakers and public representatives to design state-specific strategic plan for the revival of businesses from the losses caused during the pandemic.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
