For decades, Indian mining operations could treat ANFO as a reliable, low-cost commodity — available in bulk, priced predictably, and rarely a strategic concern. That assumption is being tested. Ammonium nitrate is an energy-intensive product to manufacture, and global supply disruptions tied to energy market volatility in key producing regions...

If you ask a mine manager where their biggest cost-saving opportunities are, blasting rarely tops the list. Fuel, labour, equipment maintenance, explosive prices — these get the attention. Blasting is often treated as a fixed cost: drill the pattern, load the holes, fire the round, move on. Fragmentation Is a...

Rock excavation has been practiced since ancient times, with explosives becoming widely used during the Industrial Revolution due to increasing demand for minerals. Although blasting remains one of the cheapest and fastest methods of rock breaking, environmental concerns, noise, vibrations, and public awareness have increased the need for safer and...

Fragmentation using explosives by blasting is the most economical, cheapest and fastest method of rock fragmentation and loosening material from the host rock, making it suitable for excavation. Blasting performance is generally affected by the structure and rock properties of the rock mass. As mine sizes and excavation activities in...

Effective stemming is a critical yet frequently underestimated factor governing the utilisation of explosive energy in bench blasting. This paper reports the results of controlled field trials conducted at the Sitapuram Limestone Mine, the captive quarry of Zuari Cement Limited, located in Chintalapalem Mandal, Suryapet District, Telangana, India. Stemming plugs...

Blasting is the most essential part of Mining and Civil Engineering and often the cause of most of disputes with the neighbours as the blasting produces Unwanted Ground Vibrations, sound etc. And is often blamed for the damage of the neighbouring properties. Alternates to blasting such as ripping, cutting etc,...

Ask most blast crews what stemming does, and you’ll get a simple answer: it keeps the gas in the hole so the explosive does its job instead of venting uselessly out the top. That’s true, but it’s only half the story. The other half is about physics that most people...
