The model is based on the back-analysis of a comprehensive experimental program that included the direct measurement of the zone of crushing from 92 blasting tests on concrete blocks using two commercial explosives. The concrete blocks varied from low, medium to high strength and measured 1.5 m in length, 1.0 m in width and 1.1 m in …
We have produced a probabilistic seismic hazard map showing peak ground accelerations in rock for India and neighboring areas having a 10% probability of being exceeded in 50 years. Seismogenic zones were identified on the basis of historical seismicity, seismotectonics and geology of the region. Procedures for reducing the incompleteness …

Mining and quarrying for minor minerals impart significant economic, environmental and social impacts in and around the affected areas. The problem is severe in the small river catchments as the effective area available for assimilating negative impacts of the activity is minimal, compared to large river basins. To address these issues, an …
Propel manufactures stationary, skid mounted and semi mobile plants between the capacities range of 150 – 600 TPH. Propel crusher equipment are available between 150-200-400 TPH ranges. Another south India based mining conglomerate, Puzzolana Machinery Fabricators has developed new crushers (sanders). Mr.

Hard rock excavation affects excavation efficiency. During excavation, the cutoff teeth of the tunnel boring machine are severely worn or even fractured. However, the traditional blasting methods of excavation can lead to various safety problems. A new kind of stone crusher is urgently needed in practical engineering. In this study, the finite …
A senior geologist in the department of mines and geology, Udupi district, said that 22 safe zones are identified in Karkala taluk in 153.20 acre land, 3 zones in Kundapur taluk in 15.30 acre land ...
The Pachami crushing zone in eastern India is located 250km north of Kolkata, the capital city of the state of West Bengal. A few years ago, it was a nondescript rock crushing area, with operators processing …
India. India's crushing rock capacity may be the fastest growing in the world. The market demand of 5 billion tons and per capita consumption is 3.7 tons. The demand will increase by double digits in the next few years. The main problem facing and actively solved the industry is the depletion of the natural sand resources.
A stone crushing plant is primarily involved in the manufacture of aggregates of various sizes (coarse aggregates, crusher run, rock sand and other fine aggregates) from basalt …
The present study focused on environmental impact assessment (EIA) due to aggregate quarrying and crushing activities at four selected mining/crusher clusters in the middle catchment of Dwarka river basin of Eastern India. EIA is done both spatially and cluster wise considering the impacts of 10 number of influencing factors on 12 number of …

A stone crushing plant is primarily involved in the manufacture of aggregates of various sizes (coarse aggregates, crusher run, rock sand and other fine aggregates) from basalt boulders. Coarse aggregates are usually used in ready mix concrete and asphaltic concrete. Crusher run is used for the bases and sub-bases for road making.
An automated method for determining the zones of rock crushing in the collapse is described. It is based on an analytical method for determining the granulometric composition of blasted rocks in ...
nation of the crushing zones sizes of a blasted block. With the help of this program, zones of small, medium and large crushing of the blasted block can be quickly and fairly accurately determined under various parameters and conditions of blasting rock masses. Locations of the blasted block crushing zones thus established serve as a tool for ...
