Air is the worst affected environmental matrix, and it can carry the harmful effect of pollutants generated from mining activity even to distant places. The present study was undertaken to estimate the emission of particulate matter (PM 2.5 and PM 10) from different activities undertaken in stone quarrying in Mahendragarh, Haryana. The results ...

Governments and banks must help farmers get access to credit and support in implementing erosion prevention. This is not only a good deal for the farmer, but for the whole community. The cost of erosion prevention is far lower than the price of land restoration and rehabilitation, which one source estimated to be around $1,500–$2,000 …

The diameter, depth, number, and spacing of boreholes in blasting quarrying require careful consideration to achieve the best results. The type of explosive used determines the diameter of the hole. For explosives that come in standard-sized cartridges, the diameter must be slightly larger than the cartridge size to allow for easy insertion.
