As fly rock is a critical issue in mining and construction industry, hence it becomes more so important to learn the causes for generation of flyrock and the mitigation measures. This paper deals with causes of fly rock, hazards associated with flyrock and precautions to be taken to control them with the help of a case study at a construction site.

Solution mining can substitute for conventional shaft mining in some potash deposits at depths of more than 1,100m, which is the current limit for conventional potash mining. It is not an all-encompassing mining alternative to be used whenever potash zones are too deep or too variable for conventional mining methods.

Solution mining techniques are often cheaper than conventional methods, such as open pit or underground mining. The average capital expenditures for a solution mine is US$1,000/t, whereas for an underground mine it is US$1,400/t.. The process avoids large investment costs and the difficult stage of excavating large volumes of materials, which …

When the potash to be extracted is at a depth of 1000 m or deeper and/or the potash it is located in sedimentary rock then solution mining provides a cost effective, efficient and safe way to extract the resource. Added benefits of solution mining include: lower up-front capital cost, no underground workforce, relatively lower volumes of waste ...

A group of mining companies conducted an empirical study on flyrock in 2767 mine sites. The study showed that, over a period of 10 years, 447 flyrock incidents took place. 141 of these incidents caused injuries and 5 of the 141 injuries were fatal. Estimate the probability of a fatality associated with a fly rock at a single mine per annum.

Underground hard-rock mining accounts for 40 percent of global mining operations but only 12 percent of run-of-mine (ROM) production. 1 Run of mine is ore that is mined and crushed. In this article underground mining refers to underground hard-rock mining; thus, underground soft-rock mining, such as coal, is excluded.
