An Analysis and Prevention of Flyrock Accidents in Surface

Flyrock has caused serious injury and death to employees, visitors, and neighbors in the mining industry. In juries due to flyrock and lack of blast area security account for 68% of all blasting related injuries in surface coal, metal, and nonmetal mines during the period 1978 2001 [Verakis & Lobb, 2003].

Preventing & Controlling Flyrock with Blast Mats & Shields

If you are involved in the world of mining or construction, blasting is inevitable. Whether you need to free mineral from rock, remove existing structures or otherwise reform the environment to achieve your goals, there are situations where the best, or the only solution, is blasting — which means explosives.

Flyrock Dangers & Best Practices | Mine Safety and Health

24.03.2016· On Monday, July 16, 2007, a mechanic with 20 years of mining experience was fatally injured at a surface mine when he was struck by flyrock from blasting operations. The victim and another mechanic had just completed their shift in an equipment parking/service area approximately 1,500 feet from the area being blasted.

Fatal Accidents Due To Flyrock And Lack Of Blast Area

where rock fragmentation is essential for the success of the project. About 5.25 billion pounds of explosives were used in the United States during 2001. Out of this, coal and nonmetal mining consumed about 4.29 billion pounds [USGS, 2003]. A major part of this consumption was related to surface mining. Although blasting presents numerous hazards, the mining industry considers blasting an

Safety Evaluation of Blasting Mining and Blasting

mining show a value of 25%, and the Indian mines show a proportion of 20% [5,6]. So it is important to study the reasons of flyrock and to seek counter measures. However, for the complicated mechanism, the flyrock is generally considered with experience in practice. Recently, some studies have been carried out to show that the major causes of flyrock are inadequate burden, inadequate stemming

Understanding charging and blasting solutions for mines

However, in underground mining, blast mats are not used as it is not necessary to suppress sound and rock can fly freely. As detonating explosives releases toxic gases, such as nitrogen oxide (NO), nitrogen dioxide (NO 2 ) and carbon monoxide (CO), workers must wait until gas has dissipated and the area is ventilated before resuming work or seriously risk their lives and health.

Underground Hard Rock Mining | RAMJACK

Fundamentally, underground hard rock mining has changed very little over the last century or so. Shafts and tunnels are excavated and constructed to allow miners to reach an ore zone, the ore body is broken up using blasting or other methods, and the resulting material transported along tunnels and up shafts to the surface where it is crushed and processed.

Dilution and ore recovery QueensMineDesignWiki

As a mining project is developed from conceptual to production phases, there exist a variety of uncertainties and difficulties that affect the operation’s designs and economic value. A notable design parameter to be taken into account is the factor of dilution. Dilution is the waste material not separated from the ore in the stages of mining, and is sent to the processing plant. It is
