Flyrock is considered as one of the main causes of human injury, fatalities, and structural damage among all undesirable environmental impacts of blasting. Therefore, it seems that the proper prediction/simulation of flyrock is essential, especially in order to determine blast safety area. If proper control measures are taken, then the flyrock distance can be controlled, …
or quarry site the potential hazards are increased by the need to handle sensitive initiating explosives while working in a harsh environment. The blasting process must be managed in a way that minimises the risk of the unplanned detonation of explosives, and associated undesired outcomes, and uncontrolled blast behavior at the time of firing.
The exposure to respirable crystalline silica found in granite dust presents significant health hazards to quarry workers and nearby communities, including silicosis and various respiratory ailments. This study evaluates the efficacy of various pollution control measures implemented in granite quarries. It aimed to provide a comprehensive critical …

Quarrying of rocks and minerals has contributed to the economic development of many nations. However, dusts generated from these quarries have caused environmental and health challenges. Health risk assessment of the environments around quarries in southwestern Nigeria was, therefore, carried out to delineate the effects of quarrying on the environment. …
It was found that the GA-based model was more accurate than the ICA- and PSO-based models, and it was concluded that FRES is a very useful for both risk assessment and prediction of flyrock. Strict control of the environmental impacts of blasting operations needs to be completely in line with the regulatory limits. In such operations, flyrock control is of high importance …
Blasting is the most cost effective methodology to break rock for mining or civil engineering applications. A good production blast will break only the rock that is needed to be removed, leaving the host rock with minimal damage. ... Proposed steps for the assessment of the rock damage due to blasting. ... The mechanics of rock breakage. Pit ...
Blasting safety involves assessing, controlling, monitoring, and managing risk throughout the entire process of a blast, from site selection to clean-up. It's essential for all members of the blasting crew to have a thorough knowledge of the dangers involved and to utilize protective gear, including glasses or face shields, hard hats, hearing ...
The desk study is a very important stage of preparing the Blasting Assessment Report (BAR). The desk study involves the collection and review of information required for the planning of the proposed blasting works and the assessment of any impact and risk to the surrounding area. 1.1 Gathering Information from Relevant Authorities
Risk assessments are conducted before activities commence on a bench, in which risks are discussed and controls implemented. Safety is never compromised and the use of industry-leading bench practices has led to …
Risk Assessment is to be performed on a regular basis. The goal for each risk assessment session is to identify hazards, determine risk rating and controls, and to ... of the quarry fault zone by pre-split blasting. This may, however, be confirmed through slope stability studies The movement of the slope shall be observed by installing subsidence
Blasting is a common technique for rock breakage in the numerous civil and mining engineering activities such as excavation, leveling, and tunneling. However, this technique has several environmental issues, such as ground vibration. More importantly, the peak particle velocity (PPV), as the main indicator of ground vibration, should be considered by …
The risk of vibration damage is evaluated, taking into account the magnitude, frequency and duration of the vibration with consideration of the type of building which is exposed. A frequency-based vibration criterion is given, which is judged to give a minimal risk of vibration induced damage. The guide value increases with increasing frequency.
