The two most frequently heard terms in the mining industry are safety and production. These put a lot of pressure on blasting engineers crew to give more while consuming less. key achieving optimum results is sophisticated bench analysis, which must be combined with design blast parameters for good fragmentation safe ground vibration. Thus, unique solution forecasting both reduced vibration usi...

Rock blasting is one of the most common and cost-effective excavation techniques. However, rock has various negative environmental effects, such as air overpressure, fly rock, ground vibration. Ground vibration hazardous these inevitable impacts since it a impact not only on environment surrounding area but also human population itself. The PPV critical base parameter practice for understanding...

Ground vibration is one of the most unfavourable environmental effects blasting activities, which can cause serious damage to neighboring homes and structures. As a result, effective forecasting their severity critical controlling reducing recurrence. There are several conventional predictor equations available proposed by different researchers but them based on only two parameters, i.e., explo...

Recent studies suggest that the pressure changes occur at the rates of 0.5 to 1.5 kHz. Therefore, studying brain tissue at blast-rate deformations requires a test method with loading duration of about 1 ms. Although the material properties of brain tissue have been studied since 1960’s, a limitation of the previous studies is that in most of them the strain rates were below 100 s -1 ; making th...

The general transmissivity law of ground vibrations was studied, and a user-friendly methodology for determining the behavior generated in any rock mass is proposed. study based on single blast trench excavation, analyzing vibration components recorded from two fixed locations. attenuation main variables according to legal requirements, frequency peak particle velocity (PPV), are defined with t...

blast (magnaporthe grisea) is the most important disease of rice in mazandaran province, north of iran, which causes severe damages annually on susceptible cultivars. tarom mahalli is a local aromatic cultivar with high cooking quality and marketability, but very susceptible to blast. to protect this cultivar and similar susceptible cultivars against rice blast, farmers have to use high amounts...
