The blast-induced ground vibration prediction using scaled distance regression analysis is one of the most popular methods employed by engineers for many decades. It uses maximum charge per delay and monitoring as major factors predicting peak particle velocity (PPV). established that PPV caused which varies with site geology. While conducting a production blasting, waves induced blasting different holes interfere destructively each other, may result in higher than predicted value analysis....
Rock mass in open cast mines is generally fragmented by blasting. The sudden release of explosive energy not only fragments rock but also generates undesirable nuisances such as ground vibrations, fly rock, dust, toxic fumes, back break, air overpressure (AOp) etc. AOp can vibrate civil engineering structures, shatter glass windows and doors, adversely affect living quality. present study strives to develop a reliable artificial intelligence model (AI) for predicting some Indian mines. For...
The blast-induced ground vibrations can be significantly controlled by varying the location and orientation of point interest from blast site. waves generated due to individual holes get superimposed resultant peak particle velocity (PPV) generates. With sequence blasts on site, superimposition angle wave changes hence results in significant variation PPV. with respect initiation resulting lowest PPV needs identified for any By knowing contour vibration mine sites, it is possible reduce...
Experimental results for the deposition of low dielectric constant Parylene-N and Parylene-F films are explained by a mechanism based on bulk phase diffusion reaction in film. The rate decreases significantly as time increases ultimately achieves steady state. Very favorable agreement with experiments at substrate temperature −10 °C is obtained parylene-F kf=5×10−5/s, coefficient Df=1.3×10−8 cm2/s. In contrast, much higher room kf=0.16/s predicted after very small period (tss<4/kf=25...
Explosives are used as a source of energy to break the rock mass.Majority explosive is lost in form ground vibrations, noise, air blasts, etc. Blast-induced vibration influenced by many parameters such mass, characteristics, blast design etc.The prediction blast-induced using regression analysis sometimes becomes too conservative leading difficulties operating mine efficiently and safely.Scaled distance approach still very reliable predicting approach, but there other alternative approaches...
Geological sequestration of CO2 in a coal seam is considered an attractive option to reduce the carbon footprint. It has additional advantage enhancing recovery coalbed methane, which less sorption affinity toward comparison CO2. Desorption gases from controlled by various parameters, including reservoir depth and rank. A representative factor for desorption diffusion time. indicator helps estimation evaluation gas movement seam. Coals exhibiting high time allow greater quantities injection...
Abstract Working against nature and uncertain environment makes underground mining a hazardous profession. Every year hundreds of miners lose their valuable lives due to mine hazards. Increasing demand for coal necessitates the extraction at higher rate. As result, easily minable shallow deposits are depleting speedily, in near future, deep seated will be left by methods. With rising depth deployment high-capacity machines, increasing heat stress becomes major hazard posing threat miners’...
