Wireless communication systems continue to improve in the mining pit and will soon remove the pickup truck from the process, sending the data directly to the maintenance engineers desk. No user has yet reached the point that it will allow the vibration analysis to automatically trigger a repair order, insisting that an analyst review it first.
The vibration reduction with the delay control in blasting is shown in Fig. 13.4a according to which the level of vibration with 25 Ms decreased to 20 per cent that of 50 Ms at 50 m distance. Similarly low frequency waves caused more severe damage to the houses in
In an open-pit mine slope, rock mass has multiple joint structures and blasting operations have an obvious influence on its stability. Therefore, accurately predicting the blasting vibration is necessary to ensure slope stability.
surface coal mine, because greater volumes of material must be moved requiring larger blast designs than the trench. Often blasts are hundreds of feet away, and the ground movement begins to slow its rate of travel due to the distance. Even when farther away the ground vibration will reach your property before the air overpressure, consequently

In this study, vibration sensors were used to measure blast-induced ground vibration PPV. Different evolutionary algorithms were assessed for predicting PPV, including the particle swarm optimization PSO algorithm, genetic algorithm GA, imperialist competitive algorithm ICA, and artificial bee colony ABC. These evolutionary algorithms were used to optimize the support vector ...
Feb 02, 2013 One of the most fundamental stages in open pit mining is drilling and blasting. A good fragmentation and a minimum ground vibration are characteristics of a successful drilling and blasting operation. In this study, 78 blasting events of AlvandQoly limestone mine located in Kurdestan cement company in west of Iran were investigated. The vibrations induced blasting was recorded by
The potential air-blast and vibration impacts related with the Chimiwungo open pit of Lumwana mine are typical for a large open -pit mining operation and generally include Operation of lightand heavy vehicles for transportation of personnel, materials and equipment within the site.
Open cast mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow pit. Walls of the pit are generally blast mined, creating ground vibrations and resulting in dust generation and water, air, and noise pollution.
Mining can create significant noise andor vibration through blasting in both open pit and underground mines ore and waste rock truck traffic on the mine site ore stockpiling, screening, and crushing and truck or rail traffic bring consumables to the mine site and shipping product from the mine

Jun 26, 2016 This methodology has been used in surface coal mines to protect important infrastructure power structures, gas lines, etc. and in metal mines to control vibration levels to minimize the impact of blasting on the performance of large open pit slopes. Introduction. In the mining production cycle, blasting is the most economical and efficient ...
Methods In Open Pit Mining Activities Mohammed Mnzool Mohammed, Abstract A failure at mining sites is a basic cause of death, serious injuries, economic and production losses. As open pit mines get larger and deeper with its related high risk of failure and consequences, slope monitoring methods become more important.
Aug 06, 2020 During the extraction of minerals in open pit mines, blasting operations are carried out producing shock waves and therefore vibration and noise that can be perceived by the inhabitants of nearby settlements. Vibration levels will depend on a number of factors and variables that mining planning must consider.
In open-pit to underground mines, partial collapse of surficial rock mass always occurs because the open-pit slopes are subjected to underground blasting mining operations , which trigger a serious threat to the workers and equipment. In order to ensure the safe production, it is the key technical problem to determine the blasting vibration ...
