چکیده
In order to reduce the large rocks produced by blasting of hillside open-pit mine with heterogeneous and complex rock mass in arid area, based on lithology characteristics Dabancheng Limestone Hillside Open-pit Mine Hongshun, Xinjiang, key technology for homogeneous is proposed this paper. We can conclude from experiment that (1) it preferable have a detonation network realizes multi-stage millisecond differential, multiple combinations detonating unit forms, variable blast hole connection lines; (2) parameters, charge structure interval are optimized make efficiency be effective continually; (3) radial tensile stress reflected wave enhanced breaking mechanism complicated revealed.

A comparison between effects of earthquake and blasting on stability of mine slopes: a case study of Chadormalu open-pit mine
Dynamic slope stability in open-pit mines still remains a challenging task in the computational mining design. Earthquake and blasting are two significant sources of dynamic loads that can cause many damages to open-pit mines in active seismic areas and during exploitation cycles. In this work, the effects of earthquake and blasting on the stability of the NW slope of Chadormalu mine are compar...
متن کاملImplementation of Hyperbolic Tangent Function to Estimate Size Distribution of Rock Fragmentation by Blasting in Open Pit Mines
Rock fragmentation is one of the desired results of rock blasting. So, controlling and predicting it, has direct effects on operational costs of mining. There are different ways that could be used to predict the size distribution of fragmented rocks. Mathematical relations have been widely used in these predictions. From among three proposed mathematical relations, one was selected in this stud...
متن کاملA genetic algorithm approach for open-pit mine production scheduling
In an Open-Pit Production Scheduling (OPPS) problem, the goal is to determine the mining sequence of an orebody as a block model. In this article, linear programing formulation is used to aim this goal. OPPS problem is known as an NP-hard problem, so an exact mathematical model cannot be applied to solve in the real state. Genetic Algorithm (GA) is a well-known member of evolutionary algorithms...
متن کاملEffects of Mine Blasting on Residential Structures
Blasting is common in the coal industry to remove rock overburden so that the exposed coal can be mechanically excavated. The ground vibrations and air blast produced by blasting are often felt by residents surrounding the mines. There has been a trend for regulatory authorities, especially those concerned with the environment, to impose low limits on blast vibration levels in response to commu...
متن کاملApplication of simulated annealing for optimization of blasting costs due to air overpressure constraints in open-pit mines
Estimating the costs of blasting operations is an important parameter in open-pit mining. Blasting and rock fragmentation depend on two groups of variables. The first group consists of mass properties, which are uncontrollable, and the second one is the drill-and-blast design parameters, which can be controlled and optimized. The design parameters include burden, spacing, hole length, hole diam...
