In India many of the mines are working on with opencast mining and most of the mining operations are performing with drilling and blasting. The opencast working plays a crucial role in mining because of the improved productivity, recovery and safety of mining operation. The topic is OPTIMIZATION OF BLASTING OPERATION.

Introduction. This paper discusses a geotechnical study and a slope design of a proposed 170 m deep leadzinc opencast mine situated in Rajasthan state, India. The open pit is 1,500 m long and 500 m wide. The ore body has been proved for a length of km and to have 60 million tonnes of ore reserve. As the ore body is steeply dipping, the ...

billion in 2018. The remaining 2% of domestic iron ore was produced for nonsteel end uses. Seven openpit iron ore mines (each with associated concentration and pelletizing plants), and three iron metallic plants—one directreduced iron (DRI) plant in Louisiana and two hotbriquetted iron (HBI) plants in Indiana and Texas—operated during

The mining value chain— which includes everything from extracting raw material to delivering products to customers—is the backbone of the industry. Companies that manage their value chain well can establish a significant source of competitive advantage and value creation. By contrast, those that neglect their value chain are likely to ...

In this study, vibration sensors were used to measure blastinduced 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 ...

Mechanical extraction methods employ mechanical processes in a relatively dry environment to mine minerals from the Earth's crust. In contrast, aqueous methods involve water, or occasionally other liquids, to extract minerals. The surface mining methods can be classified as shown here. We will discuss the mechanical extraction methods in this ...

Therefore, new methods for dump design optimization are of the highest priority in mine planning management. This paper presents a methodology to model and optimize the design of a mine dump by minimizing the total haulage costs. The proposed methodology consists of: (1) formulation of a dump model; (2) solves by using linear programming and ...
