The discharge of mine water containing sulphate may pose potential ecological risk to receiving waters. In this paper, we demonstrated the application of a risk-based approach to managing sulphate discharge using a coal mine in the Bowen Basin (Australia) as a case study. This approach integrates information on sulphate concentration and its ecological impact to quantify the risk and evaluate t...

Background : Many telecommunication companies (telcos) today have actively started to transform the way they do business, going beyond communication infrastructure providers and repositioning themselves as data-driven service providers to create new revenue streams. New business opportunities, notably in terms of market research, can be realised using the telco data especially when it is comple...

Various studies on consumer purchasing behaviors have been presented and used in real problems. Data mining techniques are expected to be a more effective tool for analyzing consumer behaviors. However, the data mining method has disadvantages as well as advantages. Therefore, it is important to select appropriate techniques to mine databases. The objective of this paper is to know consumer beh...

AMd is recognized as one of the most serious environmental problem in the mining industry. the problem of acid mine drainage (AMd) has been present since mining activity began thousands of years ago. Mining activity has disrupted the hydrology of mining areas so badly that it is extremely difficult to predict where water would eventually re-emerge. its causes, treatment have become the focus of...

There is no doubt that vehicle operators of heavy equipment have to accomplish difficult tasks. The increase in mine productivity has led to a proportional increase in equipment size. Most vehicles have considerable blind spots, due to scale alone. Combine normal variations in environmental conditions, in-vehicle management systems, navigation systems and radio communications; the most experien...

BACKGROUND In China, over 80% of all work-related deaths in the mining industry occur in coal mines and human factors constitute 85% of the direct causes of coal mine accidents, which indicates that significant shortcomings currently exist in the safety behavior management of Chinese coal mine workers. We aimed to verify the impact of human psychological behavior in coal mine accidents systemat...

Coal resource is the main primary energy in our country, while Shanxi Province is the most important province in resource. Therefore Shanxi is an energy base for our country and has a great significance in energy strategy. However because of the heavy development of the coal resource, the ecological environment is worsening and the farmland is reducing continuously in Shanxi Province. How to re...

The dominant working structure of an underground mine is a set of interconnected tunnels which provides access to ore zones and haulage of ore from the designated ore zones to the mill. This set of interconnected tunnels forms a network. We describe a mathematical network model and the modelling features of our two software tools for designing underground mine layouts that minimise associated c...

this paper estimates the effects of increase in iran’s non-oil exports on its economic growth as well as sectoral outputs, using a single country, comparative static, exogenous policy computable general equilibrium (cge) model. the paper also investigates the share of tradable sectors in reaching to the targeted growth rate (8%) in 5th socio-economic development plan. for this purpose, the para...
