Among various types of cities, mining cities have special features including a high concentration of industrial activities associated with the exploration, extraction, refining, processing and export of groundwater resources, the risk of reduction and termination of non-renewable resources, high degree of environmental pollution, high production of domestic and industrial waste and social issue...

Ground water and surface water create a range of problems in lignite mining utilizing surface mining methods. In order to create a safe and economic mining environment, it is essential to carry out mining after dewatering the rock mass surrounding the lignite mines by advance dewatering techniques. This paper briefly describes the ground water regimes including pressure gradients associated wit...

In the process of data mining, techniques used, and results gathered, became ethically or even legally questionable due to the concern of the violation of individuals’ privacy when specific information is obtained, manipulated, and disseminated by other entities without an individual’s knowledge or consent. In other words, it is not the concern of what data is being mined, but more so regarding...

This study uses a vector autoregression (VAR) model to analyze changes in pollutants among different mining industries and related policy in China from 2001 to 2014. The results show that: (1) because the pertinence of standards for mining waste water and waste gas emissions are not strong and because the maximum permissible discharge pollutant concentrations in these standards are too high, am...

Among all the 119 counties (cities, districts) in Shanxi province, China, there are 94 counties with coal resources, and 80% are resource-based mining cities. Since 2008, a number of small coal mines have been shut down due to the integration of coal resources in Shanxi Province, as well as merger and reorganization of large state-owned coal mining enterprises are under efficient operations. Th...

abstract tax can be discussed from various aspects and in the meantime, evaluation the tax system performance is very important. this article try to point this out in 2005 and 2008 (the second and final year of the forth development plan) in the iranian economy and in provinces separately. to enable this comparison and homogeneity, iranian provinces are divided into three groups (developed, les...

Dispersion modeling approach was applied for the determination of SO2 and NO2 pollution in the ambient air. The model performance has been evaluated by comparing the measured and predicted concentrations of SO2 and NO2. This has been tested to measure the air quality and predicted incremental value of pollutant’s concentrations by using the data avail...

The paper approaches certain aspects regarding the involvement of the banking and industrial capital in the development and modernization of gold mining during the existence of „Mica” Company (1920-1948). The paper presents the political and economic factors contributing to the positive results in the field. It also provides examples of the way in which the banking and industrial capital was in...

This paper discusses an industrial case study in which data mining has been applied to solve a quality engineering problem in electronics assembly. During the assembly process, solder balls occur underneath some components of printed circuit boards. The goal is to identify the cause of solder defects in a circuit board using a data mining approach. Statistical process control and design of expe...
