Differential SAR Interferometry (D-InSAR) is an effective tool in monitoring land subsidence because of its greater coverage area and better resolution of height change. A series of Japanese Earth Resources Satallite-1 (JERS-1) images from 1992 to 1998 has been used in monitoring the mine subsidence in the test site of this study, one of the important coal mining areas in China. D-InSAR procedu...

Recently lots of researchers are focusing their interests on the development of summarization systems from large volume sources combined with knowledge acquisition techniques such as infor mation extraction text mining or information re trieval Some of these techniques are implemented according to the speci c knowledge in the domain or the genre from the source document In this pa per we will d...

The Itai-Itai disease case is one of four major pollution-related lawsuits occurring in Japan after World War H. This paper, which is based on investigations of the pollution source, the Kamioka mine, considers (1) the history of the disturbances to the environment caused by the Kamioka mine; (2) the Itai-Itai disease suit; (3) the pollution nprevention measures and methods of the Kamioka mine ...

water has an important role in creating pollution problems in the mining regimes influencing the surrounding surface environment. the purpose of this study is to make an assessment of groundwater quality in an underground mine site in portugal with a view of determining the pollution potential of groundwater. in the corresponding surface area of this underground mine, intersections of fou...

Plans to open a globally significant gold mine at Roşia Montană, in the Transylvanian region of Romania, have led decades controversy and struggle. This paper explores different understandings extraction amongst advocates for opponents over last two decades. We discuss shifting roles capital, state, civil society organizations, local community time, arguing need distinguish between their positi...

In coal mine gas extraction in China, the current hydraulic permeability enhancement measures generally have complex processes, low adaptability, long operation time, and high labor intensity. This makes it challenging to meet requirements of mining enterprises for safe efficient mining, there is an urgent need develop new technologies enhance production. paper proposed integrated drilling stam...

Mining for resources extraction may lead to several geological and associated environmental changes due to ground movements, collision with mining cavities and deformation of aquifers. Geological changes may continue in a reclaimed mine area, and the deformed aquifers may entail a breakdown of substrates and an increase in ground water tables, which may cause surface area inundation. Consequent...

An orebody model constitutes a threedimensional accumulation of mining units (blocks). The available metal content in a mining unit and the economic parameters, such as metal price, mining cost, processing cost, marketing or selling cost, as well as the metallurgical recovery, are used to calculate the economic value of a particular mining block. A mining block with a positive value is classifi...
