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...

Sequential pattern mining and sequential rules mining are important data mining task for wide application. Its use to find frequently occurring ordered events or sub sequence as pattern from sequence database. Sequence can be called as order list of event. If one item set is completely subset of another item set is called sub sequence. Sequential pattern mining is used in various domains such a...

Original scientific paper Mining near the fault structure can easily lead to the fault activity and induce serious geological disasters, posing a serious threat to coal mine safety production. To reveal the surrounding rock activity characteristics induced by near-fault mining, taking Qixing Coal Mine in China as the engineering background, the contrastive analysis of the microseismic events in...

We developed an intelligent information visualization tool to enable public health officials to detect healthrelated trends in any geographic area of interest, based on Twitter data. Monitoring emergent events such as natural disasters, disease outbreaks, and terrorism is vital for protecting public health. Our goal is to support situation awareness (SA) for personnel responsible for early dete...

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...

Gas disasters, such as coal and gas outburst overflow, always occur during the mining of steep extra-thick seam in horizontal, fully mechanized, top slice caving (HFMTCSC) method. To solve these issues guarantee safe efficient Yaojie No. 3 mine, 3DEC software was used this work to investigate overburden movement collapse law well stress redistribution coal-seam deformation characteristics below...

Rockburst is one of the main dynamic disasters in coal mines; it great significance to accurately evaluate risk zoning rockburst for mine safety construction and pressure relief design. Taking Gaojiapu Bingchang mining area Shaanxi Province as study area, this paper quantifies complex geological structure based on fractal theory establishes evaluation model index by LS-FAHP-CRITIC method combin...

Coal mine gas disasters have severely restricted production safety. Improving extraction efficiency can effectively reduce disasters. Scholars confirmed that CO2 successfully displaces coal seam CH4. This study conducted displacement and in situ experiments compared drainage under different injection pressures. The indicated CH4 rates increased pressures while the ratios decreased. pressure had...

The prediction and prevention· of mine disasters are crucial to identifying the stress strain state coal using ultrasonic response characteristics. In this study, testing experiments primary structure samples under uniaxial loading were conducted a low-frequency rock physics measuring device. Based on experimental results, study focused analyzing relationship stress–strain with velocity quality...
