Micro seismic (MS) events are closely related to underground rock mass crack, which has a direct relationship with the mining activities. With MS monitoring, the active area in rock mass can be found so as to instruct the mining work and to prevent disasters such as rock fall, collapse and so on. A set of monitoring equipment is developed to monitor MS activities and to locate the MS event by time...
There are many different factors that influence the safe production of coal mine such as equipment factor, environment factor and artificial factor etc. At current, many coal mines all over the world have built up harmoniously independent mutually monitoring and controlling sub-systems based on variety communicate channels and protocols. In this paper, a monitoring and controlling framework model...
In this article, we present a new approach to illustrate the production information of metal mine specified in object-oriented ideas for modeling more humanized and easily understanding system of digital mine. According to the present status of metal mine production in China and the functions of the whole process of mining, we use Unified Modeling Language (UML) to express the first abstract concept...
Based on GIS, especially on its spatial analysis function, a case study on the predicting and forecasting of the risk of coal floor water-inrush was practiced in the I-1 mining district in the 5# coal mine in Pingdingshan coal area in this article. The 5# mine of Pingdingshan coal area belongs to the typical Carboniferous-Permian coal mining area which were threaten seriously by the coal floor water-inrush,...
In view of the character of mining disaster and the limitation of traditional methods of earth surface deformation monitoring in western mining area, an attempt at adopting InSAR techniques in dynamic deformation monitoring in west mining area has been developed. This paper takes Shaanxi Province Binchang mining area as study area, processes the SAR image by differential interference, obtains the...
On the basis of engineering geological analysis method, the stability of a certain steel plant foundation in the underlying mined-out area is evaluated. In accordance with the loading concentration of steel plant structures and their importance, a classification is carried out and different grouting treatment measures are used accordingly. Afterwards, XB-160-foot vibrating wire strain gauges and XBHV-10-foot...
Taking industrial field test at Kelatongke Copper-Nickel Mine in Sinkiang, which uses the back-filling mining method based on environment reconstructed deep-hole introducing caving, as an engineering background, the three-dimensional mesh model of ore body excavation was constructed by using the MIDAS/GTS software, and then the model data were transformed into FLAC3D to build the numerical simulation...
Geology circumstance of closed environment is extremely complicated and there are many hidden trouble. In this paper, the signal sources of communication coal mine system are described in closed environment firstly, and then a kind of comprehensive information communication system based on the OFDM technology is presented. This system makes wire communication combined mutually with wireless communication...
Geologic hazard caused by open cast mine slide often have great influence on construction and production of mine engineering, and slope distortion is the most obviously and directly reason bring on geologic hazard. In consideration of complexity of open cast uranic slope rock mass, real-time analysis on instability of slope by GPS sectionalized monitoring will be adopted in the novel, and regard the...
