The rapid development of China coal mine safety management information play an important role on improving mine safety standards, however, there exist some problems such as cannot be a comprehensive system of monitoring, evaluation and analysis of safety, forecasting of security trends, etc. Papers have researched based on this problem, carrying out research on an analysis and collection of security...
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...
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,...
A growing nμmber of studies in recent years have focused on how to use remote sensing for dynamic monitoring and effective evaluation of vegetation conditions and vegetation growing environment in mining areas, which will provide a scientific basis for making policies for controlling the environment in mining areas. In this paper, airborne hypersectral remote sensing data - HyMap images in the Mount...
A novel alarming assessment model of coalmine gas is presented in this paper. Based on the information fusion technique of multi-sensor, we introduce the thought of variable fuzzy set to assess complicated and risk coalmine gas. Through information fusion we can get more effective and reliable data about coalmine gas. The method for variable fuzzy set theory can reasonable identify the relative membership...
