Mine Water Hazard Monitoring And Warning Technology And Its Applications

The water disaster is a common form of mining disasters in the mining of mineral resources,,and more common in the small local mines.The water disaster causing great harm in the event of accidents, often with sudden and great harm not only affect production and also resulting in economic losses and prone to heavy casualties. Therefore, the most important coal mining geology mining task is to detect the distribution of small geology structures and water in the mining's region. The monitoring of coal mine water disaster early warning, the main investigation in two ways: geophysical and drilling. Drilling is the method of mechanical underground drilling, this method commonly used in the previous survey, it is costly, but also by the geological conditions, some cases are very demanding of technology. Is short for geophysical exploration geophysics. Primarily through the exploration of physical principles to the main study rocks of different densities, magnetic and other physical differences to study these differences by analyzing the corresponding geophysical data obtained, it concluded that detection of geological conditions within the region. It is more economical in terms of more drilling, and the relatively short period of time, prospects for its use more and more attention.In this paper the magnetic fluid detection technology has been applyied to the coal mine's undergroundwater hazards monitoring.Through the probe installed on the surface to the earth, the electromagnetic signal generated by the underground magnetic fluid inside the mining has been received. The signal transferred to the detection instrument from the detection cable. Through the analysis sofeware,we can extract the feature information from the detection signal. And the detection result was comprehensive alalysised and been concluded. The application shows that: underground magnetic fluid detection technology is an effective new method of mine water hazard control. The main research contents include the following:(1) Describes the classification of coal mines and features water hazards, analyze and study the formation of coal mine water disaster mode and mechanism of coal on the basis proposed method of prediction of water inflow budget.(2) Analysis of the traditional coal mine water disaster monitoring methods limitations, based on the coal mine water damage formation mechanism and characteristics, combined with underground magnetic fluid detection method of the basic principles of research and put forward the underground magnetic fluid detection in Mining conductivity fault. The old empty water tunnel and other underground karst fissures or the qualitative and quantitative detection method was been concluded.(3) Experimental demonstration. Watertown by Guizhou Province Mining (Group) Co., Ltd. of multiple coal mines, coal or other coal mining carried out practical experiments and applications, verify the reliability of the method proposed and the feasibility of detection.
