The invention discloses a mobile electromagnetic radiation positioning detection and early-warning dynamic mine disaster method. An electromagnetic signal acquisition device, a signal transmission device and a terminal early-warning device are employed by the method. The electromagnetic signal acquisition device is integrated with signal acquisition and positioning modules; and a worker is able tocarry the device to collect an electromagnetic signal at the location in real time and identify the location information. Relevant electromagnetic signals and positioning information are transmittedto a multifunctional confined space communication system capable of realizing high-precision positioning and wireless access capabilities wirelessly in real time; the system carries out fiber transmission of related information; the process information is sent to a terminal integrated analysis and early-warning platform finally; the terminal platform carries out calculation based on the electromagnetic signal and position information to obtain a mine (mining area) electromagnetic radiation distribution cloud chart and time-sequence changing curves of all measuring points; and a dangerous areais determined by the cloud chart and real-time early warning is carried out based on the time-sequence changing curve.
Description
technical field [0001] The invention relates to a method for mobile electromagnetic radiation positioning detection and early warning of coal-rock dynamic disasters, belonging to the field of coal-rock dynamic disaster monitoring and early warning. Background technique [0002] my country's coal mining conditions are complex, and coal-rock dynamic disasters are one of the main disasters in coal mines. As the mining depth continues to increase, the frequency, intensity, and degree of damage of coal-rock dynamic disasters are on the rise, and the number of occurrences and casualties are also on the rise. The monitoring and early warning of coal-rock dynamic disasters mainly include static index method and geophysical method. The amount of information obtained by the static index method is limited and the accuracy is low, while the geophysical method can realize real-time, dynamic and continuous monitoring. [0003] Electromagnetic radiation generated by rock deformation and ...
