Abstract

The invention provides a dynamic mine disaster integral early warning method and device and belongs to the field of coal mining dynamic disaster prediction evaluation. The coal and rock stress, coal and rock noise, coal and rock electric field, coal and rock temperature, coal body desorption gas sensor are integrated to form an integral probe, the integral probe and a dynamic disaster analyzer form a dynamic mine disaster early warning device, the device can predict the type and the class of dynamic disasters, meanwhile can evaluate the danger relieving effect of control measures and achieve the purpose of preventing dynamic mine disasters. The integral early warning device is low in energy consumption, small in volume, simple in structure, strong in anti-interference performance and has great significance on reduction of safety accidents caused by the dynamic mine disasters and improvement of the safety performance of mining roadways.

Description

technical field [0001] The invention belongs to the field of prediction and evaluation of coal mining dynamic disasters, and in particular relates to an integrated early warning method and device for mine dynamic disasters. Background technique [0002] Coal and gas outburst and rock burst are the most serious dynamic disasters encountered in coal mine production. When coal and gas outburst occurs, the underground coal body throws a large amount of coal and gas into the roadway or stope; when rock burst occurs, the underground roadway or mining face is destroyed rapidly, and the damage time is only a few seconds to ten seconds , the damage range can reach hundreds of meters, and the projected coal can reach tens of thousands of tons. As of the end of 2012, there were 1,141 coal and gas outburst mines and 142 rock burst mines in my country. With the increase of energy demand and mining intensity in my country, most mines in China will enter the deep mining stage in the next ...
