Detection method for coal mine rock burst

Abstract

The invention relates to a detection method for the coal mine rock burst. The detection method specifically comprises the steps of coal mine rock burst early warning detection, coal mine rock burst danger area classification and coal mine rock burst division. A mine vibration detector and a micro-earthquake detection system are installed in a mine in advance to carry out early warning detection on the rock burst in the coal mine; then through coal mine rock burst danger area classification, danger areas can be accurately detected; finally coal mine rock burst division is carried out, and therefore energy-gathered rock stratums in mining areas can be cut, energy can be fully released in the explosion process, and the mining safety can be improved. According to the invention, early warning, detection and division and danger treatment are carried out on the coal mine rock burst, and therefore coal mining is more accurate and safer.

Description

technical field [0001] The invention relates to a detection method, in particular to a coal mine rock burst detection method. Background technique [0002] The coal industry is the basic industry of our country. Its healthy, stable and sustainable development is a major issue related to the national energy security. However, the number of mine wells and the total number of rock bursts did not decrease. Especially in the eastern mines, there are not a few mines with a depth of 1,000 meters, and there will be more and more mines. From the perspective of coal mining practice, the number of rock burst mines will gradually increase, and rock burst disasters will become more serious. If the pressure in the coal and rock mass exceeds the strength limit of the coal and rock mass, the energy accumulated in the coal and rock mass around the roadway or stope will be released suddenly, and an explosive accident will occur in the roadway. Sound is a kind of mine earthquake induced by m...

AI Technical Summary

Problems solved by technology

The existing method is to infer whether there is a risk of impact based on the magnitude of the stress, but there is no direct relationship between the magnitude of the stress and the risk of impact, so this method has great limitations and low accuracy

At the same time, the existing methods lack early warning means, and cannot detect problems in time, resulting in serious losses.
