Disaster monitoring method for coal mine tunnel roof

Abstract

The invention relates to a disaster monitoring method for a coal mine tunnel roof. The method includes the steps that before monitoring, stability of tunnel surrounding rock is estimated, a surrounding rock risk type monitoring area is determined according to an estimation result of the stability of the surrounding rock, then a serious disaster area of the tunnel roof is determined, and monitoring instruments are only arranged in the serious disaster area of the tunnel roof and used for monitoring. According to the disaster monitoring method for the coal mine tunnel roof, only the serious disaster area of the tunnel roof is monitored, so that manpower, material resource and financial resource investment in monitoring by a coal mine enterprise is greatly saved, and production cost is reduced.

Description

technical field [0001] The invention relates to a coal mine roadway roof disaster monitoring method. Background technique [0002] According to statistics, in 2013, there were 604 accidents of various types in coal mines across the country, with 1,067 deaths, including 274 roof accidents and 325 deaths, accounting for 45.3% and 30.4% of the total, ranking first among all kinds of coal mine disasters. Disaster prevention and control is still the focus of coal mining enterprises and related scientific research institutes. [0003] Coal mine roadways are widely distributed and have been used for a long time, which is the most concentrated area of ​​roof disasters. Although the roadway support technology has been continuously improved in recent years, the stability of the roadway surrounding rock has been significantly improved, which has effectively reduced the occurrence of roadway roof disasters. However, with the deepening of coal mining, the depth of coal mining continues...

AI Technical Summary

Problems solved by technology

This kind of monitoring has played a certain role in the prevention of roof disasters, but because it only considers the differences in the properties of the surrounding rock and the roof and floor of the coal mine roadway, but does not consider this difference, the occurrence of roadway roof disasters is not random and occurs on a large scale. Monitoring consumes a lot of human, material and financial resources for coal mining enterprises, and the production cost increases sharply. At the same time, due to the single index of such monitoring, the reflection of the characteristics of the disaster itself is limited. The impact of disasters is limited

[0005] At present, there is no set of low-cost and effective coal mine roadway roof disaster monitoring methods
