Among the major and major accidents in our country, most of them Heavy gas accident, casualties caused by gas accident ...
  • Deformation early warning device for coal mine support and its implementation method and process
    The invention relates to the safety early warning of underground coal mine support, and specifically relates to a coal mine support deformation early warning device and an implementation method thereof. During the mining process, the roof will be deformed to varying degrees due to pressure changes. Generally, cracks appear along the joints of the roof and are accompanied by delamination. If the protection is improper or the quality of the support is not good at this time, the pressure continues to increase, and the deformation of the rock exceeds the limit, there will be fractures, falls, chipping or partial roofing. ...
  • The invention relates to the classification and determination of rockburst in coal mines, and in particular to a method for classification and determination of rockburst based on the subject of energy release. In recent years, with the increase of coal mining intensity and mining depth, factors such as deep high ground stress and complex geological conditions have caused the frequent occurrence of rockburst in China's coal mines, which seriously affects the safe mining of coal mines. Aiming at the problem of rockburst, the current research mainly includes three aspects of the mechanism of rockburst occurrence, monitoring and prevention, among which ...
