Description

technical field

[0001] The invention relates to the technical field of industrial and mining safety monitoring, in particular to a device and method for monitoring the form of roof caving during initial discharge. Background technique

[0002] The basic characteristics of the comprehensive top-coal caving face are: compared with layered mining, the primary mining thickness is significantly increased, the caving height of the upper strata is significantly increased, and the range of rock movement affected by mining in front of the working face is also significantly increased. Monitoring the caving of the top coal and the roof behind the working face plays an important role in determining the process parameters such as the coal-drawing step distance, and selecting the appropriate coal-drawing step distance is crucial to improving the recovery rate and reducing the gangue content. In order to ensure the safe and efficient production of the working face, it is necessary to monit...
