Abstract

Roof weighting in fully mechanized mining face is a crucial factor affecting safety and efficiency in coal mine production. Accurately predicting the timing and intensity of roof weighting is the key to achieving scientific support. By analyzing geological conditions, coal seam occurrence characteristics, and mining process parameters, a roof weighting prediction model is constructed, which is further revised with on-site monitoring data to improve prediction accuracy. In terms of support optimization, numerical simulation and mechanical analysis methods are comprehensively applied to optimize the design of support parameters, support types, and arrangement methods, ensuring the stability and adaptability of the support system during roof weighting. This method can effectively reduce the risk of roof accidents, extend the service life of supports, and improve the production efficiency of the working face, providing theoretical support and technical reference for the safe and efficient production of fully mechanized mining faces.
