Analysis of the Manifestation Law of Mine Pressure in the Reserved Roadway of Fully Mechanized Mining Face
Taking the actual development and mining situation of the first working face of the Great Wall No.3 Mine as an example,the stress distribution during the actual mining period of the working face and the movement of the roof and floor of the retained roadway were mainly monitored using on-site monitoring methods.The characteristics of the mining pressure manifestation and response of the retained roadway affected by mining were analyzed.The monitoring and analysis results are expected to provide a better understanding of the mine pressure response law between the mine and the remaining roadway of the working face,in order to provide favorable theoretical references and practical engineering value for similar engineering geological conditions such as mining in the working face.
