Analysis of disaster mechanism and countermeasures for endangered pipeline security in mining subsidence areas

Mining-subsidence is one of the important geological disasters endangering the security of pipeline. Through the discussion of endangered pipeline security for surface movement and distortion by mining,the harmful characteristics of pipeline by mining-subsidence are analyzed. On the basis of the analysis of surface movement and roof distortion in the mine region,the disaster mechanism and its influencing factors for endangered pipeline security are discussed. The associated treatment measures ar...
