Abstract: In order to solve the force and slip on pipe laying which laid in large slope roadway, the force model on pipe laying is established and simplified, and the force analysis and calculation method are discussed. Then the force and slip on pipe laying are analyzed, which laid in certain roadway with varied slope at Liudian mine; The control measures on pipe slide are proposed, the reliability of pipe installation is improved.

Key words: uphill and downhill roadway, chilled water pipe, pipe laying, force analysis
