Research of Shed-Cable Supporting Technology & Regularity of Minig Roadway Pressure in Three-Soft Seam

Abstract:

According the analysis of the test in Baiping coal mine, obtain the characteristics of deformation and failure in three-soft seam roadway; get the exact data of roadways main deformation parameters and make sure the main deformation region division. By using the theory of equilibrium arch, analyze and finally determine bolt (cable) support attached with U shaped tents parameters. On-site tests show that this kind of support scheme can effectively control the deformation in three-soft seam roadway.
