    • Abstract
  • With MTSB815 rock electrohydraulic servo test system, we analyzed macroscopic properties and microscopic properties as well as permeability change for 15# Coal Seam in Zhaojia Partition of Yangquan No.5 Coal Mine, got several parameters, including roof and floor mechanics and coal adsorption constants, the initial velocity of the gas emission and firmness coefficient. Through theoretical analysis and experimental research laboratory, we obtained the diversification curve of stress-strain and stress - penetration about coal samples.
