    • Abstract
  • During the mining stage of the roadway in Bulianta Coal Mine, due to the influence of many times of mining, the roadway has the problem of wall spalling which affects the normal production of the coal mine. In order to control the deformation of surrounding rock roadway and save support cost, a series of field tests and numerical simulation analysis were carried out in the mining roadway of Bulianta Coal Mine, such as borehole peeping, loosening zone testing, etc. The magnitude and direction distribution of main stress of surrounding rock under the influence of different mining action and the failure characteristics of surrounding rock were studied. The supporting parameters are changed. The engineering practice shows that the optimized support parameters can effectively control the deformation of surrounding rock, save the support cost and improve the tunneling efficiency.
