Abstract:
Based on the research background of the 2309 transportation roadway in Malan Mine, and the difficulty in supporting the 2309 transportation roadway in a multi fractured coal body, a high-efficiency anchoring support technology for multi fractured coal body roadway is proposed.UDEC is used to simulate the displacement and deformation of the surrounding rock in the working face under different mining stresses, and the design parameters of the anchoring mesh and cable support for the surrounding rock in the 2309 transportation roadway are provided.The on-site practice results show that under the action of strengthening control and efficient anchoring support technology, the deformation of the two sides and roof of the roadway is small with good support effect, and the deformation of the multi crack coal body roadway can be effectively controlled.The research results have certain reference for solving the support problem of roadway under similar geological conditions.
