- W1769526051 abstract "Taking the 12108 working face 3-1 coal seam in Lijiahao coal mine as the engineering background, comprehensively applying roof borehole observation, multi-base point displacement monitoring, measuring the range of loose damage of surrounding rock and other measurements to get in-depth knowledge of the characteristics of surrounding rock damage of roadway, on this basis, put forward four kinds of optimization of roadway support scheme. Through applying the calculation method of numerical simulation and taking the economic efficiency into account, provide the optimized support scheme for the roadway which is affected by first mining activity and second mining activity respectively. Provide the basis for support parameter choosing in shallow buried thin bedrock roadway. Keyword-shallow buried; mining roadway; support" @default.
