Mechanical Properties and Bursting Liability Experimental Research of Roof in East Mine of Kouzi

摘要

In order to understand bursting liability and related mechanical properties of roof mudstone in east mine of Kouzi, SANS material mechanics testing machine is utilized as power equipment, bursting liability and related mechanical properties of roof mudstone has been tested, and MATLAB is exploited to analyze mathematical analysis for results. Experimental results showed that roof rock with strong bursting liability in east mine of Kouzi, its relevant safety should be improved; we can adopt the way of water injection into roof strata to change its mechanical properties, the purpose of safe mining is achieved. Research conclusion provides theoretical basis for safety mining in deep Yongchuan mine in east of Kouzi.
