Analysis of Stress Distribution Characteristics of a 10 m Narrow Coal Pillar and Research on Channel Support Technology
Mines which currently facing resource depletion,adopting the method of reducing section coal pillars can effectively improve resource recovery rates and increase economic benefits.However,the stress changes in the surrounding rock caused by reducing section coal pillars also pose difficulties for roadway maintenance,support strengthening measures need to be targetedly researched.In response to this issue,referring to the actual conditions of the 10208 working face in Sucun Coal Mine,theoretical calculations and numerical simulation methods are used to study the stress,displacement,and plastic deformation situation happen in the roadway under the condition of setting a 10 m protective roadway coal pillar.By optimizing the support structure and improving the support strength,the stability of the roadway is ensured.
