Reviewer 2 Report
The authors studied the influence of yield pillar on the stability of Coal Mine roadway mainly by numerical simulation. The work is comprehensive. The following suggestions are provided to purify the paper.
1) Some language issues, for example, after the formula, "Where" should be "where" without text-indentation.
2) In the description of the model, the authors should add the information around the elements being used, the boundary conditions, and the algorithm being chosen.
3) In Table 1, what are the abbreviate symbols, such as "K", "G"...
4) Where did the data in Table 1 come from? Reference should be provided.
5) The units for the stress and displacement should be provided, such as in Figure 8, Figure 12
6) How did the authors determine the tensile failure region in Figure 9? Have you considered the plastic properties?
7) Some discussions about the validation of the simulation model or results are suggested to provide.
8) Please unify the format of the references.
