Study on the Influence of the Cage Lifting Piston Effect in Main Intake Shafts on Air Flow in Transportation Lanes

Round 1

Reviewer 1 Report

Significant finding need to be add in Abstract Section

Introduction can be simplify. The last paragraph required to highlight the objective of study

The correlation between section of discussion can be improved

The conclusion section need to be tightened in order the reveal the study

Reviewer 2 Report

This manuscript investigated the effect of piston effect on the airflow field in the transport lane based on the SST k-ω turbulence model and the dynamic meshing through numerical simulations, which provides some useful information for the safe and stable operation of mine ventilation systems. The work is interesting. Therefore, I recommend the manuscript for publication after addressing the following minor comments:

(1) There are some typos throughout the manuscript which need careful editing. 

(2) In the second paragraph of Introduction,  it is recommend that the authors list some real accidents to illustrate the severe consequences of piston effects.

(3) Adding a paragraph at the end of Introduction is suggested to illustrate the main work of each section.

(4) The authors should replace "grid" with "mesh" or "meshing" throughout the manuscript.

(5) Please add relative contents describing the model’s boundary condition in Section 2.3. 

(6) The authors can add a discussion to compare other researchers' research on piston effect in a single roadway flow field with the conclusions considering the connection between shaft and transport lane in this manuscript.

Round 2

Reviewer 1 Report

The conclusion needs to be revised. Make it short and firm.
