Feasibility analysis of coal mining under gas gathering pipelines and calculation of mining impact

In response to the issue of four gas gathering branch lines affecting the development layout and efficient and safe mining of a certain coal mine in the western part of Yulin, an analysis is conducted on the optional mining methods for pressurized coal mining under pressure. The calculation of mining impact under different working conditions is conducted, and it is found that under the premise that full thickness mining cannot meet the safe operation of the gas gathering pipeline, the requirement for safe operation of the pipeline can be achieved by using limited thickness mining (3.4 m) within the protected coal pillar range of the pipeline. It can provide reference for coal mining under similar mining conditions.
