Abstract

Through the study of harmful gas treatment technology in small pillar side gob in the process of tunneling and stopping of small pillar driving face,the influence of gob on small pillar driving roadway is achieved under the condition of deep well and high ground pressure.The technical system that can effectively control the impact of harmful gas in gob on tunneling and stopping process of small pillar driving face is put forward,which ensures the production safety.
- small pillar roadway driving,
- gob,
- gas drainage,
- nitrogen injection,
- replacement,
- gas control
