摘要
通过对小煤柱掘巷工作面掘进和回采过程中小煤柱侧采空区有害气体的治理技术的研究,得出深井高地压条件下采空区对小煤柱掘进巷道的影响,提出了有效治理采空区有害气体对小煤柱掘进工作面掘进、回采过程影响的技术体系,确保了安全生产。
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.
