掘进工作面氡气来源分析和关键治理技术研究

双马煤矿在缓坡副斜井掘进工作面掘进过程中局部地段出现氡气,为了保护作业人员的身体健康保障矿井安全,基于分析研究掘进工作面特殊底层氡气来源、运移规律,以理论指导现场,总结出喷、涂、增、降、检、撤、护七字关键治理技术,从而实现对氡气地质带的有效治理和管控,保障了掘进工作面的安全生产。

Study on the Source of Radon Gas and Key Governance Techniques in Tunneling Face

Radon gas occurs in some parts of Shuangma Coal Mine in the process of driving in tunneling face of sub-inclined shaft with gentle slope,which threatens the safety of underground workers. In order to protect the workers’ health and ensure the safety of the mine,the source and migration of radon gas from the special ground floor of the tunneling face are analyzed. The key governing technologies are put forward from the seven aspects of spraying,painting,increasing,lowering,inspecting,withdrawing and protecting,so as to realize the effective management and control of radon geological zone and ensure the safe production of tunneling face.
