摘要
为治理瓦斯涌出异常区域,通过对万年矿13290工作面现场调查,资料分析,根据刮板输送机槽、运料巷、切眼的不同条件分别制定方案。刮板输送机槽利用临近采空区预抽煤层瓦斯;运料巷利用超前钻孔边掘边抽;切眼利用刮板输送机槽施工钻孔泄压、预抽瓦斯。通过对瓦斯异常区的综合治理,缓解了矿井地区衔接紧张的被动局面,为今后处理类似问题提供了参考。
In order to control gas emission abnormal area,through field investigation and data analysis to 13290 working face in Wannian Mine,according to scraper conveyor trough,haul lane and cut hole different conditions,plans were made respectively. Scraper conveyor trough used adjacent goaf drainage of coal seam gas; Haul lane used advanced drilling extraction dug; Cut used the scraper conveyor trough construction drilling relief,pre-pumping gas. The comprehensive treatment of gas anomalies,alleviated the mine region join the passive situation of tension,provided reference for dealing with similar problems in future.
