摘要
唐山矿业公司T1392综放工作面瓦斯涌出异常,严重威胁着矿井的安全生产。通过对瓦斯异常涌出情况进行分析,找出了造成瓦斯异常涌出的主要因素:大气压力变化、采区阻力分布状况、相关系统等,采取了加强工作面放煤、泄瓦斯道埋管抽放、相关系统调压泄放等有针对性的治理措施,杜绝了工作面瓦斯超限的事故。
The safety mining of Tangshan Branch Mining Co. is severely affected due to abnormal gas burst at the fully-mechanized top-coal caving face T1392. Analysis shows that the abnormal gas emission is attributed to a series of factors, such as variation of atmospheric pressure, distribution of ventilation resistance, in mining district and the conditions of related systems. Through taking comprehensive control measures including timely draw-off of coal from face, laying drainage pipes gas discharge way and regulation of ventilation pressure in other roadways. The phenomenon of gas over-limit at face is thoroughly eliminated.
