摘要
瓦斯治理是煤矿开采过程中一项重要内容,沿空留巷Y型通风与传统的U型通风和U+L型通风相比,前者能够提高矿井通风量,而且能够有效消除以往工程量大、掘进速度等各种煤矿开采作业造成不良影响的问题。下面,在分析采煤工作面出现瓦斯的原因基础上,依据工程实例,对沿空留巷Y型通风采面瓦斯综合治理方法进行研究,希望文中内容对相关工作人员,以及煤矿行业发展都能够有所帮助。
Gas control is an important content in the process of coal mining.Compared with the traditional U-type ventilation and U+L-type ventilation,the Y-type ventilation of gob side entry retaining can improve the mine ventilation,and can effectively eliminate the adverse effects caused by various coal mining operations such as large quantities of projects and driving speed in the past.Next,based on the analysis of the causes of gas in the coal mining face,and according to the engineering examples,the comprehensive gas control method of Y-type ventilation mining face with gob side entry reserved is studied.It is hoped that the content of this paper can help the relevant staff and the development of the coal mining industry.
