摘要
以平顶山煤业（集团）公司十矿２０１３０综采工作面为例，研究了Ｕ型通风工作面风流流动与采空区瓦斯涌出之间的关系及采空区瓦斯涌出治理原则．提出了前进式预埋管法抽放采空区瓦斯的技术措施，结果表明，该技术措施对于解决Ｕ型通风工作面采空区上隅角瓦斯积聚问题具有重要作用．
The principle of control of gas emitted from the minedout area and the relationship between airflow and methane emission in a face with U type of ventilation system are studied in No20130 fully mechanized coal face in No10 Mine of Pingdingshan Coal Mining (Group) Incorporation. A technical measure of methane drainage from the minedout area by a preburied advancing pipe is proposed. It is found that this method is very important in diluting the gas accumulated in the upper corner of the mined out area in a face with a U type ventilation system.
