摘要
工作面通风方式和风量对采空区沼气涌出量的影响不容忽视,作者通过模型实验对这种影响进行了定量分析。本文介绍了实验方法、装置和结果,提出了关于风量以及常见的几种工作面通风方式对采空区沼气涌出量影响的修正方法和系数。
The Face ventilation systems and airflow quantity influence the goaf gas emission to a considerable extent. This influence is quantitatively analysed by means of model experiment. The design, apparatus and results of the experiment are shown. The modification of goaf gas emission under the conditions of several common face ventilation systems and airflow quantity is given.
