Relations between Mine Ventilation Conditions and Gas-Emission Quantities Carried by Airflow

摘要

A common phenomenon frequently encountered in mine ventilation routine practices is that changes of mine ventilation conditions, i.e., changes of air pressure and air quantity, causes sequential variations of gas-emission quantity carried by underground airflow. The relations of these variations form an important part of the mixing kinetics of mine air and gas developed in recent years. These problems are discussed in detail in the paper.
