摘要:Abstract(#br)The important role of ventilation in underground mines is to guarantee safety and proper environmental conditions in all accessible areas of a mine by applying national mining laws and regulations. A mining ventilation network changes all the time as a result of mov...

摘要:Abstract(#br)This paper presents an algorithm for calculating the stability of air flows in mine ventilation networks in case of random variations of air resistance. The analysis of the stability of air flows in the algorithm is based on two proposed criteria, which are calculate...

摘要:Abstract(#br)To analyze the airflow stabilization induced by gas accumulations in a mine ventilation network, a transient model for airflow caused by gas accumulations is presented. The Runge Kutta method is selected to solve this model. To quantify the average gas density in the...

摘要:Abstract The present paper discusses determining diagonal branches in a mine ventilation network by means of a method based on the relationship A⊗ PT(k, l) = M, which states that the nodal-branch incidence matrix A, modulo-2 multiplied by the transposed path matrix...

摘要:... Optimizing urban ventilation environment could relieve these environmental problems. In this study, an Urban Ventilation Network Model (UVNM) was developed to explore the impact of urban morphology and building height on the urban ventilation condition. The study calculated t...

摘要:Abstract(#br)Application of 1D Transient Flow Model to a network analysis finds that the fluids in two branches (which are connected in parallel and contain no drive source) may no longer flow in a same direction while the network flow state changes from being steady into be...

摘要:Abstract(#br)Tracer gases are an effective method for assessing mine ventilation systems, especially when other techniques are impractical. Based on previously completed laboratory and field experiments, this paper discusses some common and challenging issues encountered when usi...

摘要:... Consequently, it becomes necessary to adapt the ventilation network of a mine to direct airflow into newly-opened districts. For economic reasons, opening new fields is often achieved via underground workings. Length of primary intake and return routes increases and also incr...
