The optimal air distribution in a ventilation system as the condition of reducing mine ventilation costs

摘要

The advantages of optimisation of air distribution in the ventilation system of a copper mine are presented. Based on simulated calculations the regulation of air distribution was performed. This regulation is optimal with respect to electricity consumption and, as a consequence, optimizes the influence of energetic factor on the cost of ventilating excavations. The negative airflow regulators were used to control air distribution. In order to ensure proper ventilation intensity in excavations and dog headings, such regulation of air flow was adopted which ensures the lowest level of energy consumption by installing underground fans in the specific ventilation side branches.
