The Intelligent Control System of the Freezing Station in Coal Mine Freezing Shaft Sinking
In order to address the issue of low degree of automation and huge waste of electric energy of the equipment in drilling engineering freezing station which adopts the freezing method of coal mine, we need to design an intelligent control system to control both the brine pump and double stage ammonia screw compressor. According to the actual cooling need in freezing project, this new system is a...
متن کاملApplication of cut set method to reliability evaluation of mine ventilation networks
Providing a fresh and cool airflow in underground mines is one of the main concerns during mining. Destruction of support systems, the presence of undesirable objects in the airway and distortion of airflow are the parameters involved that would result in pressure loss, which would affect the ventilation network. There are a lot of research works about the ventilation network planning that cons...

SOURCES Original data from our pediatric intensive care unit and animal research laboratory. Relevant articles included in the MEDLINE electronic database during the last 10 years. Also included...
متن کاملAdvances in neonatal conventional ventilation.
Despite the implementation of several alternative strategies for management of respiratory failure in neonates, such as extracorporeal membrane oxygenation, high frequency ventilation, and nitric oxide, conventional assisted ventilation remains the mainstay of treatment. This has traditionally been accomplished by time cycled, pressure limited ventilators over the past three decades primarily b...
متن کاملConventional mechanical ventilation
INTRODUCTION — Conventional mechanical ventilation refers to the delivery of full or partial ventilatory support by a volume-cycled mechanical ventilator or by pressure support. It also can include the maintenance of positive airway pressure at the end of exhalation, ie, positive end-expiratory pressure (PEEP) [1]. (See "Physiologic and pathophysiologic consequences of positive pressure ventila...
