The embodiment of the invention discloses an adjustment method of multiple fan machine combined operation conditions at different locations in a mine. The adjustment method comprises the following steps of step 100, setting a sensor group used for parameter acquisition in a tunnel of a fan machine entrance, feeding back real-time data collected to a control system; step 200, using a three-dimensional simulation system of mine ventilation to optimize and calculate a ventilation network to simulate corresponding parameter values, and comparing the parameter values regarded as simulation analysis values with the data collected in the tunnel where fan machines are located; and Step 300, according to comparison results of operation condition parameters of the fan machines, adjusting operation frequency of fan machine motors one by one in a feeding back adjustment mode until the data collected by the sensor group are consistent with the system values to realize real-time combined regulation of multiple fan machines in the mine. According to the condition adjustment method, the fact that the combined operation conditions of the multiple fan machines in the different locations in the mine adapts to changes of total ventilation resistance, production scale and natural air pressure can be ensured, and requirements of air demand for mine safety production are met.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of mine ventilation condition adjustment, and in particular to a method for adjusting the joint operation conditions of multiple blowers at different locations in the mine. Background technique [0002] The mine fan is an important equipment to ensure the safe production of the mine. It is responsible for continuously conveying fresh air to the underground to supply personnel to breathe, dilute and discharge harmful gases and floating dust. Poor mine ventilation may lead to hazards such as personnel poisoning, gas explosion, and pneumoconiosis. Therefore, effective mine ventilation must be ensured. Generally, when selecting the fan model according to the mine air demand and mine ventilation resistance, it is necessary to consider the ventilation capacity of the fan during the easy period and difficult period of mine ventilation, that is, the operating condition of the fan is require...
