Coal mine gas extraction parameter automatic regulating and controlling system and coal mine gas extraction parameter automatic regulating and controlling method

Abstract

The invention discloses a coal mine gas extraction parameter automatic regulating and controlling system and a coal mine gas extraction parameter automatic regulating and controlling method. The regulating and controlling system comprises a data collecting system, a data processing system, a regulating and controlling system and a warning system, wherein the data collecting system is in charge of collecting and displaying monitoring data such as the gas concentration, the flow rate and the extraction negative pressure in a gas extraction pipeline; the data processing system is in charge of receiving and storing the monitoring data, analyzing the data and providing a response signal for the regulating and controlling system and the warning system; the regulating and controlling system is in charge of regulating the operation parameters of a gas extraction pump arranged on the extraction pipeline according to the received response signal; and the warning system is used for warning the unreasonable extraction parameters and extraction states in a sound and light mode according to the received response signal. The operation state parameters of the extraction pump are changed in a mode of automatically regulating the extraction pump; the effects of effectively monitoring the pipeline gas extraction parameter and automatically regulating the work state of the extraction pump are achieved; the warning is achieved on the defective extraction condition; and the gas extraction efficiency is improved.

Description

technical field [0001] The invention relates to the field of mine mining, in particular to an automatic control system and method for mine gas drainage parameters. Background technique [0002] The mine gas problem is the main problem restricting the safe production of high gas mines. At present, mine gas control adopts gas drainage method, and the gas in the coal seam and goaf is brought to the ground through the drainage pipeline. Gas drainage is the fundamental strategy to prevent gas accidents, and efforts must be made to achieve drainage standards. [0003] The main factors affecting the efficiency of gas drainage include the gas content in the area that can be extracted, the gas permeability coefficient of the coal seam, the sealing process of the borehole, the drainage design, and the equipment capacity. The existing gas drainage system requires manual monitoring and control of each drainage parameter, the drainage efficiency is not high, and the degree of work autom...
