A gas concentration control system for fully mechanized coal mining face based on big data

Abstract

The invention provides a large data-based gas concentration control system for fully-mechanized mining faces in coal mines, which belongs to the technical field of control systems and aims to solve the problem of slow reaction speed, inflexibility, high energy consumption and low safety of gas concentration control in underground fully-mechanized mining faces. including cloud server and detection terminal; cloud server includes terminal management module, coal mine big data module, data matching module, data processing module, comparison module, temporary storage module, control module and communication module; system among the present invention can Realize the intelligent linkage control of the gas concentration of the fully mechanized mining face under the big data; through the setting of multiple detection terminals, the sub-node equipment power regulation of the fully mechanized mining face is carried out, reducing the overall energy consumption of centralized ventilation and spraying, and saving energy; The single-point equipment power control makes the response speed more flexible and rapid; the single-point early warning, the overall response provides sufficient reaction time for fully-mechanized mining face operators to ensure the safety of workers.

Description

technical field [0001] The invention relates to the technical field of control systems, in particular to a large data-based gas concentration control system for fully mechanized mining faces in coal mines. Background technique [0002] Underground coal mines, "one access and three defenses" directly affect the safety of operations, specifically ventilation, dust prevention, gas prevention and fire prevention. Ventilation is critical to safe operation in coal mines. Because the coal seam contains gas, the air gas concentration must be strictly controlled during the mining process, and safety accidents caused by excessive underground gas concentration are common every year. At present, the use of large-scale ventilation equipment to reduce the gas concentration is a common treatment method. Ventilation equipment is used to ventilate the fully mechanized mining face as a whole. The operating power of the equipment is usually fixed, and it cannot , adaptively adjust the power ...

Problems solved by technology

At present, the use of large-scale ventilation equipment to reduce the gas concentration is a common treatment method. Ventilation equipment is used to ventilate the fully mechanized mining face as a whole. The operating power of the equipment is usually fixed, and it cannot , adaptively adjust the power of the equipment, the operation control of the equipment is inflexible, resulting in a lot of energy waste; and usually the underground ventilation equipment, spray equipment and detection terminals are independent of each other, and cannot be linked and adjusted, and the reaction speed is slow when encountering emergencies , the use is not flexible; when the gas is protruding during operation, the mining and transportation equipment cannot be stopped in time, and a large amount of heat is generated during the operation of the equipment, which is easy to cause a gas explosion, threatening the life and property safety of the workers.
