Abstract

The invention discloses an intelligent coal mining working face gas prediction and equipment linkage safety guarantee system and method. The system comprises a working face key procedure equipment automatic regulation and control system and a working face multi-source gas emission dynamic prediction system. The working face key procedure equipment automatic regulation and control system is composed of a coal mining machine regulation and control unit, a coal caving support regulation and control unit, a conveyor regulation and control unit and a ventilation facility regulation and control unit. The working face multi-source gas emission dynamic prediction system is divided into a basic parameter input module, an equipment operation parameter input module, a gas emission prediction and parameter calculation module and a parameter calculation result output module. According to the method corresponding to the system, the working face gas emission amount can be predicted according to the equipment operation state parameters collected by the system and the return air flow gas emission actual measurement value, the equipment reasonable operation state parameters are calculated, and it isguaranteed that working face gas emission is in the expected stable state. The system and the method can be widely applied to intelligent coal mining working face gas emission control and gas prevention and control work.

Description

technical field

[0001] The invention belongs to the field of mine gas prevention and control, and in particular relates to an intelligent coal mining face gas prediction and equipment linkage safety guarantee system and method. Background technique

[0002] With the rapid development of automation and information technology, more and more mines have realized the intelligentization of coal mining, which has greatly reduced the number of operators in the coal mining face, reduced the labor force, improved work efficiency, and to a certain extent Reduced the occurrence of casualty accidents. However, at present, most of the supporting security systems for intelligent working faces are still in vacancies or in the development stage. Although the intelligentization of coal mining can reduce personnel injuries, it cannot fundamentally eliminate various accidents, especially the hidden dangers of gas accidents. Losses and social impacts still cannot be ignored, and seriously restr...
