Risk identification and intelligent pre-control system and method for coal mine driving face

Abstract

The invention discloses a risk identification and intelligent pre-control system and method for a coal mine driving working face, a driving data fusion system is used for establishing a driving system database, processing various data according to a unified coding standard, and sending the processed data to a server for storage; the personnel behavior analysis intelligent identification system is used for judging the dangerous abnormal behavior of the personnel according to the shot limb movement track of the personnel and performing early warning; the equipment information integration and remote online diagnosis system is used for judging whether the digging and anchoring all-in-one machine and the ventilator have faults or not according to the obtained equipment operation parameters and performing early warning; the security situation analysis and early warning system is used for analyzing the change trend according to the data acquired each time, then performing time sequence modeling on various monitoring data, judging whether a trend of occurrence of a major risk exists or not, and performing early warning; and the collaborative management and control and intelligent scheduling system is used for controlling the operation states of the digging and anchoring all-in-one machine and the ventilator when the three systems give out early warning, and transmitting early warning information to all underground personnel.

Description

technical field [0001] The invention relates to the technical field of mine safety, in particular to a system and method for risk identification and intelligent pre-control of a coal mine excavation face. Background technique [0002] Roadway excavation is an early and basic project for coal mining. Focusing on the two goals of safe and efficient excavation, the development of intelligent technology and equipment for safe and efficient excavation in coal mines has important application and promotion value. At present, the underground intelligent safety risk identification and intelligent pre-control system is mainly in the testing stage. The Chinese invention patent provides a method, device and system for detecting violations of roadheader personnel (CN202011540237.0), which realizes automatic identification of roadheader personnel. Illegal and out-of-bounds operations, timely detection and alarm; China's invention patent provides a 5G+ smart mine control system and method ...

AI Technical Summary

Problems solved by technology

From the above, it can be seen that the existing intelligent identification system of the excavation face has a single function, and each system is independently operated and analyzed, and the unified risk identification and intelligent pre-control of man-machine-environment in the excavation face has not been formed, and The data structure of the excavation face is complex, and there is a lack of a unified multi-source heterogeneous data processing model

Excavation equipment, personnel, and environmental data are isolated and scattered, and there is a lack of a unified system platform to predict various abnormal situations in the excavation process in advance and to perceive the overall safety situation of the coal mine in real time, resulting in slow response speed when accidents occur, and low efficiency of intelligent analysis and control linkage

The interaction between the staff and information in the mine is poor, and the alarm and abnormal event processing process cannot be completed in time, which seriously affects the efficiency of coal safety production
