Abstract
The disclosure provides a real-time monitoring system and a real-time monitoring method for coal mine roof fractures during a roadway tunneling process, where the monitoring system includes a roadway model building module for building a three-dimensional model of a roadway; a roof monitoring module for obtaining roof fracture development data in real time; a fracture analysis module for obtaining a development pattern of roof fractures according to the three-dimensional model of the roadway and the roof fracture development data; a fracture formation prediction module for judging a fracture formation time according to the development pattern of the roof fractures; and an early warning processing module for early warning according to the fracture formation time.
