AI Technical Summary

Technical Problem

In existing technologies, ground pressure prevention assessment equipment is unable to fully and deeply reveal the true situation of rockbursts under complex geological conditions, resulting in insufficient accuracy and timeliness of early warnings and failing to provide reliable safety guarantees.

Method used

The coal mine rockburst prevention and assessment device, which combines multiple monitoring methods, includes a stress sensing unit, an electromagnetic radiation detector, and a microseismic sensing unit. Together with the drill cuttings assembly, it enables multi-dimensional monitoring of the stress state, electromagnetic radiation, and vibration of the coal and rock mass. The drill cuttings assembly is used to collect boreholes and drill cuttings for comprehensive assessment.

Benefits of technology

It significantly improves monitoring accuracy and early warning timeliness, accurately capturing subtle details of ground pressure changes and providing a scientific basis for prevention and control measures.

Abstract

The present application relates to the technical field of coal mine safety and discloses a rock burst prevention and control evaluation device and method for coal mines, which comprises a frame assembly, a monitoring assembly and a drilling cuttings assembly. The monitoring assembly is arranged on the frame assembly. The monitoring assembly comprises a control host and a sensing part. The sensing part comprises a stress sensing unit, an electromagnetic radiation detector and a microseismic sensing unit. The stress sensing unit is used for monitoring the stress state of a coal rock mass. The electromagnetic radiation detector is used for monitoring the electromagnetic radiation during coal mining. The microseismic sensing unit is used for monitoring the vibration during coal mining. The stress sensing unit, the electromagnetic radiation detector and the microseismic sensing unit are electrically connected to the control host. The drilling cuttings assembly is arranged on the frame assembly. The drilling cuttings assembly is used for drilling a hole in a coal seam and collecting drilling cuttings. Through the cooperative work of the monitoring assembly and the drilling cuttings assembly, the problem that a single drilling cuttings method in the prior art cannot comprehensively reveal the real ground pressure condition under complex geological conditions is solved.
