Construction and Application of an Intelligent Roof Stability Evaluation System for the Roof-Cutting Non-Pillar Mining Method

In order to sustainably use coal resources and reduce mine accidents, the stability evaluation of roadway roofs is particularly important. The existing methods roof control application are greatly disjointed, relationship between early warning ignored, an intelligent calculation system lacking. Based on successful roof-cutting non-pillar mining method in various engineering geology conditions, system, mobile computing research carried out. An index for established, including rock integrity roof-surrounding displacement. A comprehensive grades proposed based coupling grading criteria improved analytic hierarchy process (AHP) weight assignment. handheld platform evaluation, hazard zone, suggestion developed. results have been applied Hecaogou with good outcomes. This will provide economical effective approach achieving sustainable resources.
