▎ 摘　　要

NOVELTY - The system has a data analysis and storage device (1) that is provided for receiving monitoring data of an electronic signal terminal server and a distance detection device (10). A filtering unit (2) is set to filter the monitoring data and the distance detecting device. The electronic signal terminals are provided with a graphene carbon crystal electronic release probe (7) and a graphene carbon crystal electronic receiving probe (11). The graphene carbon crystals electronic release probes are arranged in multiple lanes. A mode selection unit (3) is arranged on the electronic terminal server. The mode selecting unit is set to select and determine a monitoring parameter according to mining conditions. The distance detection device is set to measure depth of coal layers, coal thickness and coal inclination angle. The pre-warning device is set to send a pre-warning signal according to the feedback result of the data analysis and storage device. USE - Coal bed bottom plate variable parameter water inrush passage pre-warning system for use in mining engineering field. ADVANTAGE - The system accurately judges the water burst risk and real-time early warning, and provides scientific and effective judging standard for coal-bed water-preventing and water safety preventing production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a coal bed bottom plate variable parameter water inrush risk judging method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the coal bed bottom plate variable parameter water inrush passage pre-warning system.
