The invention provides a coal mining monitoring method and device and computer equipment. The method comprises the steps that a micro-seismic signal corresponding to a first monitoring area is monitored, and the micro-seismic signal comprises the seismic moment of each micro-seismic source in the first monitoring area and the observation arrival time and the calculation arrival time when micro-seismic waves corresponding to each micro-seismic source are transmitted to each sensor in the first monitoring area; determining the micro-seismic source corresponding to the minimum time residual value as a target point based on the observation arrival time and the calculation arrival time when the micro-seismic wave corresponding to each micro-seismic source is propagated to each sensor in the first monitoring area; microseismic frequency and position information of a target point are collected; and if the micro-seismic frequency of the target point is greater than a preset threshold value, outputting first prompt information of a coal mining super-layer. According to the method, the micro-seismic frequency of the target point is judged through the micro-seismic technology, if the micro-seismic frequency of the target point is larger than the preset threshold value, the first prompt information of the coal mining super-layer is output, limitation of coal seam geological conditions is avoided, and real-time accurate monitoring of coal mining can be achieved.
Description
technical field [0001] The present application relates to the field of computer technology, in particular to a coal mining monitoring method, device and computer equipment. Background technique [0002] In coal mining, the mining rules must be strictly followed, and the working face should be mined according to the plan. If cross-border or super-layer mining will not only bring a lot of economic disputes, but also bring serious security risks. Therefore, the monitoring of coal mine cross-border and super-layer mining behavior is very important. [0003] At present, the commonly used means of monitoring transboundary and superlayer mining include on-site measurement methods such as drilling method and hollow inclusion stress gauge, as well as theoretical calculation and numerical simulation methods such as generalized anti-projection coefficient and limit equilibrium theory. [0004] The field measurement method needs to compare the monitoring points before and after mining...
